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 IWS 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 IWS(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 IWSs 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 IWS subwoofer system (please turn off all Fathom IWSs 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.
