Important safety instructions  
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 have the following meaning:  
This symbol is intended to alert the user to the presence of uninsulated  
dangerous voltage within the receiver’s enclosure that may be of sufficient  
magnitude to constitute risk of fire or electric shock.  
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 maintenance instructions in the literature accompanying  
this receiver.  
Overloading  
Do not overload wall outlets and extension cords as this may result in fire  
and electric shock.  
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 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.

Putting the receiver into operation  
Putting the receiver into operation  
Fitting the device feet  
To ensure that the receiver cannot slip on the surface on which it is placed,  
four self-adhesive soft rubber feet are supplied.  
Do not fit the device feet when rack mounting the receiver.  
CAUTION! Risk of staining of furniture surfaces!  
Some furniture surfaces have been treated with varnish,  
polish or synthetics which might cause stains when they  
come into contact with other synthetics. Despite a thorough  
testing of the synthetics used by us, we cannot rule out the  
possibility of staining.  
̈ Do not place the receiver on delicate surfaces.  
̈ Ensure that the base of the receiver is clean and free from grease  
before fitting the device feet.  
̈ Fit the device feet to the four corners of the receiver as shown.  
Rack mounting  
CAUTION! Risks when rack mounting the receiver!  
When installing the receiver 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.  
̈ The ambient temperature within the rack must not  
exceed the temperature limit specified in the  
specifications.  
̈ When installing the receiver in a rack, take good care not  
to affect the ventilation required for safe operation or  
provide additional ventilation.  
̈ Make sure the mechanical loading of the rack is even to  
avoid  
a
hazardous condition such as  
a
severely  
unbalanced rack.  
̈ When connecting the receiver to the power supply,  
observe the information indicated on the type plate.  
Avoid circuit overloading. If necessary, provide  
overcurrent protection.  
̈ Ensure a reliable mains ground connection of the device  
by taking appropriate measures – especially when you  
are using an extension cable or a multi-outlet power strip.  
̈ When installing the receiver in a closed or multi-rack  
assembly, please note that intrinsically harmless leakage  
currents of the individual devices may accumulate,  
thereby exceeding the allowable limit value. As a remedy,  
ground the rack via an additional ground connection.

Putting the receiver into operation  
The rack mount “ears” are already fitted to the receiver on delivery. To  
mount the receiver into a 19" rack:  
̈ Slide the receiver into the 19" rack.  
̈ Secure the rack mount “ears” 1 to the rack using four screws (not  
included in the delivery).  
Connecting the antennas  
CAUTION! Danger of short-circuit due to uninsulated antennas!  
If you switch the booster supply voltage on, a 12 V DC voltage  
is applied to the antennas – even when you switch the  
receiver off! If uninsulated 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.  
The two antenna inputs O and R allow you to connect either:  
the two supplied antennas to the rear of the receiver (see next section)  
or  
the two supplied antennas to the front of the receiver (see “Mounting  
two remote antennas to the rear of the receiver (see “Connecting and  
In addition, the receiver has two daisy chain outputs P and Q for  
supplying the antenna signals to further receivers (see “Daisy chaining  
Connecting the antennas to the rear of the receiver  
The supplied antennas can be mounted quickly and easily and are suitable  
for all applications where – good reception conditions provided – a  
wireless transmission system is to be used without a large amount of  
installation work.

Adjusting the squelch threshold  
Both receivers are equipped with a squelch that can be adjusted via the  
Squelch” menu. The squelch eliminates annoying noise when the  
transmitter is switched off. It also suppresses sudden noise when there is  
no longer sufficient transmitter power received by the receiver.  
30  
Squelch  
EL  
ame  
Booste  
The squelch can be adjusted in 13 steps from 0 to 30 μV. Selecting a  
smaller value reduces the squelch threshold, selecting a higher value  
increases the squelch threshold. Adjust the squelch threshold – with the  
transmitter switched off – to the lowest possible value that suppresses  
hissing noise.  
If you adjust the squelch threshold to a high value, the  
transmission range will be reduced. Therefore, always adjust the  
squelch threshold to the lowest possible setting.  
If you adjust the squelch threshold to “0”, the squelch is switched  
off. If no RF signal is being received, hissing noise will occur. This  
setting is for test purposes only.  
To adjust the squelch threshold:  
̈ Before adjusting the squelch threshold to a different setting, set the  
volume on a connected amplifier to the minimum.

Multi-channel operation  
Combined with Sennheiser 3000 and 5000 series transmitters, the  
receivers can form transmission links that are suitable for multi-channel  
operation.  
CAUTION! Risk of reception interference!  
If – within the receiver’s frequency range – transmitters  
transmit on channels from different frequency banks,  
reception can be subject to interference and inter-  
modulation. Only the factory-preset frequencies within the  
frequency banks “1” to “6” are interference and  
intermodulation free.  
̈ Set all transmitters of a multi-channel system to different  
channels within the same frequency bank.  
Before putting the transmission links into operation, we recommend that  
you perform a scan in order to find a frequency bank with a sufficient  
number of free channels:  
̈ Switch all transmitters off.  
̈ Use a receiver to scan all frequency banks for free channels (see  
̈ Select a frequency bank with a sufficient number of free channels (see  
̈ Set each transmitter/receiver pair in your multi-channel system to a  
different free channel within this frequency bank.

Transmitter  
Receiver  
This product family is equipped with HDP, the Sennheiser noise reduction  
system that reduces RF interference. It increases the signal-to-noise ratio  
in wireless audio transmission to more than 110 dB. HDP is a wideband  
compander system which compresses the audio signal in the transmitter  
in a 2:1 ratio (related to dB) to lift it above the inherent noise floor of the  
RF link. In the receiver the signal is expanded in an identical and opposite  
way in a 1:2 ratio to restore the original signal, at the same time reducing  
the RF noise to below the noise floor of the receiver.  
HDP has been specially developed for high quality radio microphone  
systems.  
All receivers of the product family feature a AES3 digital audio output for  
digital mixing consoles. In the receiver the audio signal is digitalized as  
early as possible so that the noise reduction (compander) can be realized  
digitally.  
Only transmitters and receivers that are equipped with HDP can  
work correctly with each other. If non HDP equipment was mixed  
with HDP, the dynamic range would be drastically reduced and the  
transmission would sound blunt and flat. HDP is permanently  
active and cannot be switched off.  
Squelch  
Depending on the strength of the received RF signal, the receiver’s audio  
output is opened or muted. Via the “Squelch” menu, the squelch threshold  
can be adjusted in 13 steps from 0 to 30 μV.

Additional information  
Diversity reception  
The receivers operate on the “true diversity” principle:  
A receiving antenna receives not only the electromagnetic waves which  
reach it by a direct path, but also the reflections of these waves which are  
created in the room by walls, windows, ceilings and fittings. When these  
waves are superimposed, destructive interference occurs, which can also  
be called “field strength gaps”. Repositioning the receiving antenna can  
bring a solution. With mobile transmitters, however (which all radio  
microphones are), the “field strength gap” will then occur with a different  
transmitter position. These “field strength gaps” can only be eliminated  
with true diversity receivers.  
In true diversity, instead of one antenna and one receiver there are now  
two antennas and two receiver sections. The antennas are spatially  
separated. By means of a comparison circuit, the receiver section with the  
strongest RF signal is always switched to the common AF output. The risk  
of the occurrence of “field strength gaps” in both antennas at the same  
time is virtually nonexistant.  
The receiver display panel shows the active diversity section (A or B) (see  
Receiver section A  
Receiver section B
