Input Toggle Switches - select which source will be live to that channel based on what you have connected to the rear panel input section. Mic Gain­ controls the mic volume for the 1/4" connector on the rear of the mixer. Treble and Bass ­ for fine-tuning the tone of your voice on both mics through the sound system. Replaceable Crossfader - achieves clean segues between channels 2 and 3. 9 14 12 13 6. EQUALIZER 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. Faders have a center detent for an accurate "flat" response. This is a typical "house" EQ curve. 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 612dB. 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. Use the crossfader for fast and seamless segues from one selected channel to the other. 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" . · As a general rule, less equalization is better! - The Leader in DJ Technology ©1999 Industries -6http://www. numark. com DM1090X OUTPUTS 7. Stereo/Mono toggle - adjusts the Master output for stereo or mono operation. Volume Meter- quickly and accurately tracks dB level of audio sent to it from the master fader. It's OK to "tap the red" as long as the red LEDs aren't constantly lit. Proper attention to the meter results in the punchiest possible sound without audible distortion. Channel Cue/Send Assign - are used to route PFL channel audio to the Monitor Section.
