Product Overview
Sonos Amp Multi is a four-zone, eight-output amplifier designed to streamline installations and deliver high-quality audio.
Assign each of the eight 125W channels to any zone.
It uses GaN technology for significantly greater power efficiency, consumes 5.4W at idle (with WiFi disabled) which minimizes
heat generation, improves reliability, and eliminates the need for fans. Post-filter feedback (PFFB) enables real-time signal
correction, ensuring exceptional audio clarity, precision, and control across different speaker loads.
The Rack Mount (sold separately) has been designed specifically for Amp Multi, creating space above and below each
unit to support airflow in a 2U configuration. Amp Multi’s flat back makes it easy to stand upright so the Rack Mount slides
on easily. Secure with just four screws for a satisfyingly simple installation. Clear status LEDs provide immediate feedback,
automatically adjusting to the room’s lighting for optimal visibility.
The Sonos app gives you complete control over everthing: zones, sources, output assignments, light indicators, and status
monitoring. Setup is easier than ever thanks to an audible chirp that identifies each unit — no PIN required. Stream up to four
audio sources simultaneously from the Sonos app, Apple Airplay 2, or Spotify Connect, with connection from wired Ethernet
or WiFi 6. Amp Multi provides optimization profiles for Sonos Architectural speakers as well as ProTune, which includes a full
suite of manual controls to optimize each output for each space.
Amp Multi offers true multi-zone flexibility, empowering integrators to deliver bespoke audio experiences.
