PREPARATION FOR SETUP PROCESS:
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 Fathom IWSv2 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 to the Fathom IWSv2(s).
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 Fathom
IWSv2s 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 "0" or its
middle position.
4. Tone Controls / Equalizers
Set all tone controls 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 Fathom
IWSv2 subwoofer system (please turn off all Fathom IWSv2s in the system prior
to making these adjustments):
1. Low-Pass Filter Frequency
Select a low-pass filter frequency of 80 Hz (12dB/octave slope)
2. High-Pass Filter Frequency
Select a high-pass filter frequency of 80 Hz (12dB/octave slope)
3. Low-Pass (Subwoofer) Output Level
Set the subwoofer output level to "0" or its middle position.
