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 Gotham v2 subwoofer system we recommend
that you set your receiver or preamp/processor as follows (please turn off all
Gotham v2s 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 Gotham v2(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 Gotham
v2s 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 Gotham v2
subwoofer system (please turn off all Gotham v2s in the system prior to making
these adjustments):
1. Low-Pass Filter Frequency
Select a low-pass filter frequency of 80 Hz (24 dB/octave slope)
2. High-Pass Filter Frequency
Select a high-pass filter frequency of 80 Hz (24 dB/octave slope)
3. Low-Pass (Subwoofer) Output Level
Set the subwoofer output level to "0" or its middle position.
