- RESTAURANT SYSTEM
This two tiered priority ducking example allows for background music to be present on channel 3, which can be
overridden by the presence of audio on channel 2 from a TV signal, both of which can be overridden by a
keyed microphone announcement on channel 1. Stereo audio signals using RCA jacks are summed to mono at
the input.
In this example, all three inputs are assigned to Zone 2 via the DIP switches. Because the mic is set up for push-
to-talk, the IN 1 VOX trigger switch is left off. IN 2 VOX trigger is switched on however, so that signal from the
TV will automatically override the background music. Mute Link is switched on so that the keyed mic will mute
both Inputs 1 and 2.
A 70V distributed speaker system runs off of the main power amplifier, and an external amplifier is run off of
the Zone 2 600
Ω
output. A small 1W 8
Ω
speaker is run off of the Zone 2 Low Z output.
