Stewart Audio FLX-E-320-1-CV-D Mono DSP-Enabled Amplifier

Mono DSP Amplifier with Dante Network Audio for 70V/100V Systems
The Stewart Audio FLX-E-320-1-CV-D is a single-channel commercial-grade amplifier delivering 320 watts of power into 70V or 100V speaker systems. Designed for installations that demand both high-output and advanced signal control, this amplifier integrates full DSP capabilities, Dante™ audio networking, and multiple control interfaces into a compact 1/2 rack format. It’s an ideal solution for distributed audio zones in conference facilities, airports, universities, and retail environments where precision and reliability are essential.

Integrated DSP Processing for Advanced Audio Optimization
This amplifier includes a built-in digital signal processor engineered to handle a wide range of audio management tasks. The onboard DSP features a full cross-point mixer, filters, EQ, pre-mix level control, limiting, and dynamic processing. These tools allow installers to optimize signal flow, tailor output to match room acoustics, and protect speakers across various zones. The all-in-one design eliminates the need for external processing hardware, reducing system complexity and installation time.

Dante Audio Networking for Scalable Digital Systems
The FLX-E-320-1-CV-D supports four Dante input channels and four Dante output channels, making it fully compatible with Dante and AES67 audio-over-IP environments. This enables seamless integration into networked audio systems, allowing digital audio to be routed over standard Ethernet infrastructure. With Dante, the amplifier becomes part of a scalable and flexible signal distribution architecture, ideal for facilities that require centralized routing, audio zone expansion, or future-ready AV integration.

Flexible Analog Inputs and Control Options
In addition to network audio, the amplifier includes four analog inputs, all selectable as mic or line level, with phantom power available on two of them. This flexibility allows integration with legacy analog sources like paging microphones, media players, or control processors. Control interfaces include Ethernet for configuration and monitoring, RS-232 for third-party system integration, and RVC (Remote Volume Control) support for localized access. This versatility ensures compatibility with a wide range of control environments.

Compact and Silent for Versatile Installation Scenarios
With its convection-cooled, fanless enclosure, the FLX-E-320-1-CV-D operates silently and is suitable for installation in noise-sensitive environments. Its 1/2 rack format allows it to be mounted in small AV cabinets, behind displays, under podiums, or above ceilings. This space-saving design, combined with robust power output and processing, makes the amplifier ideal for locations where performance and form factor both matter.

Optimized for High-Power Zone Applications
This amplifier is purpose-built for single-zone applications requiring high-output 70V or 100V amplification, such as auditoriums, gymnasiums, and large retail floor spaces. With its combination of Dante audio routing, DSP customization, and centralized control, the FLX-E-320-1-CV-D provides integrators with a flexible and efficient solution that meets modern AV installation standards.
