listening room. Not all of the following parameters are found in every program.

Sound field parameter
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
reflection heard by the listener. The smaller the value, the smaller the sound field 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.
