6.1.3 Connecting other external audio sources

The transmitter has up to 32 audio inputs (depending on the transmitter type) to interface

with external asymmetrical audio sources, such as congress systems from other

manufacturers or for music distribution. The audio signals (stereo or mono) are connected to

the audio input cinch connectors.

6.1.4 Connecting an emergency signal

To use the emergency signal function, a switch (normally-open) must be connected to the

emergency switch connector. The reaction of the transmitter on a closed switch depends on

the configuration of the auxiliary inputs (see also section 7.2.9 ):

– If the auxiliary input is 'Mono + Emergency', the audio signal on the Aux-Right input is

distributed to all output channels, overriding all other audio inputs.

– If the auxiliary input is 'Stereo' or 'Stereo to Mono', the audio signals on the Aux-Left and

Aux-Right inputs are distributed to all output channels, overriding all other audio inputs.

NOTICE!

When the cinch audio inputs are used in combination with inputs via one of the interface

modules, the signals on corresponding channels are mixed. This situation should normally be

avoided by using higher-numbered cinch audio inputs.
