Now you know how to select the signals you want to send to the engineer's control room or phones. From there, these signals all pass through the same level control: CONTROL ROOM/SUBMIX This knob controls the levels of both the stereo CONTROL ROOM outputs and PHONES outputs . The control range is from off through unity gain at the detent, with 10dB of extra gain (when turned fully clockwise). When MAIN MIX is your SOURCE selection, those signals will now pass through two level controls on the way to your control room amp and phones - the MAIN MIX knob and this CONTROL ROOM / SUBMIX knob. This way, you can send a nice healthy level to the MAIN OUTS (MAIN MIX knob at "U"), and a quiet level to the control room or phones (CONTROL ROOM / SUBMIX knob wherever you like it). When ALT 3-4 or TAPE is selected, or SOLO is engaged, CONTROL ROOM / SUBMIX knob will be the only one controlling these levels (channel controls not withstanding). Whatever your selection, you can also use the CONTROL ROOM outputs for other applications. Its sound quality is just as impeccable as the MAIN OUTS. It can be used as additional MAIN MIX output, which may sound silly since there are already three, but this one has its own level control. However, should you do something like this, be sure that you do not engage a SOLO switch, as that will interrupt your SOURCE selection. PRE-FADER SOLO (PFL) Engaging a channel's SOLO switch will cause this dramatic turn of events: Any existing SOURCE matrix selections will be replaced by the SOLO signal, appearing at the CONTROL ROOM outputs, PHONES outputs, and at the right meter. The audible SOLO levels are then controlled by the CONTROL ROOM / SUBMIX knob. The SOLO levels appearing on the right meter display are not controlled by anything - you wouldn't want that. You want to see the actual channel level on the meter display regardless of how loud you're listening. "PRE-FADER" SOLO means that the channel signal is being tapped before the channel's GAIN knob (not really a fader in this case, but we were afraid you'd laugh if we called it PreKnob Solo). It does, however, obey TRIM, LOW CUT and EQ settings, making it the perfect tool for quick inspections of suspect channels. The channel's PAN and MUTE/ALT 3-4 settings have no effect on the SOLO signal. Note: For stereo channels 5-12, the solo signal is the mono sum of the left (odd-numbered) and right (even-numbered) signals for that channel strip. WARNING: PRE-FADER SOLO taps the channel signal before the GAIN knob. If you have a channel's GAIN knob set below "U" (unity gain), SOLO won't know that, and will send a unity gain signal to the CONTROL ROOM, PHONES and meter display. That may result in a startling level boost at these outputs.
