sent both to the channel A power amp and the channel

B power amp. In this case, loads are automatically

connected between the A and B input terminals.

• BRIDGED mode

In BRIDGED mode, channels A and B operate simul-

taneously, functioning as a single mono ampliﬁer.

Note: When in PARALLEL and BRIDGED modes,

input terminals A and B are shorted auto-

matically. Make sure not to input an audio

signal to an inactive input terminal.

monitoring or remote control. Refer to "MONITOR/
