FOR-A FA-9520 Operation Manual page 180

Setting Examples:
 When setting all channel pairs CH 1/2 to 7/8 to Group A
CH 1/2 will be the reference. Other channel pairs will be synchronized to the word clock of
CH1/2.
 When setting channels CH1/2 to 3/4 to Group A, and channels CH5/6 to 7/8 to Group
B
CH 1/2 will be the reference pair for Group A, and CH 5/6 the reference pair for Group B.
Channel pairs in an audio group must be synchronous and must have the same
sampling rate. Changing the audio assignment of the reference channel pair may
cause noise on other channel pairs in the same audio group.
Also, changing the assignment may affect the phase alignment of the reference
channel pair and other channel pairs. If the alignment is turned off, set Master Mute
(see section 9-3-8 "Audio Master Gain Settings") to on and off, or turn the unit power
off and on to regain the alignment.
