The display shows “Invalid Reference” if the CP650 room
equalization settings were changed after reference measurements
were stored. A new set of reference measurements must be
stored.
Auditorium Assist automatically begins the
measurement sequence, beginning with an
auditorium noise floor measurement, then cycling
through all channels. The channel being measured
is displayed.
Note:
The CP650 outputs pink noise at 85dBC for the L, C, and
R channels; 82dBC for each of the surround channels; and
+10dBr for the subwoofer.
Upon completion, channels are listed with “OK”
for pass, or “X” for fail. Any “X” (failure)
indication is logged into the event log.
(See Section 9.3.3.)
