DOLBY PRO LOGIC
The Dolby Pro Logic feature and the center and surround
speakers (standard) assure full-scale home theater sound. When
playing back laser discs or video software that have been
recorded in Dolby Surround, astonishingly realistic sound
surrounds the listener to create a new level of audio/visual
entertainment.
Independent control of the four 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 using the DOLBY PRO LOGIC, adjust the proper
balance of the speaker sound levels (see page 13).
• Make sure the speakers are properly connected and positioned
(see pages 3 and 4).
• Make sure the TV set and video unit are properly connected
(see page 3).
•Make sure the laser disc and video tape, etc., support

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-R2000 for surround speakers, the SX-C2000 for a center
speaker and the SX-AV2000 for front speakers. Check your
current type and placement of the speakers and select the
recommended Dolby Pro Logic mode accordingly.
