QUICK START
If this is your first equalizer, please do yourself and your speakers a favor and read at least the first five pages. "An
ounce of prevention...," and all that.
The MQ 302 is a stereo equalizer, so adjusting any slider affects both Channels simultaneously. Begin by setting all
sliders to their center detent (0 dB), and the INPUT LEVEL to 8. Try to make more cuts than boosts. After equalizing, use
the EQ switch to compare equalized and non-equalized signal. While EQ is switched to ACTIVE (out), adjust the INPUT
LEVEL to the same level as when EQ is switched to BYPASS (in).
You may use either the XLR or ¼" connectors for Inputs or Outputs. Connect only one INPUT type per channel. The
XLR and ¼" TRS inputs do not sum. You may, however, use both types of OUTPUTS simultanesously if desired.

POWER switch and LED Your basic, straightforward power switch. When the yellow LED is lit, the MC 22 is ready to go. LEFT & RIGHT INPUTS Choose between the balanced XLR or the balanced/unbalanced ¼" TRS jacks, but LEFT & RIGHT OUTPUTS only use one. - Page 4 Acoustic compensation is controlled nicely with a device this creates noise and hum problems. The MQ 302 operates at such as the MQ 302. The best way to “see” what room unity gain around “8” on the INPUT LEVEL control when acoustics are doing to your sound is to use a real time sliders average to center (0 dB).

If a graphic equalizer’s adjacent bands, when moved together, produce a smooth response without a dip in the center, they are interpolat- ing between the fixed center frequencies. bandwidth remains constant for all boost/cut levels. Since Q and bandwidth are interrelated, the terms are fully interchangeable.
