Sennheiser EM 3732 manual Connecting the antennas to the rear of the receiver

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:

￿Slide the receiver into the 19" rack.

￿Secure the rack mount “ears” 1 to the rack using four screws (not included).

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.

￿Either use insulated antennas or

￿always mount uninsulated antennas so that they cannot come into contact with objects which conduct electricity.

The two antenna inputs R and O allow you to connect either:

ythe two supplied telescopic antennas to the rear of the receiver (see next section) or

ythe two supplied telescopic antennas to the front of the receiver (see “Mounting the antennas to the front of the rack” on page 15) or

ytwo remote antennas to the rear of the receiver (see “Mounting and connecting remote antennas” on page 16).

In addition, the receiver has two daisy chain outputs Q and P for supplying the antenna signals to further receivers (see “Daisy chaining up to eight twin receivers” on page 16).

Connecting the antennas to the rear of the receiver

The telescopic antenna 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.

￿ Connect the telescopic antennas to the BNC sockets O and R at the rear of the receiver.

￿ Align the telescopic antennas upwards in a V-shape.
