In this situation, to get out of SOLO mode you'll have to disengage all the SOLO switches, even the ones you can't hear. These eight rotary controls tap a portion of each Channel's signal, mix them together, and send them to the AUX SEND outputs outputs (or the SUB OUTPUTS if FLIP is engaged). They are off when turned fully METER Point Before: EQ IN switch (with METERING: INPUT SECTION PFL/AFL switch up), Channel Fader (with METERING: INPUT SECTION PFL/AFL switch down). down, deliver unity gain at the center detent, and provide 15dB of gain turned fully up. The AUX SEND outputs are then patched to stage monitor amp inputs (pre-Fader) or parallel effects processor inputs (post-Fader).

We have found You may already be an expert in the world that most "stereo" reverbs' second input just ties of "+4" (+4dBu=1.23V) and "-10" up an extra aux send and adds nothing to the (-10dBV=0.32V) operating levels. Basically, sound. There are exceptions, so try it both ways. what makes a mixer one or the other is the relative 0dB VU (or 0VU) chosen for the PRE switch (AUX 1-4) Meters. A "+4" mixer, with a +4dBu signal Point Before: Channel Fader (switch up), pouring out the back, will actually read 0VU on HPF (switch down). the Meters. A "-10" mixer, with a -10dBV signal trickling out, will also read 0VU on its Meters. So when does 0VU actually equal 0dBu? Right now! At the risk of creating another standard, Mackie has done away with the two standards just mentioned in favor of a simpler one: 0dBu at the output equals 0VU 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.) Point After: AUX sends 1-4 . This switch determines the tap point of AUX sends 1-4. Generally, post sends are used to feed effects devices, and pre sends are used to feed your stage monitors. In post mode (switch up), AUX sends 1-4 will follow the EQ, HPF, Fader and MUTE settings. If you fade the Channel, you fade the AUX send. This is a must for effects sends, since you want the levels of your "wet" signals to follow the level of the "dry" signal. In PRE mode (switch down), AUX sends 1-4 follow the TRIM, 0/ (polarity), HPF and MUTE settings only.
