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.
햳
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.
햴
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.
