B-Chain Alignment Procedures

a. Setting Room Equalization

Notes

Change the NORMAL/BYPASS switch to the BYPASS position. Remove the center channel Cat. No. 64 equalizer module and plug the Cat. No. 67 extender in its slot. Then plug the equalizer module into the free end of the extender.

Restore the switch to the NORMAL position and make certain the format switch is still in the 04 position.

Turn on the center channel only on the Cat. No. 85C.

While observing the RTA display, adjust the bass control on the Cat. No. 64 so the bass frequency response is approximately flat. Once you set this control, do not change the setting during the rest of the room equalization procedure.
