1. Mains on/off switch - After switching the mains on, the transmitter starts up and the display (3) will light-up.
2. Mini IR-radiator – Four IREDs, transmitting the same infra-red signal as the radiator output. This can be used for
monitoring purposes. They can be disabled via the configuration menu.
3. Menu display – A 2x16 character LCD-display gives information about the transmitter status. It is also used as a an
interactive display for configuring the system.
4. Menu button – A turn-and-push button to operate the configuration software in combination with the display (3).
5. Monitoring headphone output – A 3.5 mm (0.14 inch) jack socket to connect a headphone for monitoring purposes. It

Figure 2.3 Transmitter, rear view
1. Interface module slot- An optional audio interface module can be mounted in the transmitter housing. Its connectors are
accessible via an opening at the back of the transmitter.
2. Emergency switch connector – A terminal block socket for a single, 'normally open' switch. When the switch is closed,
the audio signal on the Aux-right input is distributed on all output channels, overriding all other audio inputs. A matching
cable connector is provided.
3. Auxiliary audio inputs – Two female XLR connectors for extra audio inputs. They can be used to connect auxiliary
symmetrical audio signals such as a music installation, the floor language or emergency messages.
4. Audio signal inputs – 4, 8, 16 or 32 cinch plugs to connect external asymmetrical audio input signals. The number of
connectors depends on the transmitter type.
5. Earth connection point - Only used for factory testing purposes.
6. Radiator signal loop-through input – A HF BNC connector to loop-through the radiator output of another transmitter.
7. Radiator signal outputs – Four HF BNC connectors, used to connect the radiators. Up to 30 radiators can be loop-
through connected to each output.
8. Mains input – Euro mains socket. The transmitter has automatic mains voltage selection. A mains cable is provided.
