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
level. So even if the level is turned down, you can see if
a signal is present, or if the channel is being overloaded.
The OL (overload) LED will come on when the chan-
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
input device, and that the channel EQ is not set with too
much boost.
The –20 LED comes on when the channel signal
strength has reached that level.
33. 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 [21] is set correctly.
34. SOLO
Whenever a solo switch is engaged, you will only hear
the soloed channel(s) in the headphones and control
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
level of the 0 dB LED of the right meter.
Solo signals reaching the headphones and
control room are not affected by the channel
level or main level; therefore, turn down the
phones level [39] and control room level [38] first, as
soloed channels may be loud.
The rude solo light [41] will turn on as a reminder
that what you are listening to in the headphones and
control room is just the soloed channel(s).
For stereo channels, the mono sum of the left and
right is soloed.
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!
