provide some protection against voltage surges and built-up static
charges. Article 810 of the National Electrical Code, ANSI/NFPA No.
70-1984, provides information with respect to proper grounding of
the mast and supporting structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding conductors, location of
antenna discharge unit, connection to grounding electrodes and
requirements for the grounding electrode.
a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2)
aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze
wire, or larger, as a ground wire.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4-6 feet (1.22 - 1.83 m) apart.
c. Mount antenna discharge unit as close as possible to where lead-
in enters house.
d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper,
or the equivalent, when a separate antenna-grounding electrode
is used. see NEC Section 810-21 (j).

3. FRONT PANEL CONTROLS
2. ANTENNA CONNECTION
4. REMOTE CONTROL HANDSET
background image
10. NAD-LINK IN, OUT
The NAD-Link connector is used to pass commands from other
units fitted with NAD-Link connectors. This allows centralised
control of a complete system, and also allows some of the basic
functions of other NAD components (such as a CD player or
cassette-deck) also equipped with NAD-Link to be controlled with
the amplifier's remote control. To function with such other units,
connect the C730's NAD-Link Out to the NAD-Link In on the other
unit. NAD-Link connectors can be daisy-chained, IN to OUT, so
that a whole system can be controlled from the remote control
facilities of one unit.
NOTES:
It is advisable not to connect NAD-Link if these units that
have their own built-in remote control command receiver and are
positioned together, in direct view from the remote control
handset. If you are unsure, try operating the products without
NAD-Link first; If the unit responds to the remote control
command, it will not be necessary to connect NAD-Link.
Never loop the last unit back to the first NAD unit in the NAD-Link
chain. Unplug all units from the mains before connecting or
disconnecting NAD-Link.
11. SOFT CLIPPINGTM
When an amplifier is driven beyond its specified power output, a
hard, distorted sound can be heard on very loud sounds. This is
caused by the amplifier cutting off or "hard clipping" the peaks of
sound that it was not designed to reproduce. The NAD Soft
ClippingTM circuit gently limits the output of the system to
minimise audible distortion if the amplifier is overdriven.
If your listening involves moderate power levels you may leave the
Soft ClippingTM switch to Off. If you are likely to play at high levels,
that could stretch the amplifier's power capability, then switch Soft
Clip On.
12. 12V TRIGGER OUT
This output allows to remotely switch on or off ancillary
equipment such as a tuner, power amplifier, etc. which are also
equipped with a 12V trigger input. This can also be an AC outlet
power strip equipped with a 12V trigger input. The 12V trigger
output is activated whenever the unit is in switched to normal
operational mode from Stand-by or Off.
For switching Stand-by/Power On of an external component
through the C730, connect the12V-trigger output of the C730 to
the remote component's DC input jack. The plug required is a
standard 3.5mm Mini-Jack plug ("mono"): The tip is the live or
+ connection, the shaft of the input jack is the 12V-trigger - or
ground connection.
NOTES:
Check the specifications of the Trigger input terminal on the
other components to ensure these are compatible with the C730's
12V-trigger output. NAD components equipped with 12V input
triggers are fully compatible with the C730's 12V output trigger.
The C730's 12V-trigger output voltage is 12V DC. The total
maximum current must not exceed 200mA. Typically, NAD 12V
input triggers draw less than 10mA of current. Before making any
connections to any 12V trigger input or output, make sure all
components are disconnected from the AC mains.
Failure to observe the above may result in damage to the C730 or
any ancillary components attached to it. If in doubt over the
connections, installation and operation of the 12V trigger output
consult your NAD dealer.
13. SPEAKERS
Connect the right speaker to the terminals market "R +" and
"R-" ensuring that the "R+" is connected to the "+" terminal on
your loudspeaker and the "R-" is connected to the loudspeaker's
"-" terminal. Connect the terminals marked "L+" and "L-" to the
left speaker in the same way.
Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire
to connect loudspeakers to your NAD C730. The high-current binding
post terminals can be used as a screw terminal for cables terminating
in spade or pin sockets or for cables with bare wire ends.
