Dolby Surround; Selecting Dolby Surround - Aiwa AV-D67 Operating Instructions Manual

DOLBY SURROUND

This unit is equipped with not only the Dolby Pro Logic decoder
but also the Dolby Digital decoder.
The unit and the center and surround speakers (standard) assure
full-scale home theater sound. When playing back discs or video
software that have been recorded in Dolby Pro Logic or Dolby
Digital Surround, astonishingly realistic sound surrounds the
listener to create a new level of audio/visual entertainment.
Independent control of the five channels allows the listener to
enjoy the same type of sound reproduction experienced in movie
theaters. Voices are reproduced in the front and center sound
field, while ambient sounds like cars and crowds are reproduced
on all sides of the listener for an incredibly lifelike audio/video
experience. Please read the following carefully to "tune" the
system's output to match the characteristics of your listening
space.
Check the following:
• Before enjoying the DOLBY SURROUND sound, adjust the
speaker sound levels to the proper balance (see page 16).
• Make sure the speakers are properly connected and positioned
(see pages 4 and 5).
• Make sure the TV set and video unit are properly connected
(see page 3).
• Make sure the disc and video tape, etc., support Dolby Pro
Logic or Dolby Digital Surround.

SELECTING DOLBY SURROUND

The optimal Dolby Digital Surround and Dolby Pro Logic modes
and settings depend on the type and placement of the speakers.
It is recommended that the optional Aiwa speakers should be
used for all channels, for example, the SX-AVR2900 speaker
system.
Check the current type and placement of your speakers and
select the recommended mode accordingly.
