AUX FX These knobs tap a portion of each channel's signal to set up a nice FX mix feeding the internal FX processor, and to feed external processors via the FX output [13]. The aux FX feed from hybrid and stereo channels is a mono sum of the left and right sides of these channels. The controls are off when turned fully down, deliver unity gain at the center detent, and can provide up to 15 dB of gain turned fully up. The channel fader [30], mute [29] and other channel controls affect the FX output, but pan [27] does not. (The aux FX is post-fader.) The FX signal reaching the internal FX processor and the FX send output jack, is the sum (mix) of all the channels whose aux FX control is set to more than minimum. The overall FX send level may be adjusted with the FX master knob [51]. The FX signal from the internal FX processor is added to the main mix using the FX return fader [45], and may be added to the monitors with the FX to mon knob [53]. 27. PAN These knobs adjust the amount of channel signal sent to the left versus the right outputs. On mono channels these controls act as pan pots. On h­ ybrid and stereo channels, they work like the balance control on a home stereo. They do not affect the aux mon or FX mixes. 28. OL LED This LED will light if the channel signal is too high, and this may cause distortion due to overloading. The OL LED comes before the channel fader [30] in the signal path, so the fader has no effect in your efforts to turn off the OL LED. Overloading may occur if the gain [19] is set too high, so check that the level set LED [20] is not turning on frequently. Turn down the gain if it is. Overloading may also occur if the channel EQ [22-24] is set too high. Check that the EQ settings are moderate. Use the low cut switches [21] if the overloading is due to lower unwanted bass thumps and bangs. 29. MUTE Press this switch in to mute the channel in the main mix. The aux mon output of the channel is not muted, but the FX output to the internal FX processor and FX send jack [13] is. 30. CHANNEL FADER These faders control the channel's level from off, to unity gain, on up to 10 dB of additional gain. The mono channels have mono faders, and the hybrid and stereo channels use stereo faders. With the gain control [19] set correctly, the faders should be set around unity gain (U). 20 ProFX8 and ProFX12
