A Compact, Efficient, and Powerful Amplifier for Any Installation

The Blaze Audio PowerZone Connect 504D is a versatile 500-watt, 4-channel power amplifier with full-matrix DSP and Dante. Utilizing Pascal’s UMAC Class D technology, this unit ensures exceptional sound quality, reliability, and industry-leading efficiency. Its hybrid power distribution allows each channel to be individually configured for either lo-Z or hi-Z operation, reducing the number of units needed for system installations. Moreover, it houses a 4-in/4-out Dante interface for seamless compatibility with AoIP networks. On top of that, power-sharing technology allows you to intelligently distribute the amplifier’s total available power across all its channels, ensuring optimal performance and steadfast reliability. The PowerZone Connect 504D’s robust DSP offers extensive configuration options and tuning features, with an easy setup process via the built-in wireless access point and Blaze Audio’s intuitive PowerZone Control web app. Additionally, this power amplifier includes S/PDIF digital I/O, a configurable GPIO, and an energy-saving UREC universal power supply. Boasting an ultra-compact half-rack form factor, the PowerZone Connect 504D is an outstanding high-performance amplifier for bars, restaurants, retail stores, fitness centers, hotels, educational facilities, corporate environments, and houses of worship.

Seamless setup with PowerZone Control

Configuring the PowerZone Connect 504D is remarkably straightforward, thanks to Blaze Audio’s user-friendly PowerZone Control web app. PowerZone Control enables effortless customization of complex audio and voice systems with a comprehensive array of DSP configuration options and tuning features. These include multizone setup, input mixing, priority and ducking, restriction, input and output EQ, S/PDIF output routing, highpass filter, speaker presets, delay, Wall-S1 controller configuration, sine generator, and more. Best of all, PowerZone Control is embedded directly into the PowerZone Connect 504D, and it can be accessed from any browser-equipped device via the amplifier’s built-in wireless access point.
