20 Onyx 1620i

34. –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

channel’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.

35. 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.

36. 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 [41] and control room level [40] ﬁrst, as

soloed channels may be loud.

The rude solo light [43] 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!