BARE WIRES AND PIN CONNECTORS
Bare wires and pin sockets should be inserted into the hole in the
shaft of the terminal. Unscrew the speaker terminal's plastic
bushing until the hole in the screw shaft is revealed. Insert the pin
or bare cable end into the hole and secure the cable by tightening
down the terminal's bushing.
Ensure bare wire from the speaker cables does not touch the back
panel or another socket . Ensure that there is only 1/2" (1cm) of
bare cable or pin and no loose strands of speakers wire.
NOTE:
Make sure the speaker impedance is 4 ohms or more
when connecting only one pair of speakers; make sure the
speaker impedance for all speakers is over 8 ohms when
connecting two sets of speakers.
14. AC LINE CORD
Plug the AC power cord into a live AC wall socket. Make sure all
connections have been made before connecting to mains.
15. SWITCHED AC OUTLET
The AC power cord of another component may be plugged into
this accessory outlet. Components plugged into this outlet will be
switched On and Off by the POWER button on the front panel or
by the ON and STAND-BY button on the remote control handset.
NOTE:
The total power consumption of any components
connected to the AC outlets may not exceed 100 Watts.
FRONT PANEL CONTROLS (FIG 3)
1. POWER ON/OFF
Press the POWER button to switch the receiver On. The Stand-by
indicator (No. 2) over the power button will light up amber and
after a short pause will turn to green to indicate the receiver is
now ready for normal operation.
Pressing the POWER switch again will turn the unit OFF
completely, it will not respond to the remote control.

NOTES ON INSTALLATION
Your NAD C730 should be placed on a firm, level surface. Avoid
placing the unit in direct sunlight or near sources of heat and
damp. Allow adequate ventilation. Do not place the unit on a soft
surface like a carpet. Do not place or it in an enclosed position
such a bookcase or cabinet that may impede the air-flow through
the ventilation slots. Make sure the unit is switched off before
making any connections.
The RCA sockets on your NAD C730 are colour coded for
convenience. Red and white are Right and Left audio respectively,
and yellow for NAD Link. Use high quality leads and sockets for
optimum performance and reliability. Ensure that leads and
sockets are not damaged in any way and all sockets are firmly
pushed home.
For best performance, use quality speaker leads of 16 gauge
(1.5mm) thickness or more. If the unit is not going to be used for
some time, disconnect the plug from the AC socket.
Should water get into your NAD C730, shut off the power to the
unit and remove the plug from the AC socket. Have the unit
inspected by a qualified service technician before attempting to
use it again. Do not remove the cover, there are no user-
serviceable parts inside. Use a dry soft cloth to clean the unit.
If necessary, lightly dampen the cloth with soapy water. Do not use
solutions containing benzol or other volatile agents.
REAR PANEL CONNECTIONS (FIG 1)
1. FM ANTENNA
A ribbon wire FM antenna is included and should be connected to
the FM connector at the rear of the unit using the supplied
"balun" adapter (see fig 2). The ribbon aerial should be mounted
on a vertical surface and placed so that it forms a "T".
Experiment with placement of the antenna to find the position that
gives the best signal strength and lowest background noise. An
inadequate FM signal normally results in high levels of hiss,
especially in stereo, and interference from external electrical
sources. In areas of poor FM reception, the tuner section's
performance can be improved by using an externally mounted FM
antenna. A qualified aerial installer will be able to advise and fit a
recommended aerial for your reception conditions.
2. AM ANTENNA
An AM loop antenna is supplied with the NAD C730 and is
required for AM reception. To connect the AM antenna, first press
the keys on the Antenna terminals downwards. Insert the bare
antenna wires into the two terminal holes and push the connector
keys upwards again to secure the connection (see fig 2).
Test various positions for the antenna but always ensure the loop
is placed vertically for best reception. Placing the antenna close to
large metal items such as metal shelves or radiators may interfere
with reception.
3. DISC INPUT
Input for additional line level input signals such as CD, Mini Disc
player or the output signal from a step-up amplifier for a
turntable. Use a twin RCA-to-RCA lead to connect the auxiliary
unit's left and right "Audio Outputs" to this input.
