Sonos Amp Multi Targets Pro Installers with Rack-Mounted Design and 24-Speaker Capacity

Sonos has unveiled the Amp Multi, a rack-mountable amplifier designed specifically for professional integrators requiring multi-room audio solutions. Unlike the consumer-focused Sonos Amp, this 2U-form factor device targets commercial installations and high-end residential systems where scalability and centralized control are paramount.

Power and Speaker Configuration The Amp Multi delivers 125 watts per channel at 8 ohms across eight channels. Its unique design allows each channel to power three speakers simultaneously when paired with Sonos' architectural speakers (in-wall or ceiling models), enabling support for up to 24 speakers total. This distributed approach eliminates the need for external speaker selector boxes in multi-room setups.

Engineering and Design To maintain efficiency in its compact chassis, Sonos implemented Class D amplification paired with a gallium nitride (GaN) power supply. GaN technology reduces heat generation and power loss compared to traditional silicon-based power systems, enabling higher power density within the 2U rack footprint. This makes the Amp Multi suitable for installation in space-constrained server racks or AV cabinets.

Zone Control and Connectivity The amplifier organizes speakers into four independently controllable zones via the Sonos app. Each zone supports the addition of one Sonos Sub for enhanced bass response. Streaming capabilities include Apple AirPlay 2, Spotify Connect, and native support for over 100 streaming services. For wired sources, two RCA line-level inputs and a USB-C port accommodate external devices like CD players or turntables.

Professional Deployment Focus Unlike consumer Sonos products, the Amp Multi will only be available through authorized integration partners listed on Sonos' professional installer portal. This channel strategy ensures proper system design and calibration. The Amp Multi integrates with existing Sonos ecosystem features like Trueplay room correction and voice control via Amazon Alexa or Google Assistant.

Market Context The Amp Multi enters a competitive pro-installation market dominated by brands like Crestron and Control4. Sonos differentiates through its consumer-friendly app ecosystem and streaming service integrations while leveraging its residential brand recognition. Pricing remains undisclosed, but expect positioning above the consumer Amp ($789) given expanded capabilities. Installers can request specifications and technical documentation via the official product page.

Practical Implications This release signals Sonos' aggressive push into custom installation markets. For integrators, it simplifies whole-home audio deployments using Sonos' ecosystem while reducing rack space requirements. Homeowners gain access to Sonos' streaming features in architectural installations without needing multiple standalone Amps. The Amp Multi is expected to ship within Q2 2026 through professional AV channels.
