B-Chain Alignment Procedures

e.Surround Equalization Alignment (Cat. No. 441) Notes

Open the CP65 and place the NORMAL/BYPASS switch in the BYPASS position.

Remove the Cat. No. 85C card and re-install the Cat. No. 150 card.

Restore the BYPASS/NORMAL switch to the NORMAL position.

Confirm that format 04 Dolby Stereo A-Typeis selected.

Thread and play the Cat. No. 151 stereo optical surround level film. Check the sound by walking around the theatre. The surround and center channels should sound equally loud at most locations and left and right surround channels should sound equally loud and have similar frequency response in the center of the theatre. If necessary, readjust the left and right surround gains until you are satisfied with the surround-to-front center balance. A large change in the gain setting should be unnecessary.
