Description of Controls
Channel PAN
The PAN sends the output of the Channel in continuously variable degrees to either side of the stereo mix (if L-R switch is pressed -- see below), or to odd-even sides of the Group Assignment switches (pan left for Groups 1, 3, 5 and 7; pan right for Groups 2, 4, 6 and 8). The PAN control is a combination “where to/how much” control, in that it controls both the level and direction of a signal.
Channel PEAK LED
The PEAK LED will flash when the Channel’s signal level (post-EQ, pre-insert, pre- fader) is 15 dB over nominal level. This is 3 dB before the channel electronics will distort. If it flashes, reduce the MIC/LINE GAIN knob (or the gain of any device at the INSERT jack) until it stops flashing.
Channel SOLO Button
The SOLO button sends the Channel’s pre-fader signal (and only that Channel’s signal, if no other SOLO buttons are pressed) directly to the Control Room monitors, cutting off any other signals to the Control Room. It allows the engineer to hear the signal before bringing it into the mix, for cueing purposes. When SOLO is pressed, its LED will light. The master SOLO LED will light in the Master module section, to alert you that Solo is active. You can adjust the output level of the signal(s) being soloed by turning the SOLO knob in the Master module section.
Channel MUTE Button
The MUTE button disconnects the Channel’s signal from the Master outputs, the Group outputs, and any post Aux Sends. When pressed, the MUTE button’s LED will light. This can be controlled via the Dynamic Mute Automation system, which gives it other functions as well (see Chapter 5).
DIR Switch
The DIR switch determines what signal appears at the TAPE OUT jacks (both ELCO balanced and 1/4" unbalanced). When the DIR switch is up, the TAPE OUT signal will be the corresponding Group signal (Group 1 on Channels 1, 9, and 17; Group 2 on Channels 2, 10 and 18; etc.). When this switch is down, the TAPE OUT signal will be the direct output of the selected channel (post-fader).
JBe very careful when both the DIR switch and CHAN/MON REVERSE switches are down. If you arm the tape track on that channel for recording, (or do anything else where the tape machine monitors its input) feedback will occur.
Group Assign Switches (1–2, 3–4, 5–6, 7–8)
The Group Assign switches (1-2, 3-4, 5-6, and 7-8) assign the output of the Channel (large fader) to any of the eight Group output busses. Each Group Assign switch is an odd-even pair, and the amount of signal sent to odd or even numbered groups is determined by the Channel PAN knob. These may be used in any combination.
