Multi-Channel Surround Setupz About speaker sizes (LARGE and SMALL)

	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” speaker.
	However, since bass sounds have a certain amount of
Hooking
	directionality it 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
Up	other hand, if you are using a large speaker, but prefer not to
	have bass frequencies output from that speaker, set it to
and
	“SMALL”.
Setting	If the overall sound level is lower than you prefer, set all speakers
	34.
	to “LARGE”. If there is not enough bass, you can use the
	equalizer to boost the bass levels. To set the equalizer, see page

zAbout the rear speaker position (SIDE, MIDDLE, and BEHIND)

This setting is designed specifically for implementation of the Digital Cinema Sound modes in the VIRTUAL 3D genre.

With the Digital Cinema Sound modes, speaker position is not as critical as other modes. All of the modes in the VIRTUAL 3D genre were designed under the premise that the rear speaker would be located behind the listening position, but presentation remains fairly consistent even with the rear speakers positioned at a rather wide angle. However, if the speakers are pointing toward the listener from the immediate left and right of the listening position, the VIRTUAL 3D modes will not be effective unless the rear speaker position parameter is set to “SIDE”. Nevertheless, each listening environment has many variables, like wall reflections, and you may obtain better results using “BEHIND” or “MIDDLE” if your speakers are located high above the listening position, even if they are to the immediate left and right.

Therefore, although it may result in a setting contrary to the “Rear speaker position” explanation, we recommend that you playback multi channel surround encoded software and listen to the effect each setting has on your listening environment. Choose the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the rear speakers and the sound of the front speakers. If you are not sure which sounds best, select “BEHIND” and then use the speaker distance parameter and speaker level adjustments to obtain proper balance.
