Aiwa AV-D25 manual Selecting Dolby PRO Logic, To Select a Dolby PRO Logic Mode

This unit is equipped with the Dolby 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 14).

●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-R1 200 for surround speakers, the SX-C1 200 for a center speaker and the SX-AV1 200 for front speakers. Check your current type and placement of the speakers and select the recommended Dolby Pro Logic mode accordingly.

PHANTOM mode: Select this mode when the center speaker is not connected. All center channel signals are redistributed to the left and right channel speakers.
