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.

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.

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.

Adjustment tips for the operating menu
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.
̈ Set each transmitter/receiver pair in your multi-channel system to a
different free channel within this frequency bank.

HiDyn plus™ (HDP) noise reduction
RF link
Inherent
noise
of the RF link
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
