Any input or output can be monitored pre (PFL) or after level control (AFL), as desired. The system may be additive (all channels selected on solo bus), or exclusive, so that only one solo switch is active at a time ("last pressed"). Any signal being solo'd appears on the dedicated left and right solo meters, and is audible in the stereo headphone system and the Monitor outputs (unless the SOLO OFF button is pressed). Solo functions may be canceled by tapping any illuminated solo switch, or all solo switches may simultaneously be canceled using the Solo Clear switch. Solo Control This covers the Solo Control features located in the Master section post fader switch Any input or output signal that is solo'd can be be derived before or after it's main level control. In the case of Input channels this would be the channel fader and in the case of outputs this would be the output fader or rotary pot. Pre fader - Any input or output signal that is solo'd will be derived before it's main level control. Post fader - Any input or output signal that is solo'd will be derived after it's main level control. additive / last press pressed switch The solo system has two modes - ADDITIVE and LAST PRESSED. Additive - Multiple inputs/outputs can be solo'd at once. After soloing one input or output, pressing subsequent channel solo switches will continue to add channels to the solo bus. Pressing any solo button that is already activated will deactivate that solo. Last Pressed - Only one solo can be activated at a time. Pressing another solo button will clear the previous solo. solo active / clear switch This momentary, illuminated switch provides two functions. Solo active - When any input/ouput on the console is solo'd, this switch it lit up. Clear - Pressing this switch will clear (shut off) any inputs/outputs on the console that are solo'd. This is especially useful when the solo system is in Additive mode, to clear multiple soloes with one button press. p. 83 5 master control section A ROL) ORS X-VCA owner's manual HPF HI-PASS FILTERS 40HZ@24DB/OCT GC RIGHT SIDE FOLLOWS LEFT L/R PRE-FADER +10 RIGHT FADER RIGHT POST L / R TO MONO LEFT POST LEVEL FREQ LEVEL FREQ LEVEL FREQ LEVEL FREQ LEVEL FREQ TB FEED TALK TO MONO RIGHT POST MONO INSERT SEND RTN Q 3 - 0. 7 Q 3 - 0. 7 Q 3 - 0. 7 TO SOLO BUS & MICRO INTERFACE MONO SOLO HI-PASS FILTER 40HZ@24DB/OCT MONO MIX MONO EQ ON MIX AMP HPF ON HPF GC MONO POST HF 1K - 20 KHZ HI MID 400 - 8 KHZ MID 200 - 4 KHZ LO MID 60 - 1. 2KHZ LF 40 - 800HZ +10 MONO FADER MONO PRE-FADER 5-BAND SEMI-PARAMETRIC EQ PK SOLO LEFT SOLO RIGHT M1 M2 M3 M4 MONO MATRIX SENDS POST MONO SIG MONO TO MATRIX SENDS SHOWN.
