"_" About speakersizes(LARGE and SMALL)
Internally, the LARGEand SMALL settings foreach speaker
determine whether or not the internal sound processor will cut
the bass signal from that channel. When the bass is cut from a
channel tbe bass redirection circuitry sends the corresponding
bass frequencies to the sub woofer or other "LARGE" speaker.
However, since bass sounds have a certain amount of
directionality it best not to cut them, if possible. Therefore, even
when using small speakers, you can set tbem to "LARGE" if you
want to output the bass frequencies from that speaker. On the
other band, if you are using a large speaker, but prefer not to
have bass frequencies output from that speaker, set it to
"SMALL".
If the overall sound level is lower than you prefer, set all speakers
to "LARGE". If there is not enough bass, you can use the bass/
treble to boost the bass levels. To adjust the bass/treble, see page
35.
• Rear speaker position (REAR PL.)*
Initial setting : BEHIND
This parameter lets you specify the location of your rear
speakers for proper implementation of the Digital Cinema
