Stewart Audio DPA-220+ PowerCore™ Audio Amplifier

Compact Dante PoE Amplifier with Built-In DSP and Real-Time Monitoring
The Stewart Audio DPA-220+ PowerCore is a high-performance PoE audio amplifier designed for networked AV systems where space, power, and performance matter. Delivering 2x20W into 4/8Ω stereo loads or 1x40W into a single 4/8Ω speaker, this Dante-enabled amplifier offers full DSP processing, remote configuration, and real-time system monitoring—all within a compact, plenum-rated chassis. Built for commercial installations, the DPA-220+ operates over a single Ethernet connection, making it ideal for modern AV environments like conference rooms, classrooms, retail zones, or hospitality spaces.

Dante Audio Networking with Auto Scaling Power over Ethernet
This amplifier supports PoE, PoE+, and PoE++ with automatic power negotiation and load sensing during startup. It draws only what’s needed from the network switch or midspan injector and scales its output based on the available power. Whether you need stereo background music or a mono paging channel, the DPA-220+ intelligently adjusts to deliver reliable audio output without external power supplies—simplifying cable runs and reducing install costs.

Advanced DSP Processing for Flexible Audio Control
The DPA-220+ integrates a robust DSP engine offering volume control, EQ, mixing, limiting, compression, and other advanced audio adjustments right from an embedded web server. These features provide granular control over the audio path, ensuring clear, balanced sound in a wide range of acoustic environments. It also supports API and Symetrix Intelligent Module integration for seamless control in automated AV systems.

Real-Time Speaker Monitoring and System Status Feedback
This amplifier goes beyond simple output. It includes speaker load monitoring that measures output voltage, current, impedance, and system temperature in real time. These diagnostics help identify potential speaker faults or system stress before they affect performance. Multi-color LED indicators and a beacon/strobe function allow for easy identification and troubleshooting during system maintenance.

Web-Based Configuration with OTA Firmware Support
Initial setup and updates are simple, thanks to the DPA-220+’s built-in web server and support for over-the-air firmware updates. From device naming to audio routing and output tuning, all configuration is handled remotely through a browser. This makes it easy for AV integrators to manage devices across large-scale deployments without the need to physically access each unit.

Built for Durability in Ceiling and Hidden Installations
With its plenum-rated enclosure and included hanger wire strap, the DPA-220+ is ready for above-ceiling and out-of-sight installs in code-compliant commercial spaces. The rugged, compact form factor allows for discreet placement in digital signage, collaborative workspaces, or any location with limited real estate. It’s engineered to perform reliably in continuous-duty applications.
