SB INIT.DLY Initial delay. Presence, surround, and surround back sound field initial delay. Changes the
apparent size of the sound field by adjusting the delay between the direct sound and the first

corresponding room size parameters likewise. This adjustment is especially effective for the
CINEMA DSP programs.
