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

The Stewart Audio DSP100-2-CV is a compact, professional 2-channel Class D DSP-enabled amplifier designed for commercial distributed audio systems. It delivers 100W per channel at 70V/100V, making it ideal for powering two independent audio zones while providing integrated DSP processing to optimize loudspeaker performance and compensate for room acoustics.

Its built-in DSP includes cross-point mixing, EQ, filters, limiters, and other processing functions, while USB programming makes configuration quick and repeatable. The amplifier also supports Dante™ network audio, remote volume control, and external mute functionality.

Technical Specifications

Integrated DSP

The DSP100-2-CV combines amplification and digital signal processing in a single compact unit. Its DSP can be used to optimize the connected loudspeakers and address acoustic challenges within individual zones.

Key DSP functions include:

• Cross-point mixer
• Equalization (EQ)
• Filters
• Limiters
• Signal routing
• Level optimization
• Zone-specific audio processing

This makes the amplifier particularly useful where different rooms or zones require individual audio settings.

Two-Zone Audio Solution

With two 100W output channels, the DSP100-2-CV can power two separate 70V/100V audio zones. Each zone can be configured and optimized according to its speaker arrangement and acoustic requirements.

For example:

Zone 1: Conference Room
Zone 2: Reception / Lobby

This makes it a practical solution for commercial facilities that need independent audio distribution without installing separate amplifiers for every zone.

USB Configuration

The integrated USB programming interface simplifies amplifier setup. Installers can configure the DSP quickly and reproduce the same settings across multiple amplifiers, which is especially useful for larger commercial installations.

Dante™ & Network Audio

The amplifier supports two Dante™ input channels through the optional network input configuration. Dante allows compatible audio sources to be transported over an Ethernet network, simplifying audio distribution in larger AV installations.

Remote Control & Integration

The DSP100-2-CV provides multiple control options:

• 0–10VDC remote volume control
• External contact-closure mute
• USB programming
• Trim controls

This allows the amplifier to integrate with a variety of commercial AV control systems.

Key Benefits

Two-Channel Architecture: Provides 100W per channel for two independent 70V/100V zones.

Built-In DSP: Eliminates the need for separate signal-processing hardware in many installations.

Professional Audio Quality: A >100dB signal-to-noise ratio and <0.1% THD+N provide clean, reliable audio performance.

Quiet Operation: Fanless convection cooling makes it suitable for conference rooms, classrooms, offices, and other noise-sensitive environments.

Compact Design: The 1/2-rack enclosure provides substantial amplification and DSP capability in a small footprint.

Easy Configuration: USB programming enables fast setup and repeatable configurations across multiple installations.
