Features
WIDE RANGE AMPLIFIER TECHNOLOGY (WRAT)
WRAT virtually eliminates the adverse effects of counter-
electromotive force by:
1) applying an uncommonly low amount of NFB (negative feed-
back),
2) using carefully selected, high-tolerance, wide range parts in all
critical sections, and
3) incorporating innovative circuit topology based upon decades
of high-end amplifier design experience -- the final result is flat
response beyond 100 kHz.
AUTO POWER ON/OFF FUNCTION
You can turn on and off the ADM-2.1 via a signal input to the
AUDIO IN jacks or 12V TRIGGER IN jack.
AUDIO IN/OUT LINK FUNCTION
The signal inputs from the AUDIO IN jacks are output from the
AUDIO OUT jacks. When used as a 2 channel amplifier in a multi
room configuration, you can connect several ADM-2.1s to enjoy
the same source in several rooms.

Rear panel facilities and connections
GND
Use this GND terminal for connecting the ground (or earth) wire
of other component if humming noise is heard.
AUDIO IN/OUT
These are the analog audio inputs and outputs. Use an RCA-type
audio connection cable to connect the output jacks of the device to
the AUDIO IN jacks on the ADM-2.1. When connecting a control
amplifier or preamplifier, connect the PRE OUT jacks to the
AUDIO IN jacks.
If you connect the AUDIO OUT jacks of the ADM-2.1 to the
AUDIO IN jacks of another ADM-2.1, the signal input at the
AUDIO IN jacks of the ADM-2.1 is also output from the AUDIO
OUT jacks (Audio In/Out Link Function).
If you set the TRIGGER switch to AUDIO, the power of the
connected ADM-2.1 turns on automatically when an audio signal
is supplied to the AUDIO IN jacks (Auto Power On/Off Function).
INPUT LEVEL
Turn this INPUT LEVEL control to adjust the input level of the
signal from the AUDIO IN jacks. Normally, set to MAX.
Note:
When a CD player is connected to the ADM-2.1, be sure to adjust
the INPUT LEVEL control.
Caution:
· Be sure to always refer to the instructions that came with the
component that you are connecting.
· Do not plug in the power cord until all connections have been
made.
· Do not make connections to input or output jacks while the
ADM-2.1 is turned on.
· Always turn the volume of the control amplifier or
preamplifier down before turning on the ADM-2.1.
· For input and output jacks, red connectors (marked R) are used
for the right channel and white connectors (marked L) are used
for the left channel.
TRIGGER
Set this TRIGGER switch before turning on the ADM-2.1.
To turn on the ADM-2.1 with the signal input from the 12V
TRIGGER IN jack, set the TRIGGER switch to 12V TRIGGER.
To turn on the ADM-2.1 with the signal input from the AUDIO IN
jack, set the TRIGGER switch to AUDIO (Auto Power On/Off
Function). If you do not use Auto Power Function, set the
TRIGGER switch to OFF.
12V TRIGGER IN
If the connected control amplifiers or preamplifiers have a 12V
TRIGGER output jack, use 1/8-inch 2P mini-jack cable to connect
the 12V TRIGGER IN jack on the ADM-2.1. This jack works on
between 5 to 12 volts DC. When the ADM-2.1 is in the standby
state and the TRIGGER switch is set to 12V TRIGGER, you can
switch the ADM-2.1 between the on and standby states with
operations at the control amplifier or preamplifier.
Note:
When a plug is connected to the 12V TRIGGER jack, be sure to
connect the analog output jacks (or PRE OUT jacks) of the device
to the AUDIO IN jacks of the ADM-2.1. Otherwise, no sound will
be produced.

· Do not connect any devices other than speakers to these
terminals.
· Be sure not to mistake the positive and negative outputs or the
left and right speakers. Doing so will result in an unnatural
sound space.
· Only connect speakers with an impedance of 6 ohms or higher.
If a speaker with an impedance of less than 6 ohms is
connected, it may damage the ADM-2.1.
· When you are using only one
speaker or when you wish to
listen
to
monaural
(mono)
sound, a single speaker should
never be connected in parallel
to both the right and left-
channel terminals simultane-
ously.
· To prevent damage to cir-
cuitry, never short-circuit the
positive (+) and negative (­)
speaker wire.
AC INLET
Plug the supplied power cord into this AC INLET and then into the
power outlet on the wall.
· Do not use a power cord other than the one supplied with the
ADM-2.1. The power cord supplied is designed for use with
the ADM-2.1 and should not be used with any other device.
