Figure 9: Fader characteristic
1.2.3 Booth monitor speaker
With this front-panel speaker, you can monitor the audio on any active input or speaker channel. The speaker
channels are sampled prior to speaker crossovers or the LCR downmix (which mixes Le, Center, and Right
channels). The speaker channel is attenuated by 10 dB. Input sampling is not supported with macros that
support encoded audio.
The LCR downmix is the default option, which you can change in the FPUI or web UI .
1.2.4 Booth monitor speaker volume
With this smaller right-side volume knob, you can adjust the booth monitor speaker volume. The booth
monitor speaker volume defaults to the lowest setting (silent) each time you start up the system. The system
does not support automation or remote control of the booth monitor speaker fader.
1.2.5 Status indicator LEDs
There are four LEDs on the right side of the FPUI. All of these LEDs illuminate at the same time in a specific
color, depending upon the power state.
