Sonos just announced their all new Sonos Amp Multi; a one-of-a-kind multi-channel streaming amplifier designed to make complex residential audio installations simpler, more flexible, and more scalable. Developed specifically for large-scale projects, the Amp Multi extends the Sonos experience into larger, more developed home and commercial installations while preserving the quality and simplicity the brand is known for.
What is the Sonos Amp Multi?
The Sonos Amp Multi is a high-density, rack-mountable audio engine designed to deliver eight channels of professional-grade sound from a single unit. Where the original Sonos Amp transformed the way we approached single-room audio, the Amp Multi elevates Sonos into a true whole-home and commercial audio platform. It is no longer about adding sound room by room, but about building a complete, centralized audio ecosystem.
By consolidating amplification into a dedicated equipment rack, the Amp Multi allows us to power four independent zones from one component. A kitchen, a terrace, a living room, and a dining area can all operate independently, each with its own ambiance, volume, and musical identity, while remaining seamlessly accessible through the Sonos app. The user experience remains familiar and intuitive; what changes is the scale, the reliability, and the architectural elegance behind the scenes.
Technical Evolution
What truly differentiates the Amp Multi is its shift from consumer electronics to industrial-grade engineering. Every design decision reflects the realities of professional installation: heat management, power density, long-term stability, and serviceability.
Gallium Nitride (GaN) Technology
At the heart of the Amp Multi lies a Gallium Nitride power architecture. GaN technology allows Sonos to achieve impressive power density while maintaining exceptional efficiency. Each channel delivers up to 125 watts without the need for active cooling fans, a crucial factor for rack installations where silence and thermal stability are non-negotiable. The result is an amplifier that runs cooler, operates more efficiently, and maintains absolute reliability even in tightly packed technical spaces.
ProTune™ & PFFB
With ProTune, Sonos introduces an entirely new dimension to its ecosystem. For the first time, we can precisely tune architectural speakers using a 10-band equalizer. This allows the adaptation of each zone to its acoustic environment, correcting room resonances, optimizing tonal balance, and ensuring consistency across different spaces.
When paired with Post-Filter Feedback (PFFB), the system actively monitors and stabilizes the amplifier’s output. Even at high volume levels, sound remains controlled, detailed, and free of distortion.
2U Rack-Ready Design
The physical format of the Amp Multi is as intentional as its internal architecture. Its 64,5mm x 436,8mm x 265,2mm chassis is engineered specifically for professional racks, like the custom 2U rack made by Sonos, allowing cleaner installations, better airflow, and efficient cable management. The chaotic “cable spaghetti” disappears, replaced by structured, accessible, and service-friendly layouts. Space is saved, organization is improved, and long-term reliability is enhanced.
Engineering for Reliability
The Amp Multi incorporates advanced thermal monitoring, short-circuit protection, and continuous performance management. Its software-driven architecture ensures that your installation evolves over time, benefiting from firmware updates that refine stability, add functionality, and optimize performance.
Who is the Sonos Amp Multi meant for?
For clients who value simplicity and seamless integration at the heart of their living environment, the Amp Multi is transformative. Centralized amplification means that living spaces remain free of visible electronics. Only discreet in-ceiling and in-wall speakers remain, blending seamlessly into your home interior. Technology fades into the background, and music becomes part of the space itself rather than an object within it.
In commercial settings such as boutiques, restaurants, and offices, stability is paramount. The Amp Multi delivers the reliability of professional rack systems while maintaining the simplicity of the Sonos platform. It is designed for continuous operation, capable of handling complex speaker configurations and sustained workloads that would overwhelm conventional consumer amplifiers. Staff can control the environment through the familiar Sonos interface, while the underlying infrastructure operates at a professional standard. It removes the traditional compromise between power and usability
