8.1. General Description
Use the matrix mode when broadcasting BGM or paging calls to zoned areas in such facilities as civic centers,
universities, schools, restaurants, bars, and cruise ships.
Input signals are basically not mixed but distributed in the matrix mode.
Three operation methods are available in this mode; Normal matrix operation, 1-channel output operation (A-
9060S/9120S/9240SH only), and 2-channel output operation (BGM/Page operation) (A-9060DH/9120DH
only). (Refer to p. 36 "SELECTING OPERATION METHOD.")
8.1.1. Normal matrix operation
In the normal matrix operation method, multiple audio input signals can be simultaneously routed to multiple
outputs and in addition, paging calls assigned different priority levels can be initiated during BGM broadcast to
each zone.
The ducker function (refer to p. 28 "Glossary") also allows paging calls to be made without interrupting BGM
broadcasts to each zone.
A maximum of 32 settings related to broadcasts, such as broadcast sound source input channels, interrupt
broadcast output channels, BGM source input channels, and broadcast start methods, can be stored as Event
memory.
