Sonos Amp Multi Multizone Streaming Amplifier

Description

The Sonos Amp Multi is a professional-grade multizone streaming amplifier engineered for large-scale residential and commercial audio installations. Designed specifically for custom integrators and whole-home audio systems, the Amp Multi combines powerful amplification, flexible zone management, and advanced DSP tuning into a compact rack-friendly design.

Featuring eight amplified outputs with 125 watts per channel at 8 ohms, the Amp Multi can power up to four independent audio zones simultaneously. Each output can be configured independently in stereo or mono, providing exceptional flexibility for multiroom music systems, distributed audio, hospitality spaces, and luxury home automation projects.

Built using advanced GaN (Gallium Nitride) amplification technology and post-filter feedback (PFFB), the amplifier delivers highly efficient, low-distortion performance with improved thermal management and fanless operation. Sonos ProTune technology further enhances installation flexibility by providing a 10-band parametric EQ along with gain and delay controls for room-specific audio tuning.

The Amp Multi integrates seamlessly into the Sonos ecosystem, allowing wireless streaming, multiroom synchronization, and control through the Sonos app. Support for Apple AirPlay 2, Spotify Direct Control, and smart home integrations makes it ideal for modern connected homes and commercial environments.

Designed specifically for rack installations, the amplifier features a thermally optimized chassis, recessed connectors, clean cable management, and optional 2U rack mounting accessories for professional deployment.
