The Sonos Amp Multi is a 24‑channel professional‑grade streaming amplifier that delivers up to four 125 W channels and eight 30 W channels, all controllable via the Sonos app. Designed for demanding audiophiles and home‑audio installers, it combines high‑power output, automatic DSP optimization, and scalable networking for complex residential audio systems.
What Is the Sonos Amp Multi?
At its core, the Amp Multi is a digital power platform capable of driving up to 24 passive loudspeakers simultaneously. It expands on the original Sonos Amp by offering four independent 125 W channels plus eight 30 W channels that can be paired for 60 W stereo outputs, giving installers a versatile toolbox for ceiling‑mounted, wall‑mounted, or bookshelf speakers.
Power Architecture and Channel Flexibility
- Four high‑power 125 W channels (8 Ω) for demanding drivers.
- Eight auxiliary 30 W channels (8 Ω) that can be bridged into four 60 W stereo pairs.
- Scalable design – multiple Amp Multi units can be networked to support larger homes or multi‑zone projects.
Automatic DSP and Speaker Compatibility
The built‑in digital signal processing automatically calibrates crossover points, equalization, and delay for Sonos Architectural speakers, while also supporting any third‑party passive speakers. All configuration, zoning, and source selection remain within the familiar Sonos app, preserving the brand’s signature simplicity.
Target Users and Market Position
Sonos positions the Amp Multi for high‑end audiophiles and professional home‑audio installers who need a single, app‑driven solution for large speaker arrays. By offering a scalable, networked architecture, the product competes directly with traditional AV‑over‑IP systems and signals Sonos’s move into the custom‑install market.
