Normally stereo reproduction uses left and right speakers, but
Dolby Pro Logic Surround
also uses a centre channel and a rear
channel. The centre channel sharpens sound perspective and dialogue clarity whilst the rear channel is used to immerse the viewer
in ambience and special effects.
To use
Dolby Pro Logic Surround
when receiving television programmes that have been encoded with
Dolby Surround
information, you must be able to receive NICAM Stereo transmissions. If NICAM Stereo transmissions are not transmitted in your
area then the
Dolby Surround
information will not be present and Pro Logic decoding will produce a centre channel only output
(unless you are playing back from a stereo VCR, Digital Versatile Disc etc.).
Dolby Pro Logic Surround
operates best with videos, laserdiscs and TV programmes that bear the
Dolby Surround
logo, but can
also be used to good effect with stereo sources not encoded in Dolby Surround and mono sources, affording compatibility with any
source.

Normal, Phantom or 3 Stereo modes,
as described on page 33.
Choosing Simulated allows selection of

described on page 34.
Allows adjustment of the output levels for each channel, as described on page 34.
Allows setting of the distance from the listening position to the front speakers.
Allows setting of the distance from the listening position to the rear speakers. If the rear surround speakers
are closer to you than the centre speaker, you may hear dialogue “leakage” from the rear surround
speakers. It may be necessary to reduce the output level of the rear channel to rectify this phenomenon.
Normally set to
On
, but, when separate external amplified front speakers are connected, then the internal
speakers can be switched
Off
. See page 41 for connection details.
