PFL SOLO Switch When a channel's solo switch is engaged, any existing selection is replaced by the solo signal, appearing at the control room outputs [31], phones [33] and at the left meter [40]. The audible solo levels are then controlled by the control room knob [53]. The solo levels appearing on the meters are not controlled by the control room knob [53] - you would not want that, anyway. What you do want to see is the actual channel level on the meters regardless of how loud the control room and phones output levels might be. PFL means Pre-Fader Listen (post-EQ). With the PFL Solo switch engaged, solo will not be affected by a channel's mute switch [20] position. Remember, PFL taps the channel signal before the fader. If you have a channel's fader set way below "U" (unity gain), solo will not know that and will send a unity gain signal to the C-R outs [31], phones output [33] and meter display [40], which may raise some eyebrows. 23. CHANNEL FADER This is the last control in a channel's signal path, and it adjusts the level of each channel onto the main mix. The "U" mark i­ndicates unity gain, meaning no increase or decrease of signal level. All the way up provides an additional 10 dB, should you need to boost a section of a song. If you find that the overall level is too quiet or too loud with the level near unity, check that the gain control [9] is set correctly. 24. USB Switch The USB switch on the last stereo channel provides stereo playback of iTunes®, or a DAW via the USB connection. Like any other input, this signal may also be EQ'd, sent to an aux bus, or mixed in with the other signals and assigned to subgroups or main outs. This switch overrides the TRS inputs [6, 7].
