Stewart Audio FLX-E-320-1-CV Digital Matrix Processor

Single-Channel DSP Amplifier for High-Power 70V/100V Audio Systems
The Stewart Audio FLX-E-320-1-CV is a single-channel amplifier built for demanding commercial environments requiring reliable high-power audio distribution. Delivering 320 watts into 70V or 100V speaker lines, this amplifier combines a compact footprint with full DSP functionality and robust control options. Designed for installations that prioritize power, precision, and configurability, it supports flexible integration into retail spaces, hospitality venues, education campuses, or corporate facilities.

Integrated DSP Engine with Advanced Signal Processing
At the core of the FLX-E-320-1-CV is a full-featured digital signal processor built to address zone-based audio challenges with precision. It includes a cross-point mixer, EQ, high- and low-pass filters, ducking, compression, limiting, and pre-mix level control. These DSP blocks provide everything needed to optimize and manage audio signals before amplification. Whether balancing multiple input sources or adapting to unique room acoustics, the onboard processing ensures audio clarity and consistency.

Streamlined Ethernet Control for Programming and Monitoring
The FLX-E-320-1-CV supports Ethernet-based configuration and monitoring, allowing integrators to program and manage settings remotely. With real-time system reporting, this feature improves efficiency for both setup and long-term maintenance. Whether used across a campus or within a centralized rack system, the Ethernet interface allows for easy duplication of settings across multiple amplifiers in large-scale deployments.

Support for Remote Volume and RS-232 Control Interfaces
In addition to Ethernet, the amplifier includes RVC and RS-232 support for integration with third-party control systems and wall-mounted volume controls. This means facility staff or users can easily adjust volume levels without accessing the amplifier directly. It’s especially beneficial in environments where zones are managed independently, like conference rooms, classrooms, or multipurpose halls.

Compact Half-Rack Format with Quiet Operation
The FLX-E-320-1-CV is housed in a 1/2 rack-width chassis with convection cooling, providing silent operation for sound-sensitive areas. This compact form factor allows for easy installation into AV racks, ceilings, furniture, or lecterns without occupying unnecessary space. Despite its small size, the amplifier delivers professional-grade performance and reliability across a range of commercial AV applications.

Optional Dante Integration for AV-over-IP Networks
While this model does not come with Dante as standard, it includes support for an optional Dante™ audio network interface. This expands the system’s compatibility with AV-over-IP infrastructure, enabling digital audio routing across networked systems for future-ready installations. With the optional upgrade, the amplifier becomes even more flexible for scalable and centralized AV environments.
