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

Two-Channel DSP Amplifier for 70V and 100V Commercial Audio Systems
The Stewart Audio DSP100-2-CV is a 2-channel constant voltage amplifier delivering 100 watts per channel at 70V or 100V. Housed in a compact 1/2 rack enclosure, this amplifier is built to power and control two independent zones with precise DSP tuning and flexible input routing. Ideal for commercial installations like conference centers, hospitality venues, retail stores, and educational campuses, the DSP100-2-CV offers high-performance audio processing in a space-saving, energy-efficient package.

Independent DSP Control for Each Audio Zone
Each channel of the DSP100-2-CV is supported by a full-featured digital signal processor that allows for complete audio customization. The onboard DSP includes a cross-point mixer, equalization, filtering, limiting, and compression. This allows integrators to tailor each output for different loudspeaker types, room acoustics, or audio content. Whether you’re running music in one area and paging in another, the DSP100-2-CV gives you precise control over both.

Analog Input Options with Flexible Routing
The amplifier features two balanced line/mic inputs and two unbalanced RCA inputs, giving it the flexibility to accommodate a variety of audio sources. Inputs can be routed to either channel or mixed as needed, allowing you to run different content to each zone or duplicate the same source across both channels. This adaptability is key for facilities managing background music, announcements, or media playback across multiple rooms.

Simple USB Setup with Repeatable Configuration
Programming the DSP100-2-CV is quick and straightforward via the USB port. Installers can connect directly to configuration software to adjust DSP parameters and input routing, then replicate those settings across multiple units. This feature is especially helpful for contractors handling multi-zone systems or franchise installations where audio needs to be consistent across multiple locations.

Remote Volume Control for User-Friendly Operation
Designed for commercial environments where user interaction is needed, the DSP100-2-CV supports external remote volume control. This allows non-technical staff to manage audio levels from simple wall-mounted interfaces without needing access to the equipment rack. It’s a valuable feature in hospitality, education, and meeting spaces where staff need reliable and convenient control over local volume.

Quiet Operation and Plenum-Safe Installation
Built with convection cooling, this fanless amplifier operates silently, making it suitable for quiet environments such as offices or conference rooms. Its compact size and code-compliant design also allow for installation in plenum spaces above ceilings, making it easy to conceal hardware while meeting safety requirements for commercial buildings.
