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.
Cable Wiring
In agreement with IEC and AES/ANSI standards, XLR wiring convention is pin 2 Positive
(hot), pin 3 Negative (cold), and pin 1 Signal ground (for unbalanced use). Pin 1 and the
connector case or shell are tied to chassis ground.
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.
