N'° About speaker sizes (LARGE and SMALL)
Internally, the LARGE and SMALL settings fbr each speaker
determine whether or not the internal sotmd processor will cut
the hass signal fl'om that channel. Wben the hass is cut fi'om a
channel, the hass redirection circuitry sends the corresponding
bass fi equencies to the sub woofer or other 'LARGE" speakers.
Howeven since bass sounds have a certain amount of
directionality, it best not to cut them, if"possihle. Therefore, even
when using small speakers, you can set them to "LARGE" if you
want to output the hass frequencies fi'om that speaker. On the
other band, if you are using a large speaker, but prefer not to
have bass fi eqnencies output fi'om 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
equalizer to boost the bass levels. To adjust the eclnalizei; see
page 39.
