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 IN-
PUT 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.
2
EQ BYPASS switch
When pressed to BYPASS, the filter sliders have no effect. Since actual unity gain depends on varying slider settings, use the BY-
PASS switch to determine the unity gain position of the INPUT LEVEL control by comparing ACTIVE and BYPASS volumes.
3
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 guaran-
teed flat response. These are all at ⅓-octave intervals at official ISO center frequencies.
4
POWER switch and LED
Your basic, straightforward power switch. When the yellow LED is lit, the SEQ 30 is ready to go.
