Tip

� If you connect a large speaker that will effectively reproduce bass frequencies, select �LARGE�. Normally, select �LARGE�. However, if the front speakers are set to �SMALL�, you cannot set the center speaker to �LARGE�. � If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select �SMALL� to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to �LARGE�) or sub woofer.*1 � If you do not connect a center speaker, select �NO�. The sound of the center channel will be output from the front speakers.*2 x Surround speaker size (

Internally, the LARGE and SMALL settings for each 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, the bass redirection circuitry sends the corresponding bass frequencies to the sub woofer or other �LARGE� speakers. However, since bass sounds have a certain amount of directionality, it is best not to cut them, if possible. Therefore, even when using small speakers, you can set them to �LARGE� if you want to output the bass frequencies from that speaker. On the other hand, 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 +/� to boost the bass levels. To adjust the bass, see page 30.

� If you connect a sub woofer, select �YES�. � If you do not connect a sub woofer, select �NO�. This activates the bass redirection circuitry and outputs the LFE signals from other speakers. continued
