(V. Manual Setup)
This Chapter describes manual setup of the speakers and speaker delays, for customers who lack a
setup microphone or who are having technical difficulties with the
AutoSetup
™
procedure. This
Chapter can be skipped by readers who have successfully accomplished
AutoSetup .
A. Manual setup using the Noise Sequencer:
Press the
Noise Sequencer
key on page 1 of the remote’s
Setup 1
device. TheaterMaster’s
internal noise sequencer will begin cycling pink noise through the six speakers. You should
hear this noise. (If no noise is heard out of one or more speakers, check the speaker connec-
tions to those speakers and verify that the power amps are switched on.)
If no setup microphone is plugged into TheaterMaster’s rear-panel MIC jack, the Speaker
Adjustment Screen will be displayed. As the noise sequencer rotates among the various
speakers, the corresponding speaker will highlight.
Adjust the volume on the active speaker by pressing
VOL+
or
VOL-
. The noise sequencer
will pause on a given speaker while adjustments are being made to that speaker.
Note that the LF and RF speakers can only be adjusted simultaneously, in order to preserve
left-right stereo balance. The same holds for the LS and RS surrounds. To alter these left-
right channel balances, see “B. Manual setup using the Static Noise Generator”, below.
For optimal system balance, all 5 speakers (LF, CTR, RF, LS, and RS) should be adjusted 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”.)
When the setup microphone is plugged in, activating the noise sequencer automatically
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 lis-
tening position, pointing upward. Background noise and conversation should be minimized
during speaker calibration.
When the desired speaker balance is achieved, exit 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”.
B. Manual setup using the Static Noise Generator:
You might find in your system that your LF and RF speakers do not have the same apparent
loudness. If they don’t, it could mean that your front speakers or power amplifiers have dif-
ferent gains/efficiencies, or that your room acoustics are asymmetrical. In this case, you may
wish to adjust your left-right channel balance. This can be accomplished using the “Static
Noise Generator”.
The Static Noise Generator provides a more flexible and, in some ways, more convenient
manual setup procedure. To activate the static noise generator, press the speaker icon
