1.2.3 Mute Button
Pressing the mute button shown in red in Figure 1‐1 fades the audio output to all channels
without disturbing the current main fader setting. Fade‐in and fade‐out speeds are
separately adjustable from 0.2 to 5 seconds, using the PC setup software. The mute button
flashes red when activated.
1.2.4 Main Fader Knob
Use this knob to adjust the sound level. A fader reading of 7.0 is the nominal correct
operating level. The main fader knob rotates continuously with no end stops. The knob is
also used to adjust parameters during setup operations.
When the fader knob is rotated between readings of 0 and 4.0, the output level changes in
20 dB steps between –90 and –10 dB. When the fader knob is rotated between readings 4.0
and 10, the output level changes in 3.33 dB steps between –10 and –10 dB. Figure 1‐3 shows
the characteristic graph.
