■ Delay Time Setting (fs step)
1. D1 or D2 delay time setting of Function2
2. Delay time setting of each FL, FR, RR, RL, NL and NR channel
Lch input
FL
RL
NL
Delay Memory 1word=24bit
18ms Delay = 794word (44.1kHz x 0.018)
Rch input
FR
RR
NL
Delay Memory 1word=24bit
18ms Delay = 794word (44.1kHz x 0.018)
(1/fs = 1/44100 = approximately 0.0226ms)= one unit.

Data 2 (2byte) Front R1 out delay time
Delay time: 1/fs unit R/W
Set range (0x0000~0x031A)
Data 3 (2byte) Rear R2 out delay time
Delay time: 1/fs unit R/W
Set range (0x0000~0x031A)
