Initial delay. Presence, surround, and surround back sound field initial delay. Changes the 
apparent distance from the source sound by adjusting the delay between the direct sound and the 
first reflection heard by the listener. The smaller the value, the closer the sound source seems to 
the reflection face.
y
When you adjust the initial delay parameters, we also recommend that you adjust the 
corresponding room size parameters likewise. This adjustment is especially effective for the 
CINEMA DSP programs.
Control range: 1 to 99 ms (INIT.DLY and P.INIT.DLY)
