Warning! To preserve HDCD playback compatibility, roll-off of the LF and RF speakers is automat-
ically disabled in Stereo and Matrix playback modes. (Roll-off of these speakers would modify the
data streams seen by the HDCD digital filters, and would thereby prevent proper HDCD decoding.)
Therefore, as stated previously, it is essential that the LF and RF speakers be capable of accepting
without damage, if not actually reproducing, full bandwidth bass information. If such full-range
speakers are not available, then the
HDCD override DIP switch (DIP switch #5) on the mother-
board can be turned ON (switched to the back direction). This must be performed while the The-
aterMaster is disconnected from AC power , using a flashlight and a long, narrow screwdriver,
inserted through the left top-cover cooling vents. Switching this switch will allow roll-off of
the LF and RF speakers in all listening modes, including Stereo and Matrix, and thereby protect the
LF and RF speakers from bass information. However, rolling off the LF and RF speakers using this
HDCD override switch precludes HDCD playback. (See Chapter VII: “E. HDCD”.)
Choosing speakers to be crossed over:
Speakers selected for roll-off are automatically crossed over to the subwoofer (or to the LF
and RF speakers, for systems with no LFE subwoofer—see page 13). This is indicated by an
“
x
” (for “x-over”) next to the speaker on the Bass Management Screen.
However, as explained above, you may also wish to cross over additional speakers to the sub-
woofer—speakers that do not
need
to be rolled off, but whose bass response could nonetheless
benefit from augmentation by a subwoofer. This is accomplished by the following:
Access the Bass Management Screen by pressing
Bass X-Over
(or
Bass RolOff
) on page 3 of
the remote control’s
Setup 1
device. Choose speakers to be crossed over by pressing
Bass X-over - LF (or RF ), CR , or LS (or RS ). Removal of bass cross overs is accomplished
by pressing Bass X-Over - LF (or RF ), CR , or LS (or RS ) again. Exit this screen by pushing
the
➞
o
button.
Note: You cannot de-select a speaker to be crossed over that has been rolled off. Doing so would lead to
the loss of important bass information for that channel. You also cannot roll off or cross over the LF
and RF speakers when the subwoofer is disabled—see page 13).
Choosing a cross-over frequency:
Choosing a crossover frequency is accomplished by pressing
SUB

control’s

device. This will bring up the TheaterMaster’s System Configuration
Screen (see figure, page 18). While in this screen, the cross-over frequency, shown as
