SEQ 30S
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 SEQ 30S 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 (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 simultaneously if desired.
WEAR PARTS: This product contains no wear parts.
Manual-1
INPUT LEVEL control and indicators
This controls the overall level. 0 dB gain is reached at the center detent with all
sliders centered at their 0 dB detents. Set the INPUT LEVEL to give equal volumes
with the EQ switched to ACTIVE or BYPASS, after setting the sliders (see EQ
BYPASS switch below). Apply sufficient signal to the input to occasionally light
the +4 dBu indicator. Flashing of the OL (overload) LED during peaks can be
avoided by turning the INPUT LEVEL or boosted Filters down.
EQ BYPASS switch
When pressed to BYPASS, the filter
sliders have no effect. Since actual unity
gain depends on varying slider settings,
use the BYPASS switch to determine
the unity gain position of the INPUT
LEVEL control by comparing ACTIVE
and BYPASS volumes.
Filter level slide controls
Each of these sliders control the
output level of both channels of the 30
bandpass filters. Center position is
grounded for guaranteed flat response.
