Stewart Audio AV25-2 2 Channel Subcompact Amplifier

Compact Stereo Amplifier Built for Flexible Commercial Installations
The Stewart Audio AV25-2 is a 2-channel subcompact amplifier delivering 35 watts per channel at 4 ohms and 25 watts per channel at 8 ohms. Housed in a 1/4 rack-width chassis, this Energy Star-compliant amplifier is designed for applications where space is limited but performance and reliability are essential. Ideal for corporate AV systems, education spaces, conference rooms, and hospitality environments, it offers clean power output with built-in smart features to support energy efficiency and control system integration.

Subcompact Form Factor Ideal for Tight Install Locations
Measuring just a quarter rack in width, the AV25-2 fits into spaces where full-size amplifiers can't. Its small footprint makes it easy to install behind displays, under tables, inside lecterns, or in plenum spaces above ceilings. The compact size doesn’t compromise performance—it still delivers consistent stereo output with clarity across a wide frequency range, supporting everything from speech reinforcement to background music systems.

Signal Sense Technology Enables Smart Power Management
The AV25-2 includes Stewart Audio’s Signal Sense Technology, which allows the amplifier to automatically enter a low-power sleep mode when no signal is detected and instantly wake up when audio returns. This feature reduces energy consumption and contributes to Energy Star certification, making the AV25-2 a responsible choice for energy-conscious AV designs in commercial and institutional settings.

Supports Integration with Fire Alarm and Paging Systems
With built-in muting control for both music and emergency paging systems, the AV25-2 is well-suited for environments requiring fire alarm interface or facility-wide announcements. It ensures that background audio is overridden when emergency systems are triggered, aligning with code-compliant commercial audio requirements.

Flexible Mounting Options for Professional Installers
This amplifier is designed for maximum mounting flexibility. Whether you're working with rack rails, wall mounts, under-desk brackets, or pole-mount kits, the AV25-2 adapts to various installation needs. Its lightweight chassis and range of accessories allow for fast, clean setups in diverse environments—from classrooms and digital signage installations to worship spaces and retail audio zones.

Plenum Rated for Above-Ceiling Applications
Thanks to its plenum rating, the AV25-2 meets the safety requirements for installation in air-handling spaces above drop ceilings. This makes it a go-to solution for commercial integrators looking for compliant, high-performance audio gear in buildings with strict fire safety standards.
