Description

The SCA and DCA amplifiers are a new addition to the Potter proprietary P-Link device catalog. Potter offers seven variations of amplifiers with wattages up to 100W to support small, medium, and hi-rise applications. The amplifiers have the capability to distribute up to two audio channels simultaneously across multiple speaker zones. Each amplifier is supplied with a stacker terminal block to provide accommodations for 8 Class B or 8 Class A speaker outputs. The SCA and DCA amplifiers offer output power at 25VRMS and 70VRMS.

Up to 31 amplifiers can be linked to the IPA-4000V panel and offer up to 248 Class B or Class A speaker outputs.

The DCA-10025 (Dual Channel, 100W, 25VRMS Amplifier) may be programmed to provide an extraordinary 200W for single channel applications via Potter Fire Panel Programmer.

The 70V-1000 converter module will extend output power to 70VRMS on the DCA dual channel amplifiers. The BUA-1000 backup amplifier provides a failsafe solutions for potential lapse in service and compatible with the DCA dual channel amplifiers.
