[. . . ] The stereo channel AUX knobs control a mono sum of the channel's stereo signals. For example, on the DFX·12, channel 9 (L) and 10 (R) mix together to feed that the channel 9/10 AUX knobs. The master AUX SEND (38, 41) knobs adjust the overall aux output levels. These are more than mere effects and monitor sends: they can be used to generate separate mixes for recording or "mix-minuses" for broadcast. the center position, the left and right channel signals pass through to the main mix unaffected. If PAN is turned left, the right channel is attenuated; if turned right, the left side is attenuated. LEVEL SET 11/12 U 24. MUTE When you engage a channel's MUTE switch, its signal disappears from the main mix, tape, AUX 1, AUX 2 and headphones. The only exception is the INSERT (4) outputs. -20dB +20dB GAIN U EQ HI 12k 25. FADER This fader is the master level control for the channel's signal. Subtle adjustment of the channels' fader positions is the key to a finelytuned mix. Typically (providing the GAIN (16) control is set correctly) the fader position will be positioned somewhere between 0 dB ("U") and ­30 dB. If you have a fader set all the way up, that's usually a sign that your GAIN is set too low. Conversely, if the fader is set way down, your GAIN may be set too high. -15 +15 U LOW 80Hz -15 +15 AUX U O O 1 MON +6 U O O 2 EFX 21. AUX 1/MON AUX 1 is designed for feeding a separate monitor mix to the musicians on stage, via the AUX 1 SEND (7) output jack. The signal is tapped off before the channel EQ section, and before the channel fader. Only the channel GAIN, MUTE and LOW CUT will affect the output to your monitors. +6 "U" = UNITY GAIN Mackie mixers have a "U" mark on almost every level control. This stands for "unity gain, " meaning there is no change in signal level. Once you have adjusted the input signal to line-level, you can set every control at "U" and your signals will travel through the mixer at optimal levels. What's more, all the labels on our level controls are measured in dog biscuits (dB), so you'll know what you're doing level-wise if you choose to change a control's settings. L R PAN 11/12 MUTE dB 22. AUX 2/EFX AUX 2 is designed for feeding the EMAC internal effects processor and the inputs of parallel effects devices. It is post-fader, so any changes to the channel controls will affect the AUX 2 signal. In addition to feeding the inputs of the EMAC, it also feeds the AUX 2 SEND (8) output. 10 OL 5 U 5 10 20 30 40 50 60 O O 26. OL (OVERLOAD) LED This handy feature gives you the chance to take care of any signal overload before it is made worse by turning up the fader. [. . . ] For example, if a left output is presumed dead, switch the left and right cords, at the mixer end. If the left speaker is still dead, it's not the mixer. Noise · Turn the channel Faders , AUX RETURN and AUX SEND controls down, one by one. If the sound disappears, it's either that channel or whatever is plugged into it, so unplug whatever that is. Power · Our favorite question: Is the POWER switch on?· If the POWER LED is blinking, switch the mixer off for a few seconds, and disconnect all connections except the linecord. [. . . ]
