Channel Controls
The 10 vertical channel strips look very similar, and
have a only few differences between them. Each chan-
nel works independently, and just controls the signals
plugged into the inputs directly above it.
Mono Channels 1 to 8
• Channels 1 to 8 are mono channels, and their
controls affect either the mono mic input or the
mono line-level input.
• Channels 1 to 6 each have an internal signal in-
line compressor circuit with adjustable thresh-
old.
• Channels 7 and 8 each have a hi-z switch, so
you can connect guitars directly, without the
need for a DI box.
• The 3-band EQ has shelving high, shelving
low, and peaking mid EQ with adjustable mid
frequency.

Stereo Channels 9/10 and 11/12
• Channels 9/10 and 11/12 are stereo channels,
and their controls affect signals coming into the
stereo line-level inputs
• The stereo channel EQ is a 4-band design with
shelving high, shelving low, and peaking lo-mid
and peaking hi-mid.
“U” like Unity gain
Mackie mixers have a “U” symbol on almost every level
control. It stands for “unity gain,” meaning no change in
signal level. The labels on the controls are measured in
decibels (dB), so you’ll know what you’re doing level-
wise if you choose to change a control’s settings.
Signal Flow
The block diagram on page 33 shows the signal fl ow,
but here is a short description of the fl ow through the
channel strip section:
The input signals from the mic, or line inputs go
through a preamplifi er whose gain is set by the gain
control .
The signal then passes through the low-cut fi lter
(mono channels only) the compressor circuit (ch. 1 to 6
only), the insert jack (mono channels only), the chan-
nel EQ, channel fader, pan control, and then onto the
main mix.
The mon 1 [33] and mon 2 controls [34] tap the
signal off just before (pre) the channel fader.
The FX 1 [35] and FX 2 controls [36] tap the signal
off after (post) the channel fader.
