CONNECTIONS:
1.
Set all satellites to 'large' and subwoofer to 'yes' in your player's speaker setup menu.
2.
Run a cable from the
player's
analog SW output to subwoofer #1. This is the LFE
subwoofer, so if you have 2 different kinds of subwoofers and one of them is a bottom
feeder, use it.
NOTE:
If your player doesn't have enough signal output, you may have to insert a preamp between the
player and the subwoofer. You have the following 3 options: 1) use any channel of an old stereo
preamp or receiver that's not being used, 2) use an old stereo preamp that you're not currently using,
or, 3) purchase a mono preamp by Behringer, A.R.T., etc., on-the-cheap.
3.
Connect the remaining 5 cables from the player to the Pre/Pro or Receiver analog inputs
(no subwoofer input). If the Pre/Pro or Receiver doesn't have on board analog bass
management, connect the 5 cables to the ICBM inputs and then into the Pre/Pro or
Receiver, while making sure that FL, C, FR, SL and SR are followed through the chain.
4.
Connect a cable from the SW (subwoofer) output of the Pre/Pro or Receiver or ICBM
(whichever the case is in your setup) to subwoofer #2. This is the redirected bass
subwoofer.
THIS IS WHAT HAPPENS:
1.
The player outputs only the LFE signal to the LFE subwoofer. Most players have a global
120 Hz low pass filter on their analog SW output (check your manual). If not, you can use
the filter that's built into your powered subwoofer's plate amplifier. You can set the filter
to any point that sounds best to you, as this filter is unrelated to the rest of your bass
management in the system.
2.
The Pre/Pro or Receiver or ICBM SW output will now only output the redirected bass from
the satellites because there is no LFE signal input into it in the first place (remember you
headed that signal off at the player and ran it directly to subwoofer #1).
3.
You will now be able to tweak subwoofer #2 to achieve the best blend with your satellites,
in your room.
4.
You can select any crossover point that may be available in your setup's analog bass
management configuration and not affect the LFE signal at all.
5.
Placement, phase and level adjustments are the same as for the setup procedures
outlined above, with 1 exception: The LFE subwoofer's level must be set by using the
player's subwoofer calibration tone.
6.
It should also be set to 73 dB (if 75 dB is the reference level used for the satellites).
7.
Also, you should switch cables with the redirected bass subwoofer when running a
frequency sweep and charting response onto a graph because a test tone CD won't have
an LFE signal and, therefore, won't output the tones to the LFE subwoofer.
