Experience exceptional performance in a compact design with the Redback 15W PA Amplifier, ideal for smaller PA system applications. Engineered with a robust National TDA1519 monolithic IC, this amplifier ensures virtually “destruction-proof” operation, capable of withstanding severe misuse such as over-temperature, over-voltage, overload, and short-circuit speaker line conditions.

This amplifier remains extremely stable even when microphone (balanced line) and speaker cables are run together over long distances. It features an automatic shutdown when severely overloaded, resuming normal operation once the fault condition is removed. Versatile and adaptable, it can be used as a standalone desk/bench unit or rack-mounted with optional hardware. Up to two units can fit side by side in 1RU of rack space (44mm high). Its 12V DC operation (includes M8936 plug pack) makes it perfect for tour buses and mobile installations.
