Stewart Audio FLX-E-80-4-CV-D 4 Channel DSP-Enabled Amplifier

Four-Channel DSP Amplifier with Dante for 70V and 100V Systems
The Stewart Audio FLX-E-80-4-CV-D is a compact 1/2 rack amplifier delivering four channels of 80 watts each into 70V or 100V speaker systems. It combines high-efficiency power output with built-in DSP, network audio via Dante™, and flexible control interfaces. Built for commercial installations that demand reliable zone-based performance and advanced audio processing, this amplifier simplifies integration while delivering precision across every output channel.

Full DSP Engine with Routing, Mixing, and Processing Tools
The integrated DSP gives installers full control over every aspect of signal routing and shaping. Features include a matrix mixer, parametric EQ, high- and low-pass filters, limiters, and pre-mix level control. These tools allow each channel to be customized to match speaker requirements or room acoustics. Whether it’s for paging, background music, or voice reinforcement, the DSP ensures clarity and control across all zones.

Dante Network Audio for Seamless Digital Integration
The FLX-E-80-4-CV-D supports four channels of Dante™ input and four channels of Dante™ output, making it an ideal component for AV-over-IP installations. It connects easily to Dante-enabled mixers, processors, and other devices over standard Ethernet infrastructure. With AES67 compatibility, it fits into a variety of networked environments, making audio distribution scalable and centrally manageable.

Flexible Analog Inputs for Hybrid System Compatibility
This amplifier includes four analog mic/line inputs, with phantom power available on two channels. That allows it to accept signals from paging microphones, media players, or processors without needing additional converters. The analog-digital hybrid architecture ensures the FLX-E-80-4-CV-D works seamlessly in systems transitioning to networked audio, or those using a mix of source types.

Remote Volume and Serial Control Options for System Integration
Control interfaces include Ethernet for real-time configuration and monitoring, RS-232 for integration with control systems, and RVC (Remote Volume Control) for local user access. These options make it easy to integrate the amplifier into a variety of systems, from centralized enterprise AV to independently controlled rooms. Whether programmed via network or controlled by end users, adjustments are efficient and reliable.

Silent Operation in a Space-Saving Format
With convection cooling and no internal fan, the amplifier runs silently, making it ideal for conference rooms, education facilities, or worship spaces. Its 1/2 rack chassis provides installation flexibility, fitting into tight equipment racks, ceiling spaces, or under-cabinet mounts. Despite its compact footprint, it delivers full-scale commercial audio performance.
