■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 | Features | |
parameter | ||
| ||
Decoder Type | Decoder type. Selects the decoder used with the SUR. DECODE, THX, or MOVIE programs. See page 72 for details. | |
|
| |
Init. Delay | Initial delay. Presence, surround, and surround back sound field initial delay. Changes the apparent size of the sound field by adjusting the | |
Sur. Init.Delay | 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 | |
SB. Init. Delay | 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. | |

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.
Control range: 0.1 to 2.0
