Analog Gain
Displays the gain reduction set in the rear panel gain control on each loudspeaker. The gain can be adjusted
in the range (-20dB÷0dB).
Mute
This parameter can mute or un-mute the input channel.
0°/180°
Changes the polarity of the channel, i.e. this parameter reverses the phase of the signal.
Meter
Displays the level of the audio signal. It reads the level of the signal just after the level and mute controls.
Note: the clip LED indication checks the input signal both before the level controls and after the level controls
so it can detect if a clip occurs also in a muted device.
7.1.2 Input Delay
Fig.73 Input delay parameters.
Value
Delay value.
Unit
Unit of measurement for the delay. Note that selecting unit of measurement for length (mm, m, inch, feet,...)
the amount of delay (distance value) depends on the air temperature as indicated in the “environmental
settings” (see “Global page”).
