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. INIT. DLY)
