aking Public Address to the Next Level.
Addition of Booster Power Amplifier enables 2-channel
broadcast with separate transmissions delivered to different zones.
2-channel
Broadcast
For example, a business-related message is transmitted
only to Zone 1 while background music continues to be
played throughout the building. Background music
continues in Zone 2 and Zone 3.

Up to 10 units can be connected to increase capacity to 30 zones.
Add Up To 30 Zones
Each WA-MA120N (or WA-MA240N) can drive three
output channels. As indicated in the diagram on the right,
a system in which a single source drives up to 30 Zones
can be constructed.
