Channel Controls
The vertical channel strips look very similar, with only
a few differences between them. Each channel works
independently, and just controls the signals plugged into
the inputs directly above it. There are three different
flavors of channel strip: Mono, Hybrid and Stereo.
Mono Channels (1–4 on ProFX12)
(1–2 on ProFX8)
• The mono channel controls affect both the
mono mic input and the mono line-level input.
• The gain knob adjusts both mic and line inputs.
• Each mono channel has an insert jack and low
cut switch.
• Channel 1 has a hi-z switch to connect a guitar
directly.
• The 3-band EQ has shelving high, shelving low,
and peaking mid EQ.
Hybrid Channels (5/6, 7/8 on ProFX12)
(3/4, 5/6 on ProFX8)
• Except for gain and low cut, these controls
affect the mono mic input and the stereo
line-level input.
• The gain knob adjusts the mic input only. (The
stereo line inputs are fixed at unity gain.)
• The low cut switch only affects the mic input.
• The mono mic input is split equally to the left
and right.
• The hybrid channel EQ is a 3-band design just
like the mono channel EQ.
Stereo Channels (9/10, 11/12 on ProFX12)
(7/8 on ProFX8)
• These controls affect the stereo line-level
inputs.
• The gain knob adjusts the left and right line
inputs equally. There is no level set LED or low
cut switch.
• The stereo channel EQ is a 3-band design just
like the mono channel EQ.
“U” LIKE UNITY GAIN
Mackie mixers have a “U” symbol on almost every level
control. This “U” stands for “unity gain,” meaning no
change in signal level (0 dB gain). Once you have
adjusted the input signal with the gain control, set
every control at “U” and the signals will travel through
the mixer at optimal levels. What’s more, all the labels
on our level 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.
