We have divided this section into various functional blocks: Inputs, Microphone, Crossfader, Equalizer, Outputs, and Headphone Cueing. It is important to learn how each of these work.

I N P U T S

1.Input faders - control individual source levels in the mix.

2.Input Toggle Switches - select which source will be live to that channel based on what you have connected to the rear panel input section.

MICROPHONE

3.Mic Gain– controls the mic volume for the 1/4” connector on the rear of the mixer.

4.Treble and Bass – for fine-tuning the tone of your voice on both mics through the sound system. The controls are detented for setting tone "flat". For best results, use a dynamic cardioid microphone.

EQUALIZER

6.5-Band Stereo Graphic Equalizer (EQ) - compensates for differences in source material sound quality. In ultra-compact mobile systems this EQ can be used to tailor the sound to the acoustical requirements of the room. Center frequencies are 63Hz, 250Hz, 1kHz, 4kHz and 16kHz. Faders have a center detent for an accurate "flat” response.

This is a typical "house" EQ curve. Notice how the knobs above "0" balance out the knobs below. Start with this setting if you've never used a graphic EQ before.

This is an example of a poor EQ curve because it cuts the output volume down by 6- 12dB. You have to compensate by running the M a s t e r output higher.

CROSSFADER

5.Replaceable Crossfader - achieves clean segues between channels 2 and 3.

Below is the worst sort of curve to use because you are using EQ to add volume. With exaggerated boost, you can easily run your power amplifiers into “clipping” and damage your speakers.

"Hard left" selects Channel 2 and "Hard right" selects Channel 3. With the crossfader centered, both channels are live. Use the crossfader for fast and seamless segues from one selected channel to the other.

Note: The crossfader is user replaceable in case of failure. Simply unscrew the two large screws that hold it in place, lift it out and disconnect its cable. Re-attach the new crossfader and screw the mounting plate back onto the unit - you’re back in business!

GENERAL EQ HINTS

•Boost the 63Hz band for deep bass tones and solid kick drum sound. Use sparingly because this dramatically increases demand on power amplifiers and could drive them into “clipping” .

•Cut slightly at 250Hz and more at 1kHz for extra clarity.

N o t e : Cutting is preferable to boosting.

•Boost 16kHz for a little "sizzle".
