The vertical channel strips look very similar, and have
a only few differences between them. Each
channel works independently, and just controls the
signals plugged into the inputs directly above it.
Here are a few features and differences:
Mono Channels 1-8
• These are mono channels, and their controls
affect either the mono mic input or the mono
line-level input.
• Channel 1 and 2 each have a hi-z switch, so you
can connect guitars directly without the need
for a DI box.
• 48 Volt Phantom Power can be selected for each
mic input.
• High pass filters affects both the mic and line
inputs.
• Gain control adjusts the mic level and line
level.
• The 4-band EQ has shelving high, shelving low,
and peaking hi-mid and peaking lo-mid with
adjustable mid frequency.
Stereo Channels 9-16
• The stereo channels each have two line-level
inputs.
• For mono sources, use the left input only, and
it will appear equally on both sides of the main
mix.
• Gain control adjusts the line level only.
• The 3-band EQ has shelving high, shelving low,
and peaking mid EQ.
• Channel 15 and 16 have a switch to select
FireWire inputs instead of the analog line
inputs.
"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.
