The vertical channel strips look very similar, and have only a few differences between them. Each

channel works independently, and just controls the signals plugged into the inputs directly above it.

Mono Channels 1 and 2

•These are mono channels, and their controls affect either the mono mic input or the mono line-level input.

•Each channel has a hi-z switch, so you can connect guitars directly without the need for a DI box.

•High pass filter affects both the mic and line inputs.

•Gain control adjusts the mic level and line level.

•The 3-band EQ has shelving high, shelving low, and peaking mid EQ with adjustable mid frequency.

Hybrid Channels 3/4

• These hybrid channels have a mono mic input

and stereo line-level inputs. The mono mic

signal is sent in equal amounts to the left and

right sides of the stereo channel.

• High pass filter affects the mic input only.

• Line inputs are switchable +4 dB /–10 dB.

Stereo Channels 5-8

•These stereo channels have two line-level inputs.

•Gain control adjusts the line level only.

•The 3-band EQ has shelving high, shelving low, and peaking mid EQ.

•Channel 7 and 8 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.
