SB INI.DLY 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 listener.

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.
