active CUT is displayed by LED

1 Stereo AUX send (AUX 3/4) with rotary pots for level and pan with CUT function by push/pull switch of the level control and LED, pan pot and pre/post switch.

Main Fader
Brand Penny & Giles VCA fader with 126.5 mm travel,maximum gain 15 dB, 0 dB point manually adjusted
Cut off attenuation according to German 'IRT-Pflichtenheft 3/5' Scale accuracy according to German 'IRT-Pflichtenheft 3/5'
Additional CUT function.

PFL and Peak-Present Indicator
PFL by illuminated switch. The pre fader listen is latched if the fader is closed and resets when the fader is opened. If the fader is open, non latched operation is possible.
The Peak-Present-Indicator is a 3 color LED and displays the level at the fader input. Green: level above - 20 dB, yellow: 0 dB and red if the headroom is below 5 dB

Panoramic Section
4-Channel Panoramic Control for @Dolby-Surround,with LCR-Pan, Front-Surround-Pan and Divergence control. The panoramic section is affected by the central operation mode setting. With mono operation no pan pot is inserted. With stereo mode the LCR pan operates as a normal L/R control with 3 dB attenuation at the center position.

Group Buss Selection
4 switches for the selection of the 4 groups, functions depend on the operation mode setting.
Mono: independend operation of all switches.
Stereo: 1 & 2 and 3 & 4 are coupled to select stereo masters.
Surround: any switch selects the entire 4 channel master.
