Important Note: In order for the CSE 6.1 to have appropriate information to properly decode
the rear center surround channel, the left and right surround channels must be set within 3
dB of each other when adjusted on your host 5.1 processor is calibrated. Be sure to check the
surround levels are matched closely enough before installing the CSE 6.1.
When No Calibration Is Required
When the CSE 6.1 is designed so that when the CS level control is in its middle “12 o’clock”
position, the Rear Center Surround Out sound pressure level should be nearly the same as
your left and right surround speakers and no calibration should be necessary. Thus, if your
CS speaker(s) and amplifier channels are identical to your LS and RS speakers and amplifier
channels, the levels will be similar.
Of course, you can increase or decrease the rear center surround level with respect to the left
and right surround speakers to account for the relative speaker sensitivity and amplifier gain
differences, or to suit your tastes.
Calibrating Your New CS Channel by Ear
If you use different amplifiers and/or speakers for the center surround channel, you can use
the built-in test tone generator to insure that the center surround speaker level is the same as
the left and right surround speakers. You can also use the calibration circuit to confirm that
the middle CS level knob position is the proper setting for your home theater.
Calibration Procedures
1. Turn on your home theater system.
2. Take a seat in your customary listening/viewing location.
3. Set the CS level to minimum by pressing the < Level button on your CSE 6.1 remote
control for 3-4 seconds.
4. Press the Engage button on the CSE 6.1 remote control.
3. Press the Calibrate button on the CSE 6.1 remote control.
4. The LS, CS and RS speakers (only) will reproduce the pink noise test tone at the same
time. The rest of the speakers will be silent.
5. From your listening position, slowly adjust the CS level with the < Level button on your
CSE 6.1 remote control until the “hole” in the middle of the rear soundstage is filled, but
the CS speaker is not louder than the LS and RS speakers.
6. After calibration, press the Calibrate button again to turn the test tone off.
7. Note the level on the front panel so you can reset the CSE 6.1 to the calibrated level
should you want to experiment with the rear center surround channel level.
You can also perform these functions with the front panel controls, but you’ll need to return
to your listening/viewing location to assess each adjustment. The front panel Engage button
reverts to Bypass when it is pressed a second time, whereas the remote control has a separate
Bypass button so you’ll know that the CSE 6.1 is in the bypass mode without having to view
its front panel indicator.
