MICROPHONE CONNECTIONS

Here’s a Mackie bonus: two mic preamps hidden away on the back panel!

The Mic In connectors are standard female 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 adjusted by two Trim controls.

You can patch the mic out signal into any channel input or even into other pieces of line level equipment in your rack.

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 1⁄4" 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.
