Intelligent Audio Ampliers
Signature Series ampliers are high-ecien-
cy switch mode audio ampliers available
in 30 and 50 watt sizes. Amplifiers have
two input channels supporting dual chan-
nel or single channel audio applications.
Signature amplifiers are ideally suited for
distributed audio applications and small
centrally banked applications. The audio
output is congurable as 25Vrms or 70Vrms in Class B or Class A wiring congurations. Speakers can connect directly
to the output of the amplier or the amplier output can run as an audio riser to Signature modules where speaker zone
selection is made. Each amplier has a built-in 1kHz tone generator and provision for a back up amplier. On-board
status LEDs provide quick visual indication of amplier status.
