20.3 AV Integration (Unity Gain)
The Unity Gain function enables an audio-visual processor to be
integrated with the NAIT 5i such that its volume control takes
over command of signals connected the amplifier’s AV input.
To select unity gain, first switch the NAIT 5i into program
mode as described in Paragraph 20.2. The AV input button will
illuminate if unity gain is already enabled. If it is not enabled
it can be activated by pressing the handset 4 key or the front
panel AV button. Deselect unity gain by again pressing the 4
key or the AV button. Unity gain only becomes operational or is
cancelled on exiting from program mode by pressing and holding
the handset prog key or front panel cd button.
Note: The unity gain feature must be used with care. It effectively
by-passes the NAIT 5i volume control leaving any signal connected
to the unity gain input to be passed to the power amplifier and
speakers at full volume. Additionally, if an input is selected which
has unity gain enabled, the volume handset functions will be
disabled and their indicators will turn off. This will be flagged by the
volume indicator flashing if its handset keys are used.
