Product Overview

Product Overview

Precision-Built for Professionals

Backed by thousands of hours of research and engineering, Amp Multi was built from the ground up to streamline professional installation at every stage. It’s designed to support your workflows and help you deliver bespoke audio experiences with precision and efficiency.

Multi-Zone Flexibility

Each output can be assigned to any zone, giving you complete flexibility in system design. Users can easily change audio sources and content, ensuring a seamless, consistent experience.

Innovation from The Inside and Out

Advanced GaN technology, Class D amplification, and post-filter feedback (PFFB) deliver exceptional audio quality with high efficiency. Its textured, thermally-optimized chassis enhances performance and durability all within a compact design built for the rack.

Ready to Rack

Designed specifically for Amp Multi, the 2U Rack Mount streamlines installations by reducing wasted space, maximizing airflow, and keeping cable management clean.

Built to Breathe

The Rack Mount creates space above and below each unit to support airflow in a clean, 2U configuration.

Streamlined Installation

With its flat back design, Amp Multi slides easily onto the Rack Mount. Installation is satisfyingly simple.

Space-Saving Design

Amp Multi eliminates the need for vent panels between rack units and reduces the number of screws required for installation—saving time, rack space, and hardware.

Looks Right at Home

Whether on a shelf, credenza, or mounted to the wall, Amp Multi’s compact design and refined finish make it an elegant addition to any space. It looks just as polished in plain sight as it does tucked into a rack.

Works with Your Devices

Partner integrations offer seamless control of your Sonos system alongside all your compatible smart home devices.

Responsible by Design

From major technological innovations to thoughtful details, Amp Multi is engineered with sustainability at every level.

Recycled Plastics

Amp Multi features 47% recycled plastic—helping reduce waste and give materials a second life.

Energy Eefficient

GaN technology helps Amp Multi consume less than 5.5W at idle to reduce heat and improve reliability, while software enhancements further reduce energy use during playback and standby.

Eco Packaging

The exterior and interior packaging is 100% recyclable and crafted using paper certified by the Forest Stewardship Council®.
