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.

Setting up the receiver on a flat surface

Do not fit the device feet when mounting the receiver into a 19” rack.
Clean the base of the receiver where you want to fix the device feet.Fit the device feet to the four corners of the receiver.Place the receiver on a flat, horizontal surface. Please note that the device feet can leave
stains on delicate surfaces.
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.
Make sure that the ambient temperature within the rack does not exceed the permissible
temperature limit specified in the specifications.
Ensure sufficient ventilation; if necessary, provide additional ventilation.Make sure that the mechanical loading of the rack is even.When connecting to the power supply, observe the information indicated on the type
plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
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.
Slide the receiver into the 19” rack.Secure the rack mount “ears” 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.
Use insulated antennas.
OR
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).

Connect the two supplied rod antennas or two remote antennas (optional accessories) to
the BNC sockets and of the first receiver.
Use BNC cables to daisy-chain the receivers as shown in the diagram on the left.
• To supply an active directional antenna, a direct voltage (which cannot be
switched off) is output via the antenna sockets and of the receivers.
• In order to obtain a good reception quality, we recommend not to daisy-chain more than 8 receivers.
• If you set a daisy-chained receiver to standby mode (see “Switching the receiver on/off” on page 14), the integrated antenna splitter remains active.

Adjustment range: 5 to 25 dBμV, adjustable in 2-dB steps, can be switched off
The squelch eliminates annoying noise when the transmitter is switched off or when there is no longer sufficient transmitter power received by the receiver.
CAUTION! Danger of hearing damage and material damage!
If you switch the squelch off or adjust the squelch threshold to a very low value, loud hissing noise can occur in the receiver. The hissing noise can be loud enough to cause hearing damage or overload the loudspeakers of your system!
Always make sure that the squelch is switched on.Before adjusting the squelch threshold, set the volume of the headphone output (see
page 14) and the audio output level to the minimum (“AF Out”, see page 25).
Never change the squelch threshold during a live transmission.
Adjust the squelch threshold – with the transmitter switched off – to the lowest possible
setting that suppresses hissing noise.
If you adjust the squelch threshold to a high value, the transmission range will be reduced under adverse RF reception conditions.

Synchronizing transmitters with receivers

Synchronizing transmitters with receivers
When synchronizing a transmitter with a receiver, please observe the following:
Only use a transmitter and a receiver from the same frequency range (see the
type plates on the transmitter and the receiver).
Make sure that the desired frequencies are listed in the enclosed frequency infor-
mation sheet.
Make sure that the desired frequencies are approved and legal in your country
and, if necessary, apply for an operating license.

Synchronizing a transmitter with the receiver – individual operation

Upon delivery, transmitter and receiver are synchronized with each other. If, however, you cannot establish a transmission link between transmitter and receiver, you have to synchro­nize the channels of the devices:
With the receiver, perform a frequency preset scan to scan the frequency banks for
unused channels (“Scan New List”, see page 23). Then “Sync” appears on the display panel of the receiver.

Synchronizing transmitters with receivers – multi-channel operation

In order to ensure an intermodulation-free transmission, use the same frequency bank for all transmission links.
Combined with 2000 series transmitters, 2000 series receivers can form transmission links that can be used in multi-channel systems. In multi-channel operation, the receivers are remote controlled via a PC running the “Wireless Systems Manager” (WSM) software. For further information on downloading the software, visit the ew G3 product page on our website at www.sennheiser.com.

Advantages of controlling the receivers via the “Wireless Systems Manager” (WSM) software:
• Detailed overview of all receiving channels
• Remote control of all receivers in the network
• Combination of receivers of different frequency ranges (see page 4).
31
Synchronizing transmitters with receivers
Launch the “Wireless Systems Manager” (WSM) software.To scan for unused receiving frequencies and to configure the receivers, proceed as
described in the instruction manual of the “Wireless Systems Manager” (WSM) software.
Set the corresponding transmitter to the selected frequency bank and to the selected
channel either by synchronizing the transmitter with the receiver ( setting the frequency bank and the channel manually (see the instruction manual of the transmitter). Your multi-channel system is now set up.
Operation without
network
If you want to set up a multi-channel system without using the WSM, proceed as follows:
Switch off all transmitters of your system that are to be automatically configured.
Channels used by switched-on transmitters are displayed as “used”.
With one of the receivers, perform a frequency preset scan to scan the frequency banks
for unused channels (“Scan New List”, see page 23). Then “Sync” appears on the display panel of the receiver.

Recommendations and tips

Recommendations and tips
... for optimum reception
• Transmission range depends to a large extent on location and can vary from about 10 m to about 150 m. There should be a “free line of sight” between transmitting and receiving antennas.
• If, with the EM 2000 receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable.
• To avoid overloading the receiver, observe a minimum distance of 5 m between transmit­ting and receiving antennas.
• Observe a minimum distance of 50 cm between receiving antennas and metal objects (such as cross members or reinforced-concrete walls). Align the antennas upwards in a V-shape.
... for multi-channel operation
• Each of the frequency banks “1” to “20” accommodates factory-preset receiving frequencies which are intermodulation-free. For possible frequency combinations, please refer to the supplied frequency information sheet.
• The channels in the frequency banks “U1” to “U6” can be assigned freely selectable frequencies (see page 26).
• When using several transmitters simultaneously, interference can be avoided by main­taining a minimum distance of 20 cm between two transmitters.
• Use accessories recommended by Sennheiser for multi-channel applications (see page 37).
