In a nutshell, soloed channels are sent to the SOURCE [42] mix, that ultimately feeds your control room, headphones, and meters. Whenever SOLO is engaged, all SOURCE selections (MAIN MIX, 1­2, 3­4 and TAPE) are defeated, to allow the soloed channel to do just that -- SOLO! 30. MUTE Engaging a channel's MUTE switch provides the same results as turning the fader all the way down: Any channel assignment to L/R, 1-2 or 3-4 will be interrupted. All the post AUX sends will be silenced, as will the DIRECT OUT [5] signals on channels 1 through 8. And of course, that fun-loving OL (MUTE) LED [29] will commence to glow. The PRE AUX sends, channel INSERT [4] send and SOLO [27] (in LEVEL SET (PFL) mode) will continue to function during MUTE. Depending on the audio content in a channel, engaging its MUTE switch may cause a slight popping sound. This is not a problem within the mixer, and it can be avoided: Simply engage the LOW CUT [34] switch on each channel (unless its low frequency content is vitally important, such as a kick drum or bass guitar). LOW CUT eliminates subsonic debris, which causes the pop, and its effect is usually transparent. Owner's Manual 28. ­20 (SOLO) LED An LED that does two completely different things!This saves space, but requires some explanation. First, the "­20" part: Often referred to as "signal activity, " this LED will flicker in time with the signal present in that channel. It's handy for confirming that a channel is indeed active, and may also lend a clue as to what the signal is. For instance, a kick drum will cause the LED to pulse in time with the drum, and a synth pad will cause it to glow a bit more steadily. Now for the "SOLO" part: When a channel's SOLO [27] switch is engaged, this LED will glow steadily. It will also be brighter than it would be as a ­20 indicator. In conjunction with the RUDE SOLO LIGHT [47], you can find a rogue SOLO switch very quickly. 31. PAN PAN adjusts the amount of channel signal sent to the left versus the right outputs. PAN determines the fate of the L/R assignment, subgroups 1­2 and 3­4, and the SOLO [27] (in NORMAL (AFL) mode). With the PAN knob hard left, the channel signal will feed the left main mix, subgroup 1, subgroup 3 and left NORMAL (AFL) solo mode (assuming their assignment switches are engaged). With the knob hard right, the channel signal feeds the right main mix, subgroup 2, subgroup 4 and right NORMAL (AFL) solo mode. [. . . ] Here's how it works: A mono signal should be patched into the input or return jack labeled Left (MONO). The signal will be routed to both the left and right sides of the return circuit, and will show up in the center of the stereo pair of buses it's assigned to, or it can be panned with the PAN control.
