Selecting Dolby Surround - Aiwa AV-D78 Operating Instructions Manual

DOLBY SURROUND AND DTS SURROUND
This unit is equipped with the Dolby Pro Logic decoder, Dolby
Digital decoder and DTS decorder.
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, Dolby Digital
surround or DTS 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 Dolby surround sound or DTS surround
sound, adjust the speaker sound levels to the proper
balance (see page 17).
¢ Make sure the speakers are properly connected and positioned
(see pages 6 and 7).
¢ Make sure the TV set and video unit are properly connected
(see page 4).
¢ Make sure the disc and video tape, etc., support Dolby Pro
Logic, Dolby Digital surround or DTS surround.
SELECTING DOLBY SURROUND
