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! 20 Onyx 1620i
