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.

The S/PDIF is a 2-channel output that can be used to send either a fixed line-source (2 mono or 1 stereo) out to another amplifier or one or two mixers, or expand a zone with extra amplifiers using a variable S/PDIF lineout signal that follows a stereo zone (or two mono zones).
The S/PDIF is normally used to expand a “zone” with more amplifiers if more power is needed. Up to 4 amplifiers can be linked together. Signal loss can occur if more amps are connected. (Use 75-ohm signal cable as described in the manual)
Yes, when 100-volt outputs are wanted in the web GUI, two output channels are used to achieve High-Z. (see the manual and on the back of the amplifier, how to connect the speaker cables)
The software (Firmware) is already inside the amplifier. Just connect to the amplifier using a web browser (see IP address in the manual), and the configuration can start from any device that has a browser.
The end-user can control the zone volume (gain) via the Wall-S1 wall controller. The installer can use the intuitive installation web app to adjust all input and output gains, set the input sensitivity, and adjust the gain/trim for every input/output.
