By controlling the time between the reflected sounds, you can change the apparent size of the virtual venue.

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
Features
Decoder Type
Decoder type. Selects the decoder used with the SUR. DECODE, THX, or MOVIE programs. See page 86 for details.
Init. Delay
Sur. Init.Delay
SB. Init. Delay
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)
Room Size
Sur. Room Size
SB. Room Size
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.
