Record the serial number in the space provided below. Refer to them whenever you call upon your Sony dealer regarding this product. ___________________________________________ ___________ Serial No. [. . . ] · NO If you have not connected a surround back speaker, select "NO". · SINGLE If you connect only one surround back speaker, select "SINGLE". The sound will be output to a maximum of 6. 1 channel. · DUAL If you connect two surround back speakers, select "DUAL". The sound will be output to a maximum of 7. 1 channel. Tip The "LARGE" and "SMALL" settings for each speaker determine whether 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 equalizer to boost the bass levels. For details, see page 38.
