Aiwa AV-D50 - Manual (Page 15)

This unit is equipped with the Doiby Pro Logic decoder and also
supports the Dolby Digital decoder with the 5.1 ch output
terminals.
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
proper balance of the speaker sound levels (see page 15).
• Make sure the speakers are properly connected and positioned
(see pages 3, 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 PRO LOGIC
The optimal Dolby Pro Logic mode depends 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-R2500 for surround speakers, the SX-C2500 for a center
speaker and the SX-AV2500 for front speakers. Check your
current type and placement of the speakers and select the
recommended Dolby Pro Logic mode accordingly.
