[. . . ] OWNER'S MANUAL ONYX 1220 Important Safety Instructions 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] AUX SENDs tap signals off the channels, via the AUX knobs (13/14), mix these signals together, then send them out the AUX SEND jacks (38). These outputs are fed to the inputs of an external processor like a reverb or digital delay. From there, the outputs of this external device are fed back to the mixer's AUX RETURN jacks (39). Then these signals are sent through the AUX RETURN level controls (28), and finally delivered to the MAIN MIX (36). So, the original "dry" signals go from the channels to the MAIN MIX and the affected "wet" signals go from the AUX RETURNS to the MAIN MIX, and once mixed together, the dry and wet signals combine to create a glorious sound!They can also be used to provide another mix for stage monitors, for example. Instead, they can be used as additional stereo inputs. Owner's Manual 15 ONYX 1220 26. AUX 1 and AUX 2 MASTER The AUX MASTERS provide overall control over the AUX SEND levels, just before they are delivered to the AUX SEND outputs (38). This is usually the knob you turn up when the lead singer glares at you, points at his stage monitor, and sticks his thumb up in the air. (It would follow that if the singer stuck his thumb down, you'd turn the knob down, but that never happens. ) TALKBACK Section The talkback feature allows the engineer to communicate with the talent either through the PHONES outputs (42) or the AUX 1-2 outputs (38). A talkback microphone is built into the Onyx 1220, or you have the option of connecting an external microphone at the TALKBACK MIC XLR connector (45) on the rear panel, which may be preferable in live or noisy situations. 30. Internal TALKBACK MIC This is where the built-in talkback microphone is located. This is an omni-directional dynamic microphone, so it will pick up your voice from anywhere in front of the mixer. 27. AUX 1 and 2 PRE/POST The PRE/POST switches determine whether the AUX SEND signal is tapped from the channel before the fader (pre-fader) or after the fader and MUTE button (postfader). Typically, you use a pre-fader send for monitors so you can control the monitor levels independently from the MAIN MIX. Use a post-fader send for effects, so that the "wet" signal level follows the "dry" signal level. Both pre- and post-fader sends are affected by the EQ controls (unless the EQ is bypassed, of course). FADER PAN MUTE / ALT 31. TALKBACK LEVEL Use this knob to control the level of the talkback signal being routed to the PHONES or AUX 1-2 outputs. This controls the talkback level for either the internal or external TALKBACK MICs. You should start with the TALKBACK LEVEL control turned down, and then slowly turn it up until you get confirmation from whoever is listening to headphones or monitors that they can hear you. Once you have set the level, you can leave it there for the duration of the session (or the gig).
