Alignment
Dolby Digital Surround EX is defined as Format 13. The User 1 (U1) front panel
format button was assigned to this format at the factory, and is active when the
Cat. No. 794 is installed. If the U1 button was subsequently assigned to a different
format, reassign the U1 button (or U2 button) to Format 13.
The CP650 front-panel bar graph display and the PC setup software will now show
the additional surround outputs (Bsl and Bsr):
L C R Ls Rs SW Bsl Bsr L C R Ls Rs SW Bsl Bsr
(Bsl level=Bsr level) (Bsl level=Ls level), (Bsr level=Rs level)
The alignment procedure for the new surround outputs follows the same steps used
for the original Left Surround and Right Surround channels during the initial cinema
setup. Using the CP650 Installation Manual, follow the procedure for microphone
placement, RTA hookup, and SPL calibration; then perform level calibration and
equalization for all speaker channels:
Initial Output Level Calibration—Select and set each main output channel
(C, L, and R) to 85 dB, and set each surround output (Ls, Bsl, Bsr, Rs) to 82 dB.
Coarse (Bulk) Equalization—Adjust the EQ on all speakers.
Fine (1/3 octave) Equalization—Adjust the EQ on all speakers.
Final Output Level Calibration—Select and set each main output channel to
85 dB, and each surround output to 82 dB.
