8.1.2. 1-channel output operation
This operation method can be selected when the A-9060S, A-9120S, or A-9240SH Amplifier without T-001T Audio Output Expansion module installed is used. Audio signals are delivered only at the amplifier's output channel 1. Paging calls and BGM broadcasts are made on the basis of the priority levels set for input channels. In conjunction with the optional ZP-001T Zone Paging module and the optional SS-9001 Speaker Selector, the output channel 1's signals can be distributed to 4 zones.
(State where relays for ZONE 1 and 4 are activated)

8.1.3. 2-channel output operation (BGM/Paging operation)
This operation method can be selected when the A-9060DH or A-9120DH Amplifier with ZP-001T Zone Paging module but without T-001T Audio Output Expansion module installed is used. BGM broadcasts*1 are delivered at the amplifier's output channel 1 and priority broadcasts*2 at the output channels 2. Priority broadcasts are based on the priority levels set for input channels. BGM broadcasts are always made to all zones as long as no priority broadcasts are made.
