layout shows locations of
controls, as well as audio
and power connectors.
REAR PANEL LAYOUT
1 EQ1~EQ3 Controls: Three parametric equalizers includes vari-
able controls for FREQ., BANDWIDTH, and LEVEL. Use
these controls to modify the frequency response at three points,
adjustable from 18 to 80Hz, across a bandwidth from 0.1 to
1.0 octaves, with level boost up to 6dB or cut down to -14.5dB.
2 Low-Pass/High-Pass Filters: The low-pass filter has an ON/OFF
and 24/48dB slope switches, and variable controls for frequency,
phase, and level. The high-pass filter is always on and has a vari-
able frequency control and 12/24dB slope switch. Use the
controls to precisely set a two-way crossover point from 30 to
80Hz, with symmetrical 24dB slopes or asymmetrical 24/12 or
48/12 dB slopes, and low-pass phase shift from 0 to 180 degrees.
3 INPUT: Use stereo XLR (balanced) connectors or RCA (unbal-
anced) jacks to connect from preamplifier outputs, or front out-
puts of a multi-channel decoder. Both inputs are 0dBv (nomi-
nal)/+20dBv (maximum). The XLR input is pin 2 high.
4 AUX OUTPUT: Use stereo XLR (balanced) connectors or RCA
(unbalanced) jacks to loop input audio signals to additional
REVEL PERFORMA B15as (if present). Both outputs are 0 dBv
(nominal)/+20 dBv (maximum). The XLR input is pin 2 high.
5 HIGH PASS OUTPUT: Use stereo XLR (balanced)
connectors or RCA (unbalanced) jacks for (high-pass) connection
to the main amplifier’s inputs. Both outputs are 0dBv
(nominal)/+20dBv (maximum). The XLR input is pin 2 high.
