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 controls 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

This controls the overall level. +6 dB gain is

reached at “10” with all sliders centered at

0 dB (see BYPASS switch below).
