The vertical channel strips look very similar, and have
AUX RETU
BAL/UNBAL only a few differences between them. Each
1
channel works independently, and just controls the
L
signals plugged into the inputs directly above it.
(MONO)
Here are a few features and differences:
R
Mono Channels 1 and 2
• These are mono channels, and their controls
L
affect either the mono mic input or the mono
(MONO)
BAL/UNBAL
line-level input.
R
• Each channel has a hi-z switch, so you can
connect guitars directly without the need for a
U
DI box.
GAIN
• High pass fi lter affects both the mic and line
20dB
+
inputs.
INPUT
• Gain control adjusts the mic level and line

level.
HIGH
12kHz
• The 3-band EQ has shelving high, shelving
15

low, and peaking mid EQ with adjustable mid
U
frequency.
MID
2.5kHz

Hybrid Channels 3/4
• These hybrid channels have a mono mic input
U
LOW
and stereo line-level inputs. The mono mic
80Hz
15

signal is sent in equal amounts to the left and
AUX
right sides of the stereo channel.
1
• High pass fi lter affects the mic input only.
MAX
• Line inputs are switchable +4 dB /–10 dB.
2
• Gain control adjusts the mic level only.

PAN
• The 4-band EQ has shelving high, shelving low,
with peaking lo-mid and peaking hi-mid.
R
Stereo Channels 5-8
• These stereo channels have two line-level
OL
- 20
inputs.
U
• Gain control adjusts the line level only.
• The 3-band EQ has shelving high, shelving low,
+10dB

and peaking mid EQ.
• Channel 7 and 8 have a switch to select
7-8
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.
