Edwards SIGA-AA50 Intelligent Audio Amplifier (New)

Edwards SIGA-AA50

SIGA amplifiers are high-efficiency switch-mode audio amplifiers available in 30 and 50-watt sizes. Amplifiers have two input channels supporting dual channel or single channel audio applications. Amplifier project application flexibility is enhanced by provision for input levels at 1Vrms or 25Vrms. This allows SIGA amplifiers to obtain their input from a line-level signal or the output of an other 25Vrms amplifier. This feature provides great application flexibility, helping meet project requirements. Input channel selection is made through software programming and transmitted to the amplifier via a signature data circuit. This reduces wiring interconnect requirements by reducing the number of control modules needed.

Each amplifier has a provision for connecting backup amplification.
Amplifiers can be backed up one-to-one, or multiple amplifiers can have one shared backup amplifier. Each SIGA amplifier has an onboard 1kHz tone generator. That can activate in the event of input failure or if no backup amplifier is available.

Standard Features
Remote or Local mounting
Two channel input
Connects to signature data circuit. Allows switching between two channels without additional control modules. Eliminates the need for additional amplifier monitoring.
Output selectable as 25Vrms or 70Vrms
Dual input level allows the use of a 1Volt or 25Volt input signal.
Backup amplifier connection
Back up 1kHz tone generator
