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 DOLSY 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-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.

The recommended mode

	Center speaker
	Larger-size	Smaller-size	No speaker
Surround speaker (Rear speaker)	DOLBY PRO LOGIC-WIDE	DOLBY PRO LOGIC-NORMAL	PHANTOM
No surround speaker	3CH LOGIC-WIDE	3CH LOGIC-NORMAL	-