4. CD INPUT
Input for a CD or other line-level signal source. Use a twin RCA-
to-RCA lead to connect the CD player's left and right "Audio
Outputs" to this input. The NAD C730 only accepts analogue
signals from your CD player.
5. VIDEO INPUT
Input for the audio signal from a stereo VCR (or stereo
TV/Satellite/Cable receiver) or other line-level audio source.
Using twin RCA-to-RCA leads, connect to the left and right "Audio
Out" of the unit to these inputs. Note: These are audio inputs only.
6. AUX INPUT
Input for additional line level input signals such as another CD
player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's
left and right "Audio Outputs" to this input.
7. TAPE 2 IN, OUT
Connections for analogue recording and playback to an audio
tape recorder of any type. Using twin RCA-to-RCA leads, connect
to the left and right "Audio Output" of the tape machine to the
TAPE 2 IN sockets for playback. Connect the left and right "Audio
Input" of the tape machine to the TAPE 2 OUT sockets for
recording.
8. TAPE 1 IN, OUT
Connections for analogue recording and playback to a secondary
audio tape recorder of any type. Using twin RCA-to-RCA leads,
connect to the left and right "Audio Output" of the tape machine
to the TAPE 1 IN sockets for playback and tape monitoring.
Connect the left and right "Audio Input" of the tape machine to the
TAPE 1 OUT sockets for recording.
9. PRE OUT
The NAD C730 allows for the connection of a different or additional
power amplifier. If you are using an external stereo power
amplifier, use a twin RCA-to-RCA lead to connect to the left and
right "Audio Input" of the Power amp to the PRE OUT 1 sockets.
NOTES:
Always turn the C730 and associated external power
amplifiers off before connecting or disconnecting anything to the
PRE-OUT sockets.
The PRE-OUT output signal will be affected by the NAD C730's
volume and tone control settings.

8. PRESET/TUNE
The Preset/Tune button toggles between two different modes:
a) Preset mode: In this mode you can use the Tune/Preset
or
buttons (No. 9) to select a Preset. When Preset Mode
is selected "PRESET" will scroll once through the display and
the PRESET indicator lights up in the display.
b) Tune mode: By pressing the Preset/Tune button (No. 9)
or
you can engage automatic or manual tuning
respectively down or up the frequency band. When Tune mode
is selected, "TUNE" will scroll through the display once.
9. PRESET/TUNE
AND
The function of these buttons depends on the tuning mode
selected with the Preset/Tune button (No. 8). The Preset/Tune
button toggles between the two operation modes:
a) Preset mode (indicated in the display area): Press the
(down) button to scroll to a lower number Preset; press the
(up) button to scroll to a higher Preset number. This is a
"wrap-around" function, so that going from the highest
number Preset, the tuner will go to the lowest Preset number
or vice-versa when tuning either up or down.
b) Tune mode: Press the
(down) or
(up) button for
more than 1 second to engage automatic tuning respectively up
or down the frequency band. The tuner will search
automatically for the first reasonably strong radio station,
where it will stop. Press the Down/Up button again for 1
second to start searching again.
By briefly tapping the
(down) or
(up) buttons you can
engage manual tuning respectively up or down the frequency band
for precise tuning to a specific frequency. With each successive tap
of the keys, the tuner will take 0.05 MHz steps on FM so you can
accurately tune into the desired frequency. For AM the tuning steps
are set at 10 kHz (120V version) or 9 kHz (230V version).
This tuning mode can also be useful when trying to receive a radio
station, which is too weak for the auto search mode. When tuned
accurately to a station, "TUNED" will light up in the display. The
muting circuit, however may suppress very weak radio station
signals. If such a very weak station is in stereo it will have a high
level of background hiss. Switching to Mono Mode and
disengaging the muting circuit by depressing the FM MUTE/MODE
button (No. 5) will allow the station to be heard and will cancel
most or all of this background noise.
NOTES:
Automatic tuning is available on both FM and AM.
Even if the C730 is in Tune Mode, the remote control's Preset Up
and Down buttons will only change presets.
The Preset/Tune
and
buttons are also used in
conjunction with the Memory (No. 4) and Display (No. 7) buttons
to add and memorise user defined names to Presets. Refer to the
separate chapter "Storing, Recalling and Labelling Presets" for
more information.
