SOUND FIELD PROGRAM PARAMETER EDITING

Sound Field Parameter Descriptions

You can adjust the values of certain sound field parameters so the sound fields are recreated accurately in your listening
room.
Note
• Not all of the following parameters can be found in every program.
INIT.DLY (initial delay)
(P.INIT.DLY — for the presence sound field)
Function: This parameter changes the apparent distance from the sound source by adjusting the delay between the
direct sound and the first reflection heard by the listener.
Control range: 1 – 99 msec
Description: The smaller the value, the closer the sound source seems to the listener. The larger the value, the farther
the apparent distance seems. For a small room, this parameter would be set to a small value, for a large
room, set it to a large value.

Small value = 1 ms
ROOM SIZE
(P.ROOM SIZE — for the presence sound field)
Function: This parameter adjusts the apparent size of the surround sound field. The larger the value, the larger the
surround sound field becomes.
Control range: 0.1 – 2.0
Description: 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.
