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 or MOVIE programs. See
pages 84 and 85 for details.
DSP Level
DSP level. Adjusts the level of all the DSP effect sounds within a narrow range. Depending on
the acoustics of your listening room, you may want to increase or decrease the DSP effect level
relative to the level of the direct sound.
Control range: –6 dB to +3 dB
Init. Delay
Sur. Init. Delay
SB Init. Delay
Initial delay. Presence, surround, and surround back initial delay. Changes the apparent distance
from the source sound by adjusting the delay between the direct sound and the first reflection
heard by the listener. The smaller the value, the closer the sound source seems to the listener. The
larger the value, the farther it seems. For a small room, set to a small value. For a large room, set
to a large value.
Control range: 1 to 99 ms (Init. Delay)
1 to 49 ms (Sur. Init. Delay and SB Init. Delay)
