2.
Keep these instructions. Always include these instructions when passing the receiver on
to third parties.
3.
Heed all warnings.
4.
Follow all instructions.
5.

Do not block any ventilation openings. Install in accordance with the manufacturer's
instructions.
8.
Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
9.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized
plug has two blades with one wider than the other. A grounding type plug has two blades
and a third grounding prong. The wide blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an electrician for replace-
ment of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs, conve-
nience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or
sold with the apparatus. When a cart is used, use caution when moving the cart/appa-
ratus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as power
supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, when the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.
15. To completely disconnect this apparatus from the AC mains, disconnect the power supply
cord plug from the AC receptacle.
16. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain
or moisture.
17. Do not expose this equipment to dripping or splashing and ensure that no objects filled
with liquids, such as vases, are placed on the equipment.
18. The mains plug of the power supply cord shall remain readily
accessible.
Hazard warnings on the rear of the receiver
The label shown on the left is attached to the rear of the receiver. The symbols on this label

within the receiver's enclosure that may be of sufficient magnitude to constitute risk of fire
or electric shock.

Important safety instructions

This symbol is intended to alert the user to the risk of electric shock if the receiver is opened.
There are no user serviceable parts inside. Refer servicing to qualified personnel only.
This symbol is intended to alert the user to the presence of important operating and mainte-
nance instructions in the literature accompanying this receiver.
Overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Replacement parts
When replacement parts are required, be sure the service technician uses replacement parts
specified by Sennheiser or those having the same characteristics as the original part. Unau-
thorized substitutions may result in fire, electric shock, or other hazards.
Safety check
Upon completion of any service or repairs to this device, ask the service technician to perform
safety checks to determine that the device is in safe operating order.
Danger of hearing damage due to high volumes
This is a professional receiver. Commercial use is subject to the rules and regulations of the
trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to
expressly point out possible health risks arising from use.
This receiver is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the
sound pressure corresponding to the maximum permissible volume which is by law (in some
countries) allowed to affect your hearing for the duration of a working day. It is used as a
basis according to the specifications of industrial medicine. Higher volumes or longer dura-
tions can damage your hearing. At higher volumes, the duration must be shortened in order
to prevent hearing damage. The following are sure signs that you have been subjected to
excessive noise for too long a time:
· You can hear ringing or whistling sounds in your ears.
· You have the impression (even for a short time only) that you can no longer hear high
notes.
Intended use
Intended use of the EM 2000 receiver includes:
· having read these instructions, especially the chapter "Important safety instructions",
· using the device within the operating conditions and limitations described in this instruc-
tion manual.
"Improper use" means using the device other than as described in these instructions, or
under operating conditions which differ from those described herein.

The EM 2000 and EM 2050 rack-mount receivers
This receiver is part of the 2000 series. With this series, Sennheiser offers high-quality state-
of-the-art RF transmission systems with a high level of operational reliability and ease of use.
Transmitters and receivers permit wireless transmission with studio-quality sound.
Features of the 2000 series:
· Optimized PLL synthesizer and microprocessor technology
· HDX noise reduction system
· Pilot tone squelch control
· True diversity technology
· Switching bandwidth of up to 75 MHz
· Safe configuration of a multi-channel system via a network
· Scan function (Easy Setup) for scanning the frequency banks for unused channels
Areas of application
The receiver can be combined with the following transmitters of the 2000 series:
The transmitters are available in the same UHF frequency ranges and are equipped with the
same frequency bank system with factory-preset frequencies. An advantage of the factory-
preset frequencies is that
· a transmission system is ready for immediate use after switch-on,
· several transmission systems can be operated simultaneously on the preset frequencies
without causing intermodulation interference.
The frequency bank system
The receivers are available in 5 UHF frequency ranges with up to 3,000 receiving frequencies
per frequency range:
