7. Operation
1. Pull out both antennas and place them perpendicular to the receiver.
2. Connect the receiver to the sound system:
OUT MIX: Use an appropriate audio cable to connect to the amplifier or mixing table.
o
BALANCE OUT: Use an appropriate audio cable to connect to the amplifier or mixing table.
o
3. Make sure the volume level is at its minimum and switch on the receiver.
4. Switch on the microphone.
5. Adjust the volume to a moderate level.

Cleaning and Maintenance


All screws should be tightened and free of corrosion.

The housing, visible parts, mounting supports and the installation location (e.g. ceiling, suspension,
trussing) should not be deformed, modified or tampered with; e.g. do not drill extra holes in
mounting supports, do not change the location of the connections...

The electric power supply cables must not show any damage. Have a qualified technician maintain
the device.

