Putting the receiver into operation
10
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).
Connecting remote antennas (optional accessories)
̈
Connect two remote antennas to the BNC sockets
Positioning the remote antennas
̈
Position antennas in the same room in which the transmission takes place.
̈
Keep the distance between the receiving antennas as large as possible.

There should be a “free line of sight” between transmitter and receiving antennas.
Connecting the rod antennas to the rear of the receiver
̈
Connect the rod antennas

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.
