Blaze PowerZone Connect-504 4-Channel DSP Power Amp

The PowerZone Connect 504 is a modern Class-D amplifier with fully integrated DSP technology. It offers maximum reliability, impressive energy efficiency, and extremely flexible system configuration for professional fixed installations. Designed for a wide range of audio applications in commercial, public, or educational facilities, the amplifier represents a central solution for high-quality, high-performance audio systems.

Flexible support for Lo-Z and Hi-Z speaker systems

The PowerZone Connect 504 is suitable for both low-impedance loudspeakers (4–16 ohms) and constant-voltage 70V or 100V systems. This dual operation capability makes it extremely versatile, allowing the combination of different loudspeaker types within a single system—ideal for mixed installations in larger properties, hotels, or event venues.

The integrated power-sharing technology enables intelligent, dynamic distribution of the total power of up to 1000 watts across all channels. This allows for demand-based power distribution and ensures maximum flexibility without sacrificing performance – regardless of whether the system is operating in Lo-Z or Hi-Z mode.

Compact design – maximum performance in the smallest space

With its slim and space-saving design, the PowerZone Connect 504 fits easily into standard 19" racks and is suitable for installations with limited space. Despite its compact size, it delivers an impressive power output of up to 1000 watts, making it the ideal solution for demanding audio installations with high power requirements.

Powerful web app for system control and DSP configuration

The integrated PowerZone Control web app provides a simple, browser-based user interface for setting up and controlling the amplifier. Without the need for additional software, users can configure all DSP functions directly over the network. These include parametric equalizers, high- and low-pass filters, delay times, limiters, routing options, and presets – ideal for precise adaptation to a wide variety of acoustic requirements.
