Stewart Audio FLX-E-160-2-LZ Digital Matrix Processor

Two-Channel DSP Amplifier for 4/8 Ohm Systems with Ethernet Control
The Stewart Audio FLX-E-160-2-LZ is a compact, high-performance amplifier delivering 160 watts per channel into 4 or 8 ohm speaker loads. Designed for commercial installations where low-impedance systems are required, this 1/2 rack amplifier combines robust power output, integrated DSP processing, Ethernet configuration, and multiple control options into a single efficient unit. It's an ideal solution for zones requiring detailed control, flexibility, and reliable performance across hospitality, retail, education, and corporate AV environments.

Full-Featured DSP for Customizable Audio Control
The onboard DSP provides extensive control over input and output processing with a full cross-point matrix mixer, parametric EQ, high- and low-pass filters, limiters, and pre-mix level adjustments. These tools allow integrators to fine-tune every aspect of the signal path, ensuring clear, balanced audio performance tailored to the acoustic needs of each room or speaker type. This built-in processing removes the need for external signal processors and simplifies the signal chain.

Multiple Input Options for Versatile System Integration
The FLX-E-160-2-LZ includes four analog inputs, all configurable as mic or line level, with phantom power available on two of them. This allows the amplifier to support microphones, media players, paging systems, and other analog sources with ease. Whether you’re distributing music, paging announcements, or speech reinforcement, this flexible input structure adapts to your system design.

Network and Serial Control for Simplified Management
Control and monitoring are handled via Ethernet, allowing for real-time status reporting, remote configuration, and simple integration into IP-based systems. The amplifier also supports RS-232 control and remote volume control (RVC), enabling smooth integration with third-party control systems and wall-mounted volume interfaces. This variety of control options gives installers and facility managers flexibility in how the system is accessed and adjusted.

Efficient Performance in a Compact Form Factor
Built into a convection-cooled, fanless half-rack enclosure, the FLX-E-160-2-LZ is designed for silent operation, making it ideal for quiet environments such as conference rooms, boardrooms, and lecture halls. Its compact footprint fits easily into standard racks, podiums, or above-ceiling spaces, allowing it to blend into both visible and hidden installations without sacrificing functionality or power.

Optimized for Small to Medium Zone Applications
This amplifier is specifically engineered for installations that use 4 or 8 ohm loudspeakers and require localized processing and amplification. Its dual 160W output makes it ideal for powering speaker zones that demand higher fidelity and dynamic range than traditional constant voltage systems can provide. It delivers clarity and control where sound quality cannot be compromised.
