PREPARATION FOR SETUP:
Please confirm the following system settings before beginning the setup
process. This will ensure a neutral starting point and an effective setup of your
subwoofer system.
On your Home Theater Receiver or Preamp/Processor:
Before beginning setup of your Dominion™ subwoofer system, we recommend
that you set your receiver or preamp/processor as follows:
1. Speaker Size
In the speaker setup menu of your receiver or preamp/processor, set up all
of your high-frequency speakers as "small" with a crossover point of 80 Hz.
This will send ALL bass, from all channels, to the subwoofers and is the
recommended method for best performance, regardless of the actual size of
your main speakers (big or small).
2. Speaker Distance
In the speaker setup menu, properly set all speaker distances to the primary
listening seat, including the subwoofer's distance. Use a tape measure
to determine these distances (time coherence is important.) If multiple
Dominion™ subwoofers are being used, average their distances to the primary
listening seat and use that number to set the subwoofer distance.
3. Subwoofer Level
Set the "subwoofer level" in the receiver or preamp/processor to "0" or its
middle position.
4. Tone Controls / Equalizers
Set all tone controls (bass, treble, etc.) to "0" and defeat all equalizer features.
On your Active Crossover or Bass Management Processor:
If you are using an active crossover or bass-management processor, we
recommend that you set it as follows before beginning setup of your Dominion™
subwoofer system (please turn off all Dominion™ subwoofers in the system prior
to making these adjustments):
1. Crossover Filter Frequency
Select a low-pass filter frequency of 80 Hz (24dB/octave slope, if given an option)
2. Subwoofer Output Level
Set the subwoofer output level to "0" or its middle position.
