Sony STR-DE245 21GB, Adjustable parameters for each sound field when selecting programme source

Using Surround Sound

Adjusting the delay time (PRO LOGIC sound field only)

You can make the surround sound more effective by delaying the output from the rear speakers (delay time). You can select from three delay times, S (15 mS), M (20 mS), and L (30 mS). For example, if you’ve placed the rear speakers in a large room or apart from your listening position, set the delay time shorter.

2Press SUR.

The current delay time appears in the display.

3Press +/– to select the level you prefer, such as “DELAY S”, “DELAY M” or “DELAY L”.
