Sound field parameter descriptions

You can adjust the values of certain digital sound field parameters so that the sound fields are recreated accurately in your
listening room. Not all of the following parameters are found in every program.
Sound field parameter
Decoder Type
Init. Delay
Sur. Init. Delay
SB. Init. Delay
Room Size
Sur. Room Size
SB. Room Size
Decoder type. Selects the decoder used with the SUR. DECODE or MOVIE programs. See pages 68
and 69 for details.
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.
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. Delay)
1 to 49 ms (Sur. Init. Delay and SB Init. Delay)

Small value = 1 ms
Room size. Presence, surround, and surround back room size. Adjusts the apparent size of the sound
field. The larger the value, the larger the surround sound field becomes. As the sound is repeatedly
reflected around a room, the larger the hall is, the longer the time between the original reflected sound
and the subsequent reflections. By controlling the time between the reflected sounds, you can change
the apparent size of the virtual venue. Changing this parameter from one to two doubles the apparent
length of the room.
y
When you adjust the room size parameters, we also recommend that you adjust the corresponding
initial delay parameters likewise. This adjustment is especially effective for the CINEMA DSP
programs.
