Main Mix XLR MAIN OUTPUTS The male XLR output connectors provide a balanced line-level signal that represents the end of the mixer chain, where your fully mixed stereo main mix signals enter the real world. Connect these outputs to the inputs of your main power amplifiers, powered speakers, or serial effects processor (or a graphic equalizer or compressor/limiter). The output provides a fully balanced signal playing the same program material as the 1/4" TRS main outs. MAIN MIX and FIREWIRE The main mix can be sent to your computer via two dedicated Firewire signals. The output is not affected by the main mix fader, allowing you to record the main mix of live performances. The left main mix will appear on FireWire output channel 15, and the right on channel 16. In addition to recording the main mix using FireWire, you can record individual channels using FireWire, for studio mixing at a later date. See page 15. MAIN OUTPUT LEVEL (+4 dB/MIC) When this recessed switch is out (+4 dB), the XLR main outputs provide a "+4 dBu" line-level signal. You can then connect these outputs to the line-level inputs of power amplifiers, powered loudspeakers, or serial processors. In a studio setting, you could connect the main mix to the inputs of a professional stereo recorder. TAPE OUT This RCA unbalanced output is a copy of the main mix (post fader). You can use it to record the main mix on an analog tape deck for example. When the switch is pushed in (mic), the XLR main outputs are attenuated to microphone level. You can then connect these outputs safely to the microphone inputs of another mixer, providing a submix for keyboards or drums, for example, in a live sound application. The main outputs can then be plugged directly into a stage snake, and appear back at the front of house console like any other microphone level source.

The switch is recessed, to reduce the chance of accidently turning it on or off when plugging things in. XLR Main Outputs Main Output Level +4dB/Mic 1/4" TRS Main Outputs Tape Out 1/4" TRS MAIN OUTPUTS These 1/4" TRS output connectors provide the balanced or unbalanced line-level output of the main mix. This is the same signal that appears at the XLR main outputs, except it is not affected by the main output level switch. MAIN MIX FADER This is the main stereo fader that adjusts the level of the XLR and 1/4" main outputs, and the tape output. It does not affect the FireWire output of the main mix. If the gain of each channel has been set up correctly for all your microphones, line-level sources, guitars, and so on, then these channels can be added to the main mix by careful adjustment of the channel faders. The main mix fader is then used to turn the complete main mix level up and down. 1 ONYX MIC PRE 2 ONYX MIC PRE 3 ONYX MIC PRE 4 ONYX MIC PRE CTRL - RM OUT BAL/UNBAL MAIN OUT BAL/UNBAL ALT 3-4 OUT BAL/UNBAL L R L R L/3 R/4 LINE IN 5-6 LINE IN 7-8 LINE IN 9-10 LINE IN 11-12 TAPE L IN OUT R 1 LINE BAL/UNBAL LINE HI-Z 48V 2 LINE BAL/UNBAL LINE HI-Z 3 LINE BAL/UNBAL 75Hz 18dB/OCT 4 LINE BAL/UNBAL 75Hz 18dB/OCT 48V 48V 48V L (MONO) BAL/UNBAL R L (MONO) BAL/UNBAL R L (MONO) BAL/UNBAL R L (MONO) BAL/UNBAL R PREMIUM ANALOG MIXER w/ PERKINS EQ & FIREWIRE 30 U 20 40 GAIN U 60 -20dB +40dB 30 U 20 40 GAIN U 60 -20dB +40dB 30 U 20 40 GAIN U 60 -20dB +40dB 30 U 20 40 GAIN U 60 -20dB +40dB U GAIN -20dB +20dB U GAIN -20dB +20dB U GAIN -20dB +20dB U GAIN -20dB +20dB SEND PRE POST U EQ -15 +15 1k HIGH 12kHz SEND PRE POST U EQ -15 +15 1k HIGH 12kHz SEND PRE POST U EQ -15 +15 1k HIGH 12kHz SEND PRE POST U EQ -15 +15 1k HIGH 12kHz SEND PRE POST U EQ HIGH 12kHz -15 +15 SEND PRE POST U EQ HIGH 12kHz -15 +15 SEND PRE POST U EQ HIGH 12kHz -15 +15 SEND INPUT LINE U FW 1-2 HIGH 12kHz -15 +15 FREQ 100 8k U MID -15 +15 U LOW 80Hz -15 +15 AUX FREQ 100 8k U MID -15 +15 U LOW 80Hz -15 +15 AUX FREQ 100 8k U MID -15 +15 U LOW 80Hz -15 +15 AUX FREQ 100 8k U MID -15 +15 U LOW 80Hz -15 +15 AUX U MID 2.5kHz -15 +15 U LOW 80Hz -15 +15 AUX U MID 2.5kHz -15 +15 U LOW 80Hz -15 +15 AUX U MID 2.5kHz -15 +15 U LOW 80Hz -15 +15 AUX U MID 2.5kHz -15 +15 U LOW 80Hz -15 +15 AUX CTRL ROOM/PHONES SOURCE MAIN MIX TAPE FW 1-2 ALT 3-4 ASSIGN TO MAIN MIX OO MAX CONTROL ROOM OO MAX PHONES 0dB=0dBu LR 20 CLIP 15 10 6 3 0 2 LEVEL 4 SET 7 10 20 30 RUDE SOLO AUX MASTER SEND RETURN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX 2 MAX PAN OO OO 1 MAX PRE POST 2 MAX PAN PRE POST OO OO 1 +15 RTN TO AUX1 2 +15 OO OO 1 +10 2 +10 L R L R L R L R L R L R L R L R POWER MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 MUTE ALT 3/4 dB dB dB dB dB dB dB dB MIC dB 10 10 10 10 10 10 10 10 10 5 5 5 5 5 5 5 5 5 U U U U U U U U U OL OL OL OL OL OL OL OL 5 - 20 5 - 20 5 - 20 5 - 20 5 - 20 5 - 20 5 - 20 5 - 20 OO MAX LEVEL 5 10 10 10 10 10 10 10 10 10 DESTINATION 20 20 20 20 20 20 20 20 20 30 30 30 30 30 30 30 30 30 40 50 40 50 40 50 40 50 40 50 40 50 40 50 40 50 PHONES AUX 1-2 40 50 60 60 60 60 60 60 60 60 60 OO OO OO OO OO OO OO OO OO SOLO 1 SOLO 2 SOLO 3 SOLO 4 SOLO SOLO SOLO SOLO 5-6 7-8 9-10 11-12 TALKBACK TALKBACK MAIN MIX Main Mix Fader 12 Onyx 1220i
