If
no
setup microphone is plugged into TheaterMaster’s rear-panel MIC jack, the Speaker
Adjustment Screen will be displayed. Press the
LF
,
CTR
,
RF
, or any other speaker key on
the remote control. This will direct pink noise to the selected speakers only. The selected
speakers will highlight. Adjust the volume on these speakers by pressing and holding
VOL+
or VOL- .
Caution: In this mode, you can adjust the LF and RF volumes independently, providing a means to
adjust left-right channel balance. To preserve left-right channel balance throughout this setup procedure,
activate both LF and RF speakers, and adjust their volumes simultaneously. If you wish to restore
left-right balance at any time, select both the LF and RF speakers in this static noise generator mode,
go to
page 3 on the TheaterMaster device and press
F -
x - x (wher x - x is a two-digit number signi-
fying the number of dB below full output, F - 0 - 0 , or 0 dB) to set both speakers to the same volume
level. Similar comments apply to LS and RS. Then go back to page 2 of the
Setup 1
device to continue.
Press the selected speaker again to de-select that speaker. Use this procedure to adjust
all five speakers (LF, CTR, RF, LS, and RS) to equal sound pressure levels, which can be
determined either by ear or by use of a sound pressure meter. (See, however, Chapter IV:
“C. Tweaking the system”.) The subwoofer volume must be handled separately—see Chap-
ter IV: “B. Setting the subwoofer level”.
When the setup microphone is plugged in, activating the Static Noise Generator automati-
cally brings up TheaterMaster’s Calibrated SPL Meter Screen. This screen can be used in
place of an SPL meter to achieve accurate speaker balance. Hold the microphone in the
center listening position, pointing upward. Background noise and conversation should be
minimized during speaker calibration.
Exit the Static Noise Generator by pressing

o
on the remote control.
After completing this procedure, perform the automatic speaker delay calibration described
below, and then adjust the subwoofer level following the procedure described in Chapter IV:
“B. Setting the subwoofer level”.
C. Manual speaker delay calibration:
For customers who lack a setup microphone or who are having technical difficulties with
AutoDelay
, time alignment of the speakers can be accomplished manually.
To achieve this, first measure the distances (in meters) from the center listening position to
the center speaker (CTR), front speakers (LF or RF), and surround speakers (LS or RS).
Following these measurements, bring up the Speaker Distances Screen by repeatedly pressing
DISP
▼
on page 4 of the remote’s
TheaterMaster
device (see figure, page 16).
Once in the Speaker Distances Screen, go to page 2 of the remote’s
Setup 1
device. Then
select a desired speaker by pressing the corresponding speaker buttons on the remote con-
trol. This speaker will highlight. [Note that the front speakers (LF and RF) and surround
speakers (LS and RS) can only be selected in pairs.] Now increase or decrease the speaker
distances displayed to match your measured distances by pressing
CH+ or CH- . To exit and
store these distances, press
