We've designed a lot of boost and cut into each equalizer circuit, because we know everyone will occasionally need that. But if you max the EQs on every channel, you'll get mix mush. Equalize subtly and use the left sides of the knobs (cut), as well as the right (boost). Very few gold-record-album engineers ever use more than about 3dB of EQ. If you need more than that, there's usually a better way to get it, such as placing a mic differently (or using a different kind of mic entirely). AUX SEND These tap a portion of each channel signal out to another source for parallel effects processing or stage monitoring. AUX send levels are controlled by the channel's AUX 1 and AUX 2 knobs and by the AUX 1 MASTER . These are more than just effects and monitor sends. They can be used to generate separate mixes for recording or "mix-minuses" for broadcast. By using AUX 1 in the PRE mode , these mix levels can be obtained independently of the channel's GAIN control. AUX 1 in POST-mode and AUX 2 are post-LOW CUT, post-EQ and post-FADER. That is, the sends obey the settings of these controls. AUX 1 in PRE mode follows the EQ and LOW CUT settings only. PAN and FADER have no effect on the PRE send (see diagram below). All AUX send levels range from off through unity (with their channel gain controls at the center detent position) on up to 15dB of extra gain (when turned fully clockwise). Chances are you'll never need this extra gain, but it's nice to know it's there if you do. Channel 7-14 AUX pots control the mono sum of the channel's stereo signals for each AUX send. For instance, Channel 7 (left) and 8 (right) mix together to feed that channel's AUX send knobs. We recommend going into a stereo reverb in mono and returning in stereo. We have found that most "stereo" reverbs' second input just ties up an extra AUX send and adds nothing to the sound. There are exceptions, so feel free to try it both ways. If your effects device is true stereo all the way through, use AUX 1 to feed its LEFT input and AUX 2 to feed the RIGHT input.
