At the risk of creating another standard, Mackie’s compact mixers address the need of both crowds by calling things as they are — 0 dBu (0.775 V) at the output shows as 0 dB VU on the meters. What could be easier? By the way, the most wonderful thing about standards is that there are so many to choose from.
Remember, audio meters are just tools to help assure you that your levels are “in the ballpark.” You don’t have to stare at them (unless you want to).
A WORD ABOUT AUX
Sends are outputs, Returns are inputs. The AUX [30] and [31] knobs tap the signal off the channel and sends it to the AUX SEND [8] outputs. The AUX 1 signal is sent to the AUX 1 MASTER [40] knob before going
to the AUX SEND 1 output and the AUX 2 signal goes directly to the AUX SEND 2 output.
These outputs can be fed to the inputs of a reverb or other device. From there, the outputs of this external device are fed back to the mixer’s STEREO RETURN [7] jacks. Then these signals are sent through the STEREO RETURN [41] level controls, and are finally delivered to the main mix.
So, the original “dry” signals go from the channels to the main mix and the affected “wet” signals go from the STEREO RETURN to the main mix, and once mixed together, the dry and wet signals combine to create a glorious sound. So, armed with this knowledge, let’s visit the Auxiliary World:
39. PRE/POST (AUX 1)
Besides being used to work effects into your mix, Aux Sends serve another critical role — that of delivering cue mixes to stage monitors, so musicians can hear what they’re doing. On the
With the AUX 1 SELECT switch up (disengaged), AUX SEND 1 will tap a channel
With the switch down, the AUX SEND 1 becomes an ordinary effects send —

40. AUX 1 MASTER
The AUX 1 MASTER provides overall level control of AUX SEND 1, just before it’s delivered to the AUX SEND 1 [8] output. (AUX SEND 2 has no such control.) This knob goes from off (turned fully down), to unity gain at the center detent, with 10 dB of extra gain (turned fully up). As with some other level controls, you may never need the additional gain, but if you ever do, you’ll be glad you bought a Mackie.
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 suit that if the singer stuck his thumb down, you’d turn the knob down… but that never happens.)
41. STEREO RETURNS
These two controls set the overall level of effects received from STEREO RETURN [7] inputs 1 and 2. These controls are designed to handle a wide range of signal levels, from off, to unity gain at the detent, with 20 dB gain fully clockwise, to compensate for
Typically, these knobs can just live at the center detent, and the effects device’s output control should be set at whatever they call unity gain (check their manual). If that turns out to be too loud or too quiet, adjust the effects device’s outputs, not the mixer. That way, the mixer’s knobs are easy to relocate at the center detent.