10. DISPLAY AREA
The display area gives all vital information on the status of the
receiver. Displayed are:
· Which input is selected
· Volume MUTE On
· Tape Monitor engaged
· Tone Defeat On
· Band and frequency of current station, RDS PS (station name),
or RDS Radio Text. The latter two only if RDS is available; select
using the Display button (No. 7).
· If an FM Stereo broadcast is received.
· If the FM station also broadcasts RDS.
· If "Memory" has been engaged
· Preset number if the current station is stored in the tuner's
memory bank.
· If Blend and FM Mute/Mode are switched On.
· Radio Signal Strength. The bars just below "ANTENNA" indicate
the radio station's signal strength. The more bars are lit, the
stronger the station.
NOTE:
The infrared sensor, which receives commands from a
remote control (not supplied), is located on the left side of the
display window. There must be a clear line-of-sight path from the
remote control to this window; if that path is obstructed, the
remote control may not work.
11. VOLUME
The VOLUME control adjusts the overall loudness of the signals
being fed to the loudspeakers. It is motor driven and can be
adjusted from the remote control handset. The VOLUME control
does not affect recordings made using the Tape outputs but will
affect the signal going to the Pre-amp output (Pre Out).
On the remote control handset, press the MUTE Button to
temporarily switch off the sound to the speakers and headphones.
Mute mode is indicated by "MUTE" flashing in red in the display
area. Press MUTE again to restore sound. Mute does not affect
recordings made using the Tape outputs but will affect the signal
going to the Pre-amp output (Pre Out).
12. HEADPHONE SOCKET
A 1/4" stereo jack socket is supplied for headphone listening and
will work with conventional headphones of any impedance.
Inserting a headphone jack into this socket automatically switches
off the loudspeakers. The volume, tone and balance controls are
operative for headphone listening. Use a suitable adapter to
connect headphones with other types of sockets, such as 3.5mm
stereo "personal stereo" jack plugs.

REMOTE CONTROL
STANDBY/ON button (No.1)
When the receiver is switched On, pressing the green On/Off
button on the remote handset will put the receiver into Standby
mode and the Power indicator will turn amber. The amber Power
indicator shows that power is being supplied, but the system is
currently in the Standby Mode. Press again to switch the receiver
On from Stand-by mode.
ON and OFF buttons (No.2)
Besides the On/Off toggle function of the green button (No. 1), the
NAD C730 remote also has a separate On and Off button. This can
be particularly useful to keep components within a system "in-
sync": This way all components will switch to stand-by when Off is
pressed or switch to operating mode when On is pressed, instead
of some components switching On when the receiver is switched
to Stand-by. (Note that the other components have to be capable
of responding to the separate On and Off commands as well).
Press the ON button to switch the unit from Stand-by to the
operating mode; The Stand-by indicator (Fig. 2; No. 2) will turn
from amber to green to indicate the receiver is ready for use.
Press the OFF button to switch the unit to the Stand-by mode: The
Stand-by indicator will light up amber.
NOTE:
In Stand-by mode the C730 uses very little power.
However, it is recommended that you switch the unit totally off if
it is not going to be used for more than a couple of days. Switch
off completely by pressing the POWER button on the front panel
(No. 1), all lights will extinguish.
2. STAND-BY INDICATOR
This indicator lights up green during normal operation. In Stand-
by mode the indicator will light up amber. Refer to section 1 in
this chapter for more information. The indicator will blink when
the receiver receives a remote control command from the
supplied handset.
If the receiver goes into "protection" mode the Led will flash
continuously at a rate of two flashes per second. This can occur if
there is a short circuit in the speaker wiring. Switch the unit off
totally using the Power button on the front panel (No 1) and
check all the cables and connections both at the receiver side and
at the loudspeakers side. Once all the connections are restored
correctly, switch the Power button (No 1) on, with the volume
initially set low and then resume normal operation. If the problem
persists, switch of the power completely and consult your dealer.
