FYI

From the liner notes on my Pro-Arte digital surround sound CD of
Tchaikovsky's 1812 Overture:

==============

Surround Sound

This digital Stereosurround recording has been created using
professional Shure HTS Stereosurround production equipment for
improved stereo-sound playback.  Fully compatible with all
conventional stereo-playback systems, the recording will provide an
enhanced listening experience unavailable from conventional stereo
recordings.

The 1977 sonic spectacular "Star Wars" debuted a new era of realism in
multichannel sound for movies.  For the first time, film-sound
presented the viewer with not only left-to-right stereo imaging that
had been enjoyed for decades in conventional stereo recordings, but
also information coming from the side and rear of the listener.  This
phenomenon creates an impressively lifelike sound-field.

Now a highly refined evolution of this remarkable technique is being
applied to digital music recordings by Pro-Arte.  Audiophile recording
techniques, used specifically for the production of state-of-the-art
compact discs with the most sophisticated Stereosurround system,
result in a crystal sound that creates a sense of "being there" like
no other listening experience today.

Listeners with conventional stereo-playback systems will enjoy
improved stereo imaging and a better sense of spatial depth.  These
added benefits of the Stereosurround process are most apparent when
the listener is facing as point in space between the stereo pair of
loudspeakers.

Listeners with Stereosurround playback systems, including Shure
AcraVector Logic or Dolby Surround Pro-Logic, will hear the
sound-field space presented more accurately with only two speakers
regardless of seating position.  Unlike some home-sound effects
processors, which give everything a particular sound until the user
changes modes again, the Stereosurround "encoding" tells your surround
decoder how to duplicate each and every sound as created and heard by
the artists and producers.  Any given Stereosurround recording will
put you in the best seat at that concert.  if different venues were
recorded on back-to-back cuts, your decoder would reproduce each one
for you.  Thus, the producer may take you to a majestic concert hall
for one recording and an intimate club for the next.  And because the
recording supplies the digital-signal processing program to tell your
surround decoder how to reproduce the sound, each new recording has
the potential to elevate you to new exciting experiences in music.
Please refer to instructions with you surround decoder for the proper
speaker placement.
