MQ 302

STEREO GRAPHIC EQUALIZER

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 

OUTPUT

S simultanesously if desired.
