❸
CONTOUR
: This control provides access to two different overall
system responses:
Music
or
Film
. Selecting
Music
does not alter
the subwoofer's response. Selecting
Film
provides a tailored
boost at the lowest frequencies that many find desirable for film
sound reproduction. The response contour can be selected
either manually by changing the switch position to
Music
or
Film
, or automatically by selecting
External Trigger
to accept a
trigger voltage from an external device, such as a multi-channel
controller, applied to the
TRIGGER Music/Film
input terminals.
❹
LOW PASS/HIGH PASS
: The
LOW PASS
filter has
In/Out
and
24/48 dB
slope switches, and variable controls for
Frequency
,
Phase
, and
Level
. The
HIGH PASS
filter is always on and has a
variable
Frequency
control and
12/24 dB
slope switch. Use the
filter controls to precisely set a two-way crossover point from 30
to 80 Hz, with symmetrical 24 dB slopes or asymmetrical 24/12
or 48/12 dB slopes, and low-pass phase shift from 0 to 180
degrees. Use the
LOW PASS Level
control to set the subwoofer
system’s output level. When using a multi-channel controller,
the
LOW PASS Level
control is normally set to the “0” position.
❺
INPUT
: Use stereo XLR (balanced) connectors or RCA (unbal-
anced) jacks to connect from preamplifier outputs, or front
outputs of a multi-channel decoder. Both inputs are 0 dBv
(nominal)/+20 dBv (maximum). The XLR input is pin 2 high.
❻
AUX OUTPUT
: Use stereo XLR (balanced) connectors or RCA
(unbalanced) jacks to loop input audio signals to additional
REVEL ULTIMA SUB 30 subwoofers (if present). Both out-
puts are 0 dBv (nominal)/+20 dBv (maximum). The XLR out-
put is pin 2 high.
❼
HIGH PASS OUTPUT
: Use stereo XLR (balanced) connectors or
RCA (unbalanced) jacks for (high-pass) connection to the main
amplifier’s left input. Both outputs are 0 dBv (nominal)/
+20 dBv (maximum). The XLR output is pin 2 high.
❽
POWER ON MODE
: Select
Auto
to turn on automatic power
when the
POWER
switch is set to
ON
. Internal sense circuits will
continually detect the presence of audio signals and fully turn
on the power supply when needed. After some time, when
audio is no longer present, the same circuits will instruct the
power supply to enter the standby mode to conserve energy.
Or select
12V Trigger
to turn on/off power via a remote 12 Vdc
supply. A 12-volt trigger voltage is available from some multi-
channel audio/video controllers, as well as from integrated
remote control systems.
