Blaze POWERZONE 504 1U Class D 4 Channel Power Amplifier 500 Watts The PowerZone? Connect 1U series is a line of DSP-enabled Class-D amplifiers designed to make system installers? lives easier, offering unparalleled reliability and efficiency, along with exceptional system configuration. The ultra-compact form factor, makes them an ideal choice for audio/voice installation projects with limited space constraints that demand high-output performance. The 1U family powers both conventional low-impedance (4? to 16?) loudspeakers and constant voltage (70V/ 100V) transformer-coupled loudspeakers, and features automatic power-sharing technology for proportional distribution in both Lo-Z and Hi-Z modes. Our intuitive PowerZone? Control web app is built into all our PowerZone? Connect amplifiers for easy system setup. PowerZone? Control facilitates effortless customization of even the most challenging audio/voice systems by delivering many DSP configuration options and tuning features, including multi-zone setup, input mixing, priority and ducking, restriction, input and output EQ, S/PDIF output routing, high-pass filter, speaker presets, delay, Wall-S1 controller configuration, Sine generator, and much more.
