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

Two-Channel DSP Amplifier with Dante for 4/8 Ohm Systems
The Stewart Audio DSP100-2-LZ-D is a dual-channel amplifier delivering 100 watts per channel into 4 or 8 ohm speaker loads, with full onboard DSP and Dante™ network audio capability. Designed for professional audio installations where reliability, control, and flexibility are critical, this amplifier provides outstanding performance for small to medium zones. From corporate AV to hospitality, education, or retail environments, the DSP100-2-LZ-D offers the tools integrators need for high-quality, networked sound.

Dante Integration for Digital Audio over Ethernet
Equipped with two Dante input channels, the DSP100-2-LZ-D allows seamless integration into networked AV systems. Audio can be routed over standard Ethernet infrastructure without the need for traditional analog cabling. This reduces complexity, simplifies installation, and enables scalable distribution across multiple rooms or buildings. It’s an ideal solution for AV-over-IP environments that require flexibility and low-impedance speaker support.

Onboard DSP Processing for Zone Optimization
A full-featured DSP engine is built into the amplifier, offering precise audio control. It includes a cross-point mixer, parametric EQ, high- and low-pass filters, dynamic compression, and limiting. These tools enable installers to fine-tune each output channel for speaker type, room size, or specific acoustic conditions. With onboard processing, there’s no need for external DSP hardware, which simplifies the system design and reduces cost.

Multiple Input Options for Hybrid Source Compatibility
In addition to networked audio, the amplifier includes two balanced analog inputs and two unbalanced RCA inputs, making it suitable for systems with legacy or analog sources. This combination allows you to mix digital and analog inputs across both channels, giving you the flexibility to work with media players, microphones, and paging systems alongside networked content from Dante-enabled devices.

USB Configuration for Fast Setup and Easy Replication
Configuration is managed via USB, making it quick to set up and simple to duplicate across multiple units. Using compatible software, installers can adjust DSP parameters, routing, and input levels, then replicate the same settings for consistent performance across large-scale systems or multi-zone deployments. This feature saves time and ensures reliable, repeatable results.

Remote Volume Control Support for End-User Convenience
The DSP100-2-LZ-D supports remote volume control, allowing users to adjust levels from wall-mounted controllers or compatible devices. This enables intuitive access to volume adjustment in areas like conference rooms, classrooms, and restaurants without requiring interaction with rack-mounted equipment or technical interfaces.

Silent, Compact, and Installation Friendly
With a convection-cooled design and 1/2 rack form factor, the DSP100-2-LZ-D operates silently and fits easily into tight or concealed spaces. It’s well suited for plenum installations, podiums, under counters, or AV racks where quiet, compact equipment is needed. The amplifier is also built in the USA, ensuring quality and long-term reliability for commercial AV environments.
