2-channel Broadcast &
Cable Extension
Booster Power Amplifier
WA-BA240N
Output Power : 240W
Input : Line/100V
Output : 100V/70V
This 240W monaural amplifier delivers 100V/70V to drive high-impedance speakers and can also be used with low-
impedance speakers and is equipped for both line and 100V input. Addition of this one unit is all that is required for
2-channel broadcast. It can also be used as a booster amplifier in cable extension applications.
Addition of an Booster Power Amplifier permits cable extension to deliver sound to distant locations.
Cable Extension
When you need to broadcast to distant locations, the optional Booster Power Amplifier allows you to extend the
speaker cable as far as necessary.
