Quick recap: In the up position, the Tape Monitor switch selects the main Left and Right bus outputs for the monitor circuits and the meters. In the down position, the Tape Monitor switch selects the Tape Inputs for the monitor circuits and the meters.

MICROPHONE PREAMPLIFIERS

Another Mackie bonus feature! How did this come about? Was there just too much blank space on the back panel? Did somebody say, “Well, what if you have a microphone?” We’ll never know. But the happy fact is, in addition to all the fabulous stereo line input features you could possibly want, there are two high-performance Mackie microphone preamplifiers hidden away on the rear panel, just in case you need them.

The mic preamps each have a standard XLR-3 input connector, a trim control, and switchable phantom powering. However, they don’t go anywhere (non-normalled). That’s up to you.

To use a mic preamp, simply patch one of the (unbalanced 1⁄4") Mic Out jacks into any one of the line input jacks of the mixer. Patch ’em in mono, patch ’em in stereo, patch ’em anywhere your cord will reach.

NOTE: While dynamic

mics ignore phantom

power, ribbon mics don’t.

Make sure that the Phantom Power switch is off

before plugging in a ribbon mic. Wouldn’t want to barbecue your Beyer®…

The Long Arm Exercise revisited

The mic Trim knob will add from +10dB to +50dB of sensitivity to an LM-3204 input. For proper level setting, put all the controls in your signal path at the “U” detent and solo the input module you are using for a mic input. Then, while someone is making appropriate noises in front of the micro- phone, adjust the mic trim so that the peak levels read about 0dB on the meters.

If you are using condenser microphones, don’t forget to engage the Phantom Power switch, located between the two mic trim knobs.
