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 E-Sub subwoofer system, we recommend that
you set your receiver or preamp/processor as follows (please turn off all E-Subs in
the system via their front panel power switches prior to making these adjustments):
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 E-Sub(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 E-Subs
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 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 E-Sub
subwoofer system (please turn off all E-Subs 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.
