User manual MACKIE ONYX 1640

[. . . ] OWNER'S MANUAL ONYX 1640 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. [. . . ] 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 1640 allows you to assign the pre/post function for each AUX SEND individually!Both pre- and post-fader sends are affected by the MUTE button and the EQ controls (unless the EQ is bypassed, of course).

AUX 1 -6 MASTERS The AUX MASTERS provide overall control over the AUX SEND levels, just before they are delivered to the AUX SEND outputs [62]. 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. ) O O +15 +10 O O +10 TO AUX 6 O O +15 MON 3 SOLO PRE POST O O +10 SEND TO O O +15 MON 4 O O MAIN SUBS SOLO PRE POST MON +10 36.

AUX SENDS SOLO AUX MASTERS AUX SENDS AUX RETURNS PRE POST MON O O EFX TO MON This button allows you to solo an individual AUX SEND. If you are using the aux sends to feed your stage monitors, you can use these buttons to check your monitor mix. Beside each switch is an indicating LED to let you easily spot a soloed aux send. The aux send solo is not affected by the SOLO MODE switch (PFL/AFL), except that in PFL mode only the right meter indicates the signal. The aux send's PFL/ AFL status is determined by the PRE/POST switches next to the AUX SEND MASTERS. 1 2 3 4 5 6 1 O O +15 SOLO PRE POST MON +10 O O +10 TO AUX 5 2 SOLO PRE POST O O O O +15 +10 O O +10 TO AUX 6 O O +15 MON 3 SOLO PRE POST O O 38. AUX 1-4 RETURNS SEND TO +10 O O +15 MON 4 O O MAIN SUBS These four controls set the overall level of effects received from the stereo AUX RETURN 1-4 inputs [61]. 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]. SOLO PRE POST MON +10 O O +15 SOLO PRE POST MON CR/ PHONES ONLY SUBS 1-2 3-4 39. AUX RETURN 4 to CR/PHONES ONLY When this button is up, AUX RETURN 4 is routed to the MAIN MIX bus, just as the AUX RETURNS 1-3 are. When the button is down, the AUX RETURN 4 stereo signal is routed to the CR/PHONES matrix instead. It doesn't matter if any of the SOURCE buttons are assigned, but it will be interrupted, as usual, if a SOLO button is engaged. Let's pretend you're doing a live mix to a 2-track deck, a house PA, or both, and you want to play along to a click track. You could run the click track directly into the MAIN MIX, but you don't want the mixdown deck or the audience to hear it. Oh yeah, you can route it to the control room and phones output instead!
