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 durations 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.

Each frequency range (Aw–Dw, Gw) offers 26 frequency banks with up to 64 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1 ... 20
Channel 64 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U1 ... U6
Channel 64 – freely selectable frequency
Each of the channels in the frequency banks “1” to “20” has been factory-preset to a fixed
frequency (frequency preset). The factory-preset frequencies within one frequency bank are
intermodulation-free. These frequencies cannot be changed.
For an overview of the frequency presets, please refer to the supplied frequency information
sheet. Updated versions of the frequency information sheet can be downloaded from the
EM 2000 product page on our website at www.sennheiser.com.

Setting up the receiver on a flat surface
Do not fit the device feet when mounting the receiver into a 19” rack.
왘 Clean the base of the receiver where you want to fix the device feet.
왘 Fit the device feet to the four corners of the receiver.
왘 Place the receiver on a flat, horizontal surface. Please note that the device feet can leave
stains on delicate surfaces.
왘 Connect the antennas (see page 9).
Mounting the receiver into a 19” rack
CAUTION! Risks when rack mounting the receiver!
When installing the device in a closed or multi-rack assembly, please consider that, during
operation, the ambient temperature, the mechanical loading and the electrical potentials will
be different from those of devices which are not mounted into a rack.
왘 Make sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the specifications.
왘 Ensure sufficient ventilation; if necessary, provide additional ventilation.
왘 Make sure that the mechanical loading of the rack is even.
왘 When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
왘 When rack mounting, please note that intrinsically harmless leakage currents of the indi-
vidual mains units may accumulate, thereby exceeding the allowable limit value. As a
remedy, ground the rack via an additional ground connection.
쐃
왘 Slide the receiver into the 19” rack.
왘 Secure the rack mount “ears” 쐃 to the rack using four screws (not included in the
delivery).

Putting the receiver into operation
Connecting the antennas
CAUTION! Danger of damage to the antennas
To supply an active directional antenna (e.g. A 3700 for the UHF range) or an antenna
booster (e.g. AB 3700), a direct voltage (which cannot be switched off) is output via the
antenna sockets of the receiver. If you use antennas from other manufacturers, take into
account that these must be installed with direct voltage decoupling. The output voltage
supply is short circuit-proof, but an active antenna connected to this supply increases the
current consumption of the overall device.
9
Putting the receiver into operation
CAUTION! Danger of short-circuit due to uninsulated antennas!
An 11 V voltage is applied to the antennas – even when you switch the receiver off! If unin-
sulated antennas come into contact with objects which conduct electricity, this voltage can
produce sparking and audio interference.
왘 Use insulated antennas.
OR
왘 Always mount uninsulated antennas so that they cannot come into contact with objects
which conduct electricity.
You have the following options:
• For professional use, we recommend connecting remote antennas and, if necessary, using
Sennheiser antenna accessories (see next section).
• If the receiver is to be put into operation without a large amount of installation work, you
can:
– connect the supplied rod antennas to the rear of the receiver (see page 10) or
– use the optional GA 3030 AM antenna front mount kit (see page 11).