3. BLEND
Weak or remote stereo radio stations are sometimes received with
noise and hiss as the antenna signal is too weak. By switching the
tuner to mono will reduce the amount of noise and hiss but at the
expense of any stereo information. The NAD Blend feature will
allow you to reduce the amount noise and hiss but still retain
some level of stereo separation, instead of mono. The Blend
button toggles between engaging or disengaging the Blend feature;
when engaged, "BLEND" lights up in the display.
NOTE:
The "Blend" status can be stored for individual presets.
Refer to the separate chapter "Storing, Recalling and Labelling
Presets" for more information.
4. MEMORY
The Memory is used to store stations into the Preset Memory bank
and to store user defined names for non-RDS Preset stations. When
Memory is pressed during normal operation, the Preset number
and the red "MEMORY" indicator will flash in the Display Panel. If
no other buttons are pressed within 12 seconds, the receiver will
revert to its previous state. Refer to the separate chapter "Storing,
Recalling and Labelling Presets" for more information.
5. FM MUTE/MODE
This button combines two functions; it switches the receiver's
tuner section from Stereo to Mono and disengages the muting
circuitry at the same time. The muting circuit will mute the tuner
in between radio stations when searching or tuning. This way the
tuning noise is avoided.
The muting circuit however may suppress very weak radio station
signals. If a weak station is in stereo it will have a high level of
background hiss. Switching to Mono Mode and disengaging the
muting circuit by depressing the FM MUTE/MODE button will
allow the station to be heard and will cancel most or all of this
background noise.
In normal operation the mute circuit is engaged, the display
indicates "FM MUTE". Press the FM Mute/Mode button to
disengage the muting circuit and switch from stereo to mono
reception. "FM MUTE" in the display will extinguish. Press the FM
Mute/Mode switch again to return to Auto Stereo FM operation.
NOTE:
The "FM Mute/Mode" status can be stored for individual
presets. Refer to the separate chapter "Storing, Recalling and
Labelling Presets" for more information.
6. AM/FM
The AM/FM button switches the tuner from the AM band to the FM
band and vice-versa. The Display Panel shows the frequency of the
tuned station and which band is selected. The FM tuning is in 0.05
MHz increments, AM tuning is in 9 kHz or 10 kHz increments,
depending on the version.
7. DISPLAY
With stations carrying RDS information, The Display button scrolls
between three different display modes, each successive push of
the button engages the next one of the three modes:
a) In the default mode, the station's RDS name is displayed,
Program Service (PS; normally the station's calling letters, BBC
R3, for instance).
b) From the default mode, press the button once to view Radio Text
(RT). This can be additional information such as the presenter's
or program's name; what song is playing, etc. This text scrolls
continuously over the 8 alphanumeric display segments.
c) Press the button from the display RT mode to display the station
frequency. Press again to return to the default mode (a).
When tuned to a non-RDS station
The Display button toggles the display to show either the station
frequency or user entered station name. If no user name was
entered the display will indicate "NO RDS".
The Display button is also used to label non-RDS stations with a
name. Refer to the separate chapter "Storing, Recalling and
Labelling Presets" for more information.

for reference).
4) Press Display to move one place to the right to enter the next
desired character.
5) Use the Tune/Preset buttons again to select the next character
in the name.
6) Repeat steps 3 to 5 until name is complete or all eight places
have been filled (up to 8 characters).
7) Press Memory once to finish the labelling procedure. Press
Memory again to store the completed name.
There are 37 characters available including a blank space.
NOTE:
This function is only available for non-RDS stations. RDS
stations will always display their transmitted name and cannot be
over-written.
TO MAKE A RECORDING
When any source is selected, its signal is also fed directly to any
tape machine connected to the TAPE 1 or TAPE 2 OUTPUTS on the
rear panel for recording.
TAPE TO TAPE COPYING
You can copy between two tape machines connected to your NAD
C730. Put the source tape in the recorder connected to Tape 2 and
the blank tape into the recorder connected to Tape 1. By selecting
TAPE 2 Input, you can now record from Tape 2 to Tape 1 and
monitor the signal coming from the original tape.
REMOTE CONTROL HANDSET (FIG 4)
The Remote Control handset handles all the key functions of the
NAD C730 and has additional controls to remotely operate NAD
Tuners, Cassette and CD machines. It will operate up to a distance
of 16ft (5m). Alkaline batteries are recommended for maximum
operating life. Two AAA (R 03) batteries should be fitted in the
battery compartment at the rear of the Remote Control handset.
When replacing batteries, check that they have been put in the right
way round, as indicated on the base of the battery compartment.
Please refer to previous sections of the manual for a full
description of individual functions.
When a command from the remote control is received, the Stand-
by/protection indicator will blink. Note that the indicator may also
blink when receiving commands not necessarily for the C730 but
for other components in the system.
1. STANDBY/ON BUTTON
When the amplifier is switched On, pressing the green On/Off
button on the remote handset will put the NAD-370 into Standby
mode and the Power indicator will turn amber. The amber Power
indicator shows that power is being supplied to the NAD-370, but
the system is currently in the Standby Mode. Press again to switch
the amplifier On from Stand-by mode.
2. POWER ON & OFF
Besides the On/Off toggle function of the green button (No. 1), the
NAD C730 remote also has a separate On and Off button. This can
be particularly useful to keep components within a system "in-
sync": This way all components will switch to stand-by when Off is
pressed or switch to operating mode when On is pressed, instead
of some components switching On when the amplifier is switched
to Stand-by. (Note that the other components have to be capable
of responding to the separate On and Off commands as well).
Press the ON button to switch the unit from Stand-by to the
operating mode; The Stand-by indicator (Fig. 2; No. 2) will turn
from amber to green and the indicator for the last selected input
will blink and light up. Press the OFF button to switch the unit to
the Stand-by mode: The Stand-by indicator will light up amber.
3. SPEAKERS A & B
These buttons are inoperative on the C730
4. MUTE
Press the MUTE Button (No. 4) to temporarily switch off the sound
to the speakers and headphones. Mute mode is indicated by
"MUTE" flashing in red in the display area. Press MUTE again to
restore sound. Mute does not affect recordings made using the
Tape outputs but will affect the signal going to the Pre-amp output
(Pre-Out).
5. INPUTS
The input selector buttons (No. 5) perform the same functions as
the buttons labelled the same on the front panel. There are a few
differences and extra functions with the remote control handset
however:
The TUNER AM & FM buttons select the Tuner input and
respectively the AM or FM waveband. The receiver will tune to the
last station selected on either AM or FM band.
NOTE:
The Video 2 and Video 3 input selector buttons are
inoperative.

13. INPUT SELECTORS
These buttons select the active input to the NAD C730 and the
signal sent to the loudspeakers, the Tape outputs and the PRE OUT
sockets. The buttons on the remote control handset duplicate
these buttons, with the exception of the tuner input; see below.
The display indicates which input has been selected.
DISC Selects a line-level source connected to the DISC sockets as
the active input.
CD Selects the CD (or other line-level source) connected to the
CD sockets, as the active input.
VIDEO Selects the VCR (or stereo TV/Satellite/Cable receiver)
connected to the VIDEO sockets, as the active input.
AUX Selects a line-level source connected to the AUX sockets, as
the active input.
TUNER Selects the tuner as the active input. The receiver will
return to the last selected preset or frequency. The remote control
handset has separate buttons for AM and FM; pressing either one
will select the tuner as the active input and revert to the last station
tuned to on respectively the AM or FM band.
TAPE 2 Selects Tape 2 as the active input.
TAPE 1 Monitor Selects the output from a tape recorder when
playing back tapes or monitoring recordings being made through
the Tape 1sockets. Press the Tape 1 button once to select it and
again to return to the normal input selection.
Tape 1 is a tape Monitor function which does not override the
current input selection. For example, if the CD is the active input
when TAPE 1 is selected, then the CD signal will continue to be
selected and sent to both the TAPE 1, and TAPE 2 OUTPUT sockets,
but it is the sound from recorder connected to Tape 1 that will be
heard on the loudspeakers. When Tape 1 Monitor is selected,
"TAPE 1" is indicated in the alphanumeric section of the display
for 3 seconds before it defaults to indicating the active input again.
