amplifiers is switched off.) If repeated attempts at
AutoSetup
fail, you can set the speaker lev-
els manually using the noise sequencer or static noise generator modes. (See Chapter V:
“Manual Setup”).
Following successful completion of AutoSetup , adjust the subwoofer level through the pro-
cedure described below. (This step is not necessary in setups with no LFE subwoofer.)
Notes:
1. The
AutoSetup
procedure can be aborted at any time by pressing
➞
o
on the remote control.
2. If no microphone is plugged in, AutoSetup will automatically abort.
3. To use
AutoSetup ,
all five speakers (LF, CTR, RF, LS, RS) must be present. For systems with fewer
speakers, please see Chapter V: “Manual Setup”.
4. Occasionally one can obtain a speaker phase result that is surprising. For example, identical speakers
(e.g., those used for the front left and right stereo speakers) wired to different channels of the same power
amplifier should yield the same phase. If they do not, first carefully check the wiring (with a
continuity tester, if necessary) to verify that correct polaroty has been observed.
5. If everything appears normal and the phases
still
appear to be wrong, then it is possible that
AutoPhase is mistaken—which is rare but could conceivably happen under circumstances of unusual
or strong room reflections. In such cases, go with what you know is right. Once in a blue moon, a
driver inside a speaker box may be wired with reverse polarity, so keep this in mind.
6. You can experiement with
AutoPhase
by moving the microphone to a different region of the room
and repeating AutoSetup. Always finish up by repeating AutoSetup with the microphone in the sweet
spot to ensure correct speaker distances.
B. Setting the subwoofer level:
The only really reliable way of setting the main subwoofer volume level is to adjust it to your
personal preference while listening to program material. (The pink noise generator used by
AutoSetup cannot be used to accurately set the subwoofer level.) If the front stereo speakers
(LF and RF) are being crossed over to the LFE subwoofer, 2-channel stereophonic music
will generally afford the most suitable program material for accurately setting the subwoofer
volume. Otherwise, you will need to adjust the subwoofer volume during multi-channel
playback, such as Dolby Digital or DTS 5.1-channel program material.
Enter the Speaker Adjustment Screen (see figure, page 16) by pressing
Adjust
on page 2 of
the remote control’s
Setup 1
device. While in this screen, select the subwoofer for adjust-
ment by pressing the
SUB
button on the remote control. The subwoofer designator letters
“SB” will highlight on the TheaterMaster’s display. Adjust the subwoofer volume by pressing
VOL+
or
VOL-
on the remote control.
For ideal system balance, it is important that the subwoofer volume level displayed on the Speaker
Adjustment Screen be roughly similar (within about 10 dB) to the center speaker level (marked “CR”).
If the “SB” level is grossly different from the “CR” level, this could indicate that the volume control
on the active subwoofer (if you have an active subwoofer) is set too high or too low. If this is the case,
use the TheaterMaster subwoofer adjustment procedure described above to raise or lower the subwoofer
“SB” level to be approximately equal to the “CR” level. Then, adjust the subwoofer volume control on
your active subwoofer so that the subwoofer volume is approximately balanced with the rest of your
speakers. Then, the TheaterMaster subwoofer adjustment procedure described above can be used to
fine tune the subwoofer adjustment.
