Manual-1

QUICK START

This manual is for both the SEQ 30s and the SEQ 30L. The only difference is the length of the sliders. The units are electrically 

and functionally the same. This manual will refer to “SEQ 30” for either unit.

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 pre-

vention...,” and all that.

The SEQ 30 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 its center detent (0 dB). 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

 

(

BYPASS button out

), adjust the 

IN-

PUT 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 simultaneously if desired.
