P/SP-1500 Owner's Manual 13

Surround Channel Delay

The surround delay circuitry allows you to choose the amount of time it takes sound from the surround channel speakers to follow the sound from the front left, right, and center speakers. This establishes the precedence effect for the front channel speakers and helps you associate the sound with the image on the screen rather than from behind you. (The precedence effect is how our hearing tends to identify or localize sounds that we hear first when being subjected to a number of similar sounds coming from all around us.) You can set the Delay time in 5 millisecond intervals from 15 to 30 milliseconds. Although the recommended delay time for Dolby Pro Logic is 20 milliseconds, you can use the remote control to adjust the delay time to best suit your listening room. The front panel and on-screen display both indicate the amount of surround delay time. Use the chart below to best select the surround delay time for your system.
