2.4. BGM Broadcasts
These broadcasts are generated by inputting audio signals originating only from BGM player devices into the
SX-2000 system, and are usually sent at relatively low volumes. BGM broadcasting is conducted by first
setting BGM patterns (comprised of various combinations of input channels, broadcast zones, etc.), then
activating these patterns. It is possible to perform settings so that multiple BGM sources are output to multiple
zones using a single BGM pattern. BGM patterns can be activated using the function keys on the front panel
of the SX-2000AI, SX-2100AI, SX-2000AO, or SX-2100AO, the keys on the RM-200SF, RM-200S, RM-
200SA, or RM-210, or the control input (pulse input) on the SX-2000SM, SX-2100AI, SX-2000AO, SX-
2100AO, or SX-2000CI.
To make BGM pattern broadcast, perform each setting using the SX-2000 Setting Software. The setting
procedures are the same as those of general-purpose pattern broadcast. However, there is no need to
perform output zone patterns.
[BGM Pattern Setting Example]
In the example below, the table shows a pattern comprised of several BGM sound sources and broadcast
zones. The input channels of the SX-2100AI (Audio Input Unit) are designated as BGM input sources, while
the output channels of the SX-2000AO (Audio Output Unit) are designated as the zones.
