MICROPHONE CONNECTIONS
Here’s a Mackie bonus: two mic preamps hid-
den away on the back panel!
The Mic In connectors
are standard fe-
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.
The mic sig-
nals won’t go
anywhere un-
less you patch
them. Each
preamp has a

Mic Out jack.
You can patch the mic out signal into any chan-
nel input or even into other pieces of line level
equipment in your rack.
EXPANDER IN
The Expander In jack is where you plug in your
optional LM-3204E expander. See Appendix B.
PHONES OUT
The Phones jack is located on the front panel
to the right of the meters and below the Phones
Level knob. The jack is a standard
1
⁄

" TRS stereo
headphone jack with the left channel on the tip,
the right channel on the ring, and the common
ground connection on the sleeve. Careful; it’s
loud. It is an IC, and it will not drive a speaker
and it will toast a power amp (if turned up).
WARNING: Turn down the
Phones level control before
you plug in the headphones.
Then inch the control up
until you feel groovy.
