C About speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings for each speaker
determine \s'hether or not the internal sound processor will cut
the bass signal from that channel. \N'hen the bass is cut from a
channel the bass redirection circuitr\’ sends the corresponding
bass frequencies to the sub woofer or other "LARGE" speaker.
HoweN’er, since bass sounds have a certain amount of
directionalitv it best not to cut them, if possible. Therefore, e\ en
when using small speakers, you can set them to "LARGE" if vou
want to output the bass frequencies from that speaker. On the
other hand, if vou are using a large speaker, but prefer not to
have bass frequencies output from that speaker, set it to
"SMALL".
If the overall sound le\ el is lower than vou prefer set all speakers
to "LARGE". If there is not enough bass you can use the
equalizer to boost the bass levels. To adjust the equalizer, see
page 40.
