The Sound Town NIX-A48PRO is a compact yet powerful 2U rack-mountable class AB 4-channel amplifier. Engineered for high-powered output, it delivers 4 x 1200W RMS (8Ω Stereo), 4 x 1800W RMS (4Ω Stereo), and 2 x 2400W RMS in bridged-mono mode (8Ω), catering to diverse audio needs. The NIX-A48PRO shines in connectivity, featuring 4 XLR inputs and outputs, 4 Speakon, and 4 sets of binding post output connectors, ensuring seamless integration with various audio setups.

Prioritizing safety, the amplifier comes equipped with overload, overheating, and short-circuit protection, including a fuse holder and LED indicators. A 3-second start delay and built-in limiter are integrated to prevent distortions and ensure smooth activation. Its front-panel LCD screen display allows for easy monitoring of signal levels, modes, and temperatures for each channel.

Flexibility is key with the STEREO/PARALLEL/BRIDGE switch, offering customizable signal flow. The bridge-mono mode doubles output power for more robust audio output, while selectable sensitivity (0.77V/1.0V/1.4V) allows customization to match gear specifications. The NIX-A48PRO’s rugged construction and reliability make it ideal for touring applications.
