DOMINION™ CONTROLS IN DETAIL
Power Indicator LED
The 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 amplifier when it
detects audio at any of its inputs and will power down the internal amplifier 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.

Red Low Power Standy
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™. This will increase the input level by 6dB. Please
be aware that if there is any significant noise entering the subwoofer's
input, it may not turn off as desired. If this happens, remove the Y-adaptor
cable and/or look for the noise source in upstream components.
The 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
The "LP Filter" selector switch determines the operating mode of the built-in
active crossover of your Dominion™.
"Off" defeats the crossover filter, completely removing this circuit from the
signal path and is most useful when using a receiver or preamp/processor's filters
and bass-management features.
"On" activates the on-board active crossover. This crossover consists of a 24
dB/octave low-pass filter for signals feeding the internal amplifier.
LP Frequency Knob
The "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 effect
when the "LP Filter" switch is in the "off" position. The frequency is variable from
25 Hz (full counter-clockwise) to 130 Hz (full clockwise). 80 Hz is a commonly
used filter frequency and usually serves as a good starting point for adjustments.
