Getting Started x CTR SP XXXXX (Center speaker size) • LARGE 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". • SMALL 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.a) • NO If you did not connect a center speaker, select "NO". The sound of the center channel will be output from the front speakers.b) x SURR SP XXXXX (Surround speakers size) • LARGE If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE". However, if the front speakers are set to "SMALL", you cannot set the surround speakers to "LARGE". • SMALL 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 surround channel bass frequencies from the sub woofer or other "LARGE" speakers. • NO If you did not connect surround speakers, select "NO".c) x SB SP XXXXXX (Surround back speakers selection) When the surround speakers are set to "NO", the surround back speakers are also automatically set to "NO" and the setting cannot be changed. • DUAL If you connect two surround back speakers, select "DUAL". The sound will be output to a maximum of 7.1 channels. • SINGLE If you connect only one surround back speaker, select "SINGLE". The sound will be output to a maximum of 6.1 channels. • NO If you did not connect surround back speaker, select "NO". Tips • a)-c) correspond to the following Dolby Pro Logic modes a) NORMAL b) PHANTOM c) 3 STEREO • 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 BASS parameter in the EQUALIZER menu to boost the bass levels. To adjust the bass, see page 38. continued 19GB
