User manual MACKIE ONXY-1620

[. . . ] OWNER'S MANUAL ONYX 1620 Important Safety Instructions 1. Install in accordance with the manufacturer's instructions. 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 nothing is selected in the CONTROL ROOM/ PHONES SOURCE matrix (20) and no channels are in SOLO, the meters won't do anything. RUDE SOLO Light This large green LED flashes on and off when a channel's solo is active, as an additional reminder beyond the indicating LEDs next to each SOLO button. If you work on a mixer that has a solo function with no indicator lights and you happen to forget you're in solo mode, you can easily be tricked into thinking that something is wrong with your mixer. It's especially handy at about 3 am when no sound is coming out of your monitors but your multitrack is playing back like mad. Owner's Manual 15 ONYX 1620 Auxiliary Section This section includes the AUX MASTERS (Sends) and the AUX RETURNS. These can be a bit confusing to the uninitiated, so here's the whole idea behind aux sends and returns: sends are outputs and returns are inputs. AUX SENDs tap signals off the channels, via the AUX knobs (14), mix these signals together, then send them out the AUX SEND jacks (50). 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 (51). Then these signals are sent through the AUX RETURN level controls (30), and finally delivered to the MAIN MIX (38). 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!The AUX SENDS can also be used to provide another mix for stage monitors, for example. In this case, the AUX RETURNS aren't used to return the signal. Instead, they can be used as additional stereo inputs. 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. Most other mixing consoles require you to assign the pre/post function in pairs (Aux 1/2, Aux 3/4), which can be very limiting if you want to provide three monitor sends and one effects send, for example. The Onyx 1620 allows you to assign the pre/post function for each AUX SEND individually. Both pre- and post-fader sends are affected by the EQ controls (unless the EQ is bypassed, of course). 30. AUX 1-4 RETURNS These four controls set the overall level of effects received from the stereo AUX RETURN 1-4 inputs (51). These controls range from off () to +10 dB of gain when fully clockwise, to compensate for low-level effects. Signals passing through the AUX RETURN level controls proceed directly to the MAIN MIX bus where they are combined with the other channels just before the MAIN MIX fader (38). 31. FX TO MON Switch This switch routes the signal from AUX RETURN 3 to the AUX 1 SEND instead of the MAIN MIX bus.
