The Sonos Amp Multi is a multi-channel streaming amplifier designed for complex residential audio installations and developed for and in collaboration with integrators.
Equipped with eight amplified outputs delivering 125W each and up to four configurable zones, the Sonos Amp Multi is designed as an upgraded of the Sonos Amp for larger systems.
Amp Multi combines Sonos’ streaming platform and intuitive control with an architecture built for professional workflows, says the company. Any output can be assigned to any zone, systems can scale by adding units as needed, and high speaker counts can be driven. Each output supports up to three Sonos Architectural speakers for a total of up to 24, enabling dense, efficient installations across multiple rooms or spaces.
At the hardware level, Amp Multi uses a highly efficient GaN power architecture paired with Class-D post-filter feedback. This design delivers clean, controlled sound while improving thermal efficiency across every zone, allowing the system to operate silently without fans and remain stable over long periods of use.
Amp Multi is designed to give integrators flexibility, control, and predictability across the entire lifecycle of a project. The scalable solution integrates seamlessly with third-party control systems.
Each unit emits a unique audible chirp, triggered from the Sonos app, removing the need for manual PIN entry and reducing time spent identifying hardware in the rack. The Sonos app also enables integrators to manage zones, sources, and outputs more efficiently.
Amp Multi also introduces ProTune, a manual sound optimization tool that gives integrators granular control of each output, including a 10-band parametric EQ, gain, width control ,and delay offset. These tools make it possible to fine-tune sound for challenging speaker placement and room geometry, while Optimize Sonos Speakers delivers detailed DSP profiles for Sonos Architectural speakers.
Built for modern racks, the 1.5U chassis paired with the dedicated 2U Rack Mount, sold separately, creates built-in ventilation space above and below each unit. This layout removes the need for additional vent panels and helps maintain clean cable management.
Amp Multi’s flat-back design and recessed connectors allow the unit to stand upright while the Rack Mount slides into place. The entire install process requires only eight screws.
The Sonos Amp Multi will be available globally through Sonos installation partners in the coming months. It will also be on display at ISE 2026, which takes place February 3-6, 2026 in Barcelona, Spain.
