2.5.13 Configure auxiliary inputs
The way the signals on the auxiliary inputs (Aux-.L and Aux.-R) are handled can be set in the Aux. Input Mode menu (4H).
When the option 'Stereo' is chosen, the signals on both Aux. inputs are distributed as a stereo signal to all channels. This setting
can for instance be used to transmit a music signal during breaks in a conference. Note that the Transmission mode must be set
to 'Aux to All' (menu item 4A) to actually transmit this stereo signal.
The 'Stereo to Mono' and ‘Mono+ Emergency’ options can be selected when the transmitter is used in combination with an
interpretation system. The Aux. input(s) will be distributed to the Symmetrical Audio Input and Interpreters Module. In this
configuration the 'floor' signal should be connected to the Aux. inputs.
