Stewart Audio DSP100-2-LZ 2 Channel DSP-Enabled Amplifier

Two-Channel DSP Amplifier Designed for 4/8 Ohm Systems
The Stewart Audio DSP100-2-LZ is a dual-channel amplifier delivering either 50W or 100W per channel into 4 or 8 ohm speaker loads. Housed in a compact 1/2 rack form factor, this amplifier is purpose-built for commercial installations that require high-quality sound, built-in signal processing, and zone-specific control. Whether you're deploying background music in retail or managing AV zones in hospitality or education environments, this amplifier provides the tools and performance needed to get the job done efficiently.

Built-In DSP for Detailed Zone Tuning and Audio Control
With an onboard full-featured DSP, the DSP100-2-LZ enables precise audio configuration per zone. The DSP includes a full cross-point mixer, parametric EQ, high- and low-pass filters, compressors, and limiters. This level of control makes it possible to adjust for varying speaker characteristics, balance frequency response, and handle difficult acoustic environments—all without requiring external processing gear.

Flexible Power Output for Small to Mid-Sized Audio Zones
Each channel of the DSP100-2-LZ can deliver either 50 or 100 watts depending on load, making it suitable for powering a range of speaker setups across commercial audio systems. Whether running 8-ohm surface-mount speakers or 4-ohm ceiling arrays, this amplifier delivers clean, consistent power while maintaining excellent audio fidelity. It’s ideal for small to medium-sized rooms that need strong, reliable amplification.

Analog Inputs for Broad Source Compatibility
The amplifier features two balanced line/mic inputs and two unbalanced RCA inputs, giving you multiple options for connecting audio sources. These can include background music players, microphones, paging systems, or media players. Input flexibility means this amplifier adapts easily to existing analog infrastructure and can support a variety of source types without additional converters.

USB Configuration for Fast Setup and Scalable Deployments
Programming is handled through a USB connection, allowing installers to configure all DSP settings and input routing with compatible software. Once dialed in, configurations can be easily saved and duplicated across multiple amplifiers, making the DSP100-2-LZ especially useful for standardized multi-room or multi-site deployments where audio needs to be consistent across many zones.

Remote Volume Control for Simple User Access
To support easy operation by end users, the amplifier includes support for remote volume control devices. This gives staff or guests the ability to adjust volume locally without interacting with racks or control software. It's a key feature in meeting rooms, restaurants, and classrooms where users need simple, reliable access to adjust audio levels on demand.

Silent Operation and Compact Install-Friendly Design
The fanless, convection-cooled design ensures quiet operation, making it ideal for sound-sensitive environments. Its 1/2 rack width fits easily into small spaces, including under counters, podiums, or inside wall enclosures. Combined with rugged build quality and energy efficiency, the DSP100-2-LZ is a long-term solution for distributed low-impedance audio.
