The PowerZone™ Connect 1U series is a line of DSP-enabled Class-D amplifiers designed to simplify the lives of system installers, providing unmatched reliability, efficiency, and exceptional system configuration. Their compact form factor makes them an ideal choice for audio/voice installation projects with limited space constraints, demanding high-output performance of up to 1000 W. The 1U family powers both conventional low-impedance (4 Ω to 16 Ω) loudspeakers and constant voltage (70 V/100 V) transformer-coupled loudspeakers, and features automatic power-sharing technology for proportional distribution in both Lo-Z and Hi-Z modes.

Specific models of the PowerZone™ Connect 1U amplifiers offer compatibility with Audinate Dante™ AoIP networks and installations. 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 multizone 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.
