DOMINION™ CONTROLS IN DETAIL
Power Indicator LED
e indicator LED on the control panel shows the operational readiness of the
Dominion subwoofer. Note: Dominion subwoofers DO NOT have a Power Switch.
Instead, the Dominion will automatically power up its internal amplier when it
detects audio at any of its inputs and will power down the internal amplier if no signal
has been detected for approximately thirty (30) minutes. While dormant in this “Low
Power Standby” mode, the Dominion consumes only a tiny amount of power (<0.5
watt). Refer to the chart below for the LED’s function and meaning.
LED Color Mode Condition
Green On Audio signal detected
Red Low Power Standy
When rst connected to power or
30 minutes after loss of audio signal
In the unlikely event that the Auto Turn-On feature is not sensitive
enough for a particular system, use a Y-adaptor cable (one female to two
male RCA type connectors) to split the incoming signal into both RCA
inputs on the Dominion. is will increase the input level by 6dB. Please
be aware that if there is any signicant noise entering the subwoofer’s
input, it may not turn o as desired. If this happens, remove the Y-adaptor
cable and/or look for the noise source in upstream components.
e only way to completely power down a Dominion subwoofer is to unplug its
AC Power Cord. Do not use a switched outlet, power strip switch, or any other external
switch to interrupt or engage power to a Dominion, as this can result in undesirable
and potentially damaging transient pops.
LP Filter Switch
e “LP Filter” selector switch determines the operating mode of the built-in
active crossover of your Dominion.
“O defeats the crossover lter, completely removing this circuit from the
signal path and is most useful when using a receiver or preamp/processor’s lters
and bass-management features.
“On” activates the on-board active crossover. is crossover consists of a 24
dB/octave low-pass lter for signals feeding the internal amplier.
LP Frequency Knob
e “LP frequency (Hz)” selector knob allows the user to choose the crossover
frequency of the built-in active crossover of your Dominion. It has no eect
when the “LP Filter” switch is in the “o” position. e frequency is variable from
25 Hz (full counter-clockwise) to 130 Hz (full clockwise). 80 Hz is a commonly
used lter frequency and usually serves as a good starting point for adjustments.
