e. Surround Equalization Alignment (Cat. No. 441)
Turn the freq control so that the notch is located over the peak noted in the previous step.
The treble and mid equalizer controls interact. Repeat the adjustments until no further
adjustment is required and you have attained the optimum frequency response.
Adjust the treble control on the Cat. No. 441 card for the best approximation to the desired
response shown.
Adjust the Cut and Q controls for the flattest response in this part of the spectrum.
