Sound field parameter Features

DSP LEVEL

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

P.INIT.DLY

S.INIT.DLY

SB INI.DLY

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. DLY and P. INT. DLY)

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