same characteristics as the original part. Unauthorized 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 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:
yYou can hear ringing or whistling sounds in your ears.
yYou have the impression (even for a short time only) that you can no
longer hear high notes.

왘Ensure that the base of the receiver is clean and free from grease
before fitting the rubber feet.
왘Fix the rubber feet to the base of the receiver by peeling off the backing
paper and fitting them as shown in the diagram on the left.
Rack mounting
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.
왘Do not place the receiver on delicate surfaces.
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 within the rack may significantly rise above room
temperature.
왘The ambient temperature within the rack must not exceed
the temperature limit specified in the specifications.
왘When installing the device in a rack, take good care not to
affect the ventilation required for safe operation or provide
additional ventilation.
왘Make sure the mechanical loading of the rack is even to
avoid a hazardous condition such as a severely unbalanced
rack.
왘When connecting the device to the power supply, observe
the information indicated on the type plate. Avoid circuit
overloading. If necessary, provide overcurrent protection.
왘Ensure a reliable mains ground connection of the device by
taking appropriate measures.
왘When installing the device 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.

14
Putting the receiver into operation
The rack mount “ears” are already attached to the receiver at the factory.
To mount the device into a 19" rack:
왘Slide the receiver into the 19" rack.
왘Secure the rack mount “ears” 1to the rack using four screws (not

wireless transmission system is to be used without a large amount of
installation work.
왘Connect the telescopic antennas to the BNC sockets Oand Rat the
rear of the receiver.
왘Align the telescopic antennas upwards in a V-shape.
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.
왘Either use insulated antennas or
왘always mount uninsulated antennas so that they cannot
come into contact with objects which conduct electricity.

15
Putting the receiver into operation

The digital balanced XLR-3M audio output Goutputs the signals of both
receivers in AES3 format.
왘Use a special double-shielded 110 ΩAES3 cable to connect the device
with AES3 digital input to the digital balanced XLR-3M audio
output G.
This ensures that the digital data transmission interferes with the RF
reception.
Note:
A ready-made AES3 cable from Sennheiser is available as an accessory
with a length of 10 m (see “Accessories/spare parts” on page 43).
왘Via the “Clock” menu, select the desired sampling rate (see “Selecting
the sampling rate for digitalization” on page 31).
CAUTION! Damage due to electric current!
If you connect the receiver to an unsuitable power supply, this
can cause damage to the device.
왘Use the supplied mains cable to connect the receiver to the
mains (100 to 240 V AC, 50 or 60 Hz).
왘Ensure a reliable mains ground connection of the receiver –
especially when you are using multi-outlet power strips or
extension cables.

Putting the receiver into operation
Connecting an external word clock generator
The receiver can digitalize the audio signal and output it via the digital
balanced XLR-3M audio output G. The built-in A/D converter supports
sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz.
If you want to connect an external word clock generator instead, proceed
as follows:
왘Use a shielded 75 Ω coaxial BNC cable to connect the external word
clock generator to the BNC socket H.
왘Select “Ext.” in the “Clock” menu (see “Selecting the sampling rate for
digitalization” on page 31).
The display for external word clock synchronization B:
– lights up permanently when the digital audio output of the receiver
is synchronized with the external word clock generator,
– flashes when “Ext.” is selected in the “Clock” menu but no external
word clock generator is connected,
– flashes when the signal of the external word clock generator is
available but has not synchronized the digital audio output of the
receiver
– is off when the receiver’s internal word clock generator is used.
Notes:
– Both receivers of a twin receiver use the same word clock signal.
– The receiver has a BNC socket for word clock daisy chain output Ifor
supplying the word clock signal to further daisy chained receivers
using the supplied BNC word clock daisy chain cable. The word clock
signal is also daisy chained when a receiver is switched off.
Connecting the receivers to a PC via Ethernet
The receivers can be centrally configured and monitored via a PC and the
supplied “Wireless Systems Manager” software. Additionally, you can
update the firmware in the receivers.
To connect the receivers to a PC:
Note:
If you want to connect several receivers to the same Ethernet socket of
your network, you require a standard 100Base-T Ethernet switch.
왘Connect the supplied RJ 45 Ethernet cable to the RJ 45 socket for LAN
connection Fand to your switch or network.
왘Install the “Wireless Systems Manager” software on your PC.
왘Continue as described in the instruction manual of the “Wireless
Systems Manager” software.
The LED for LAN data transmission Elights up when data is
transmitted.
