Sound field parameter

Features

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.DLY

Initial delay. Presence, surround, and surround back initial delay. Changes the apparent distance

P.INIT.DLY

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

S.INIT.DLY

larger the value, the farther it seems. For a small room, set to a small value. For a large room, set

SB INI.DLY

to a large value.

Control range: 1 to 99 ms (INIT.DLY and P.INIT.DLY)

1 to 49 ms (S.INIT.DLY and SB INI.DLY)
