Dolby Pro Logic Surround, Dolby 3Ch Logic Center Mode; Speaker Installation A Vuceacsvssveesdennesadeiaiccerns; De Cngneiepraguehantieaey - Pioneer VSX-D601 Operating Instructions Manual

You can choose from the following settings:
Center Mode Choices:
When using a center speaker:
*® NORMAL -- Low range frequencies, which have little effect on
directionality and positioning, are routed to the left and right front
speakers. So you can use a relatively small size speaker as the center
speaker,
* WIDE — if you use a large size center speaker, choose this setting.
The full frequency range of the Dolby Surround center channel, from
low to high, is routed to the center speaker.
DOLBY PRO LOGIC SURROUND, DOLBY 3CH LOGIC CENTER MODE
When not using a center speaker: DOLBY PRO LOGIC SURROUND
® PHANTOM -- The signal which would have been sent to the center
speaker is divided equally between the left and right front speakers.
With DOLBY PRO LOGIC SURROUND, monaural source sound will be
heard only from the center channel at settings other than the PHANTOM
position.

If the rear speakers are positioned at an extreme distance, the surround
level becomes unable to adjust and the surround effect will not be fully
achieved.
NOTE:
* To avoid interference with the picture on a nearby TV set, use
magnetically shielded speaker systems. This is particularly important
for the center speaker since it is usually located closest to the TV.
* Position the left and right channel speakers at equal distances from
the TV set and approximately six feet from each other.
*® Position the center speaker above, below, ar behind the TV set. Sound
may not appear to coincide with the picture if you position it next to
the TV set.
* Rear speakers are best positioned stightly above ear level.