The red box next to the preset number section in the display
indicating "TAPE MONITOR" will remain lit until Tape 1 is
disengaged again.
NOTE:
The remote control handset with the C730 supplied is of a
universal NAD type, designed to operate several NAD models. Some
buttons on this handset are inoperative as the functions aren't
supported by the C730. The Video 2, Video 3 input selector
buttons, tuner Bank button, speakers A and Speakers B buttons on
the remote control handset are inoperative in the case of the C730.
NOTE:
Make certain that the volume control is turned to
minimum (fully anti-clockwise) before connecting or
disconnecting headphones. Listening at high levels can damage
your hearing.
14. BASS & TREBLE CONTROLS
The NAD C730 is fitted with BASS and TREBLE tone controls to
adjust the tonal balance of your system.
The 12 o'clock position is "flat" with no boost or cut and a detent
indicates this position. Rotate the control clockwise to increase
the amount of Bass or Treble. Rotate the control anti-clockwise to
decrease the amount of Bass or Treble. The Tone controls do not
affect recordings made using the Tape outputs but will affect the
signal going to the Pre-amp output (Pre Out).
15. TONE DEFEAT
The TONE DEFEAT switch by-passes the tone control section of the
NAD C730. If the Tone Controls are not normally used and left in
the 12 o'clock position, then it is advisable to switch out the Tone
Control section altogether by using this switch. In the "out"
position, the Tone Control circuits are active, pushing the TONE
DEFEAT switch "in" bypasses the Tone Control section.
16. BALANCE
The BALANCE control adjusts the relative levels of the left and right
speakers. The 12 o'clock position provides equal level to the left
and right channels. A detent indicates this position.
Rotating the control clockwise moves the balance towards the
right. Rotating the control anti-clockwise moves the balance to the
left. The BALANCE control does not affect recordings made using
the Tape outputs but will affect the signal going to the Pre-amp
output (Pre Out).
STORING, RECALLING
AND LABELLING PRESETS
Up to 30 presets in total can be stored in the C730's memory bank;
these can be any mix of either AM or FM stations. When scrolling
through the presets, empty preset places will be skipped; it is thus
possible to go from preset No. 4 to No. 7 without having seen No.
5 and 6. With the presets you can also store whether you want
Blend (No. 3) and FM Mute/Mode (No. 5) to be activated as well
every time you recall the preset.
TO STORE A PRESET
· Tune to the radio station you wish to enter into a Preset (refer
to this chapter's section 9). If the station is transmitting RDS
information, the RDS indicator will light up and station initials
or name will be shown in the Display Panel. If a non-RDS
station is found, then just the frequency will be shown.
· Select Blend (No. 3) or FM Mute/Mode (No. 5) if desired.
· To store that station as a Preset, press Memory (No. 4). The
Preset number and the red "MEMORY" indicator are flashing
in the Display Panel. The lowest available empty preset number
will be shown. If no other buttons are pressed within 8
seconds, the tuner will revert to its previous state.
· Press Memory again to store the preset. If you wish to assign a
different preset number, press either the Preset/Tune
or
button to select the desired preset number. You can over-
write an existing preset. If the preset number already has been
assigned, "MEMORY" will stop blinking, but the preset will
continue to blink. When you have selected the desired preset
number, press Memory again to store the station.
NOTES:
You can enter a new station into an unused Preset or
over-write an existing programmed Memory Preset. By doing this
you will replace all the data previously held on that Preset number.
When Memory is pressed during normal operation, the Preset
number and the red "MEMORY" indicator will flash in the Display
Panel. If no other buttons are pressed within 8 seconds, the tuner
will revert to its previous state. The Memory Presets have a memory
back-up, so they will remain stored for several weeks even if the
Tuner is switched off or unplugged from the mains supply.
RECALLING A PRESET
· To select a Preset station, check if Preset mode is engaged (the
display indicates "PRESET"). If not, press the Preset/Tune
Mode button (No. 8); "PRESET" will now light up in the
display.
· Press either the Preset/Tune
or
buttons (No. 9)
until the right Preset is found and shown in the Display Panel.
Any unused Presets will be skipped; this avoids having to scroll
through empty presets.
