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

Networked DSP Amplifier with Dante and Low-Z Compatibility
The Stewart Audio FLX-E-80-4-LZ-D is a four-channel amplifier designed for 4Ω and 8Ω speaker systems, delivering 80 watts per channel into 4 ohms and 40 watts per channel into 8 ohms. Built into a compact 1/2 rack enclosure, this unit is engineered for commercial applications that demand flexible zone control, high-performance audio, and advanced integration. With built-in DSP, Ethernet setup, RS-232 control, and Dante™ network audio, the FLX-E-80-4-LZ-D covers a wide range of installation needs.

Powerful DSP Engine for Full Signal Processing Control
A full-function DSP engine powers this amplifier, offering audio routing and optimization directly onboard. Each channel benefits from matrix mixing, EQ, high-pass and low-pass filters, limiters, and pre-mix gain settings. These processing tools are essential for refining system performance in spaces with complex acoustic requirements or varied speaker setups—no need for external DSP units.

Dante Audio Network Integration for Scalable System Design
This model includes four Dante input channels and four Dante output channels, making it an ideal solution for AV-over-IP infrastructure. Use it as part of a digital signal path with other Dante-enabled components, or integrate it into a larger AES67-compatible network. The Dante architecture simplifies audio distribution, reduces cable runs, and keeps your system future-ready.

Flexible Analog Inputs with Phantom Power Support
Four analog inputs are included, each configurable for mic or line level, with phantom power available on two channels. This enables direct connection to microphones, media sources, or legacy systems while maintaining flexibility in routing via the internal DSP. The hybrid analog/digital input structure supports a smooth transition between traditional and networked audio systems.

Comprehensive Remote Control Options via Ethernet and RS-232
Control and monitoring are available through the built-in Ethernet port, providing access to amplifier settings and status for installers or system managers. RS-232 and RVC (Remote Volume Control) support extend control options to third-party systems and wall-mounted interfaces, giving users flexible access to volume and preset recall.

Silent, Space-Efficient Design for Discreet Installation
Designed for environments that demand quiet operation and compact hardware, the FLX-E-80-4-LZ-D uses convection cooling and a 1/2 rack form factor. This makes it suitable for installations in furniture, ceilings, or AV cabinets where fan noise or space limitations are a concern. Despite its small size, it delivers dependable, full-featured amplification for multi-zone systems.
