32. –20 and OL LEDs
These LEDs indicate the channel's signal level after
the gain and EQ controls, but just before the channel's
MAIN OUT
level. So even if the level is turned down, you can see if
BAL/UNBAL
a signal is present, or if the channel is being overloaded.
The OL (overload) LED will come on when the chan-
R L R
LINE IN 7-8 LINE IN 9-10 LINE IN 11-12
nel's input signal is too high. This should be avoided, as
distortion will occur. If the OL LED comes on regularly,

check that the gain control [21] is set correctly for your

BAL/UNBAL BAL/UNBAL
input device, and that the channel EQ is not set with too

much boost.

Whenever a solo switch is engaged, you will only hear

room. This gives you the opportunity to audition the
channels before they are added to the main mix or alt

3–4 mix. You can still hear, even when the fader is down.
Solo is also used to set the gain of each channel
correctly. When a channel is soloed, you can adjust the

channel gain [21] until your input source reaches the
ALT 3/4 ALT 3/4
level of the 0 dB LED of the right meter.

For stereo channels, the mono sum of the left and

right is soloed.
7-8 9-10
Soloed channels are sent to the source mix, which
ultimately feeds your control room, phones, and meters.
Whenever solo is engaged, all source selections (main
mix, alt 3-4, tape, and FireWire) are defeated, to allow
the soloed signal to do just that—solo!
