MICROPHONE CONNECTIONS
Here's a Mackie bonus: two mic preamps hid-
den away on the back panel!
The Mic In connectors
male XLR3-type microphone connectors, wired
to a pair of classic Mackie balanced mic pream-
plifiers with more headroom than a Kenworth
cab and less noise than a mortuary at midnight.
Pin 2 is wired high, pin 3 is low and pin 1 is
grounded, per AES standards.
Phantom mic powering can be applied to
both inputs with a flick of the Phantom Power
switch . Mic preamp levels are individually ad-
justed by two Trim controls.
