Sonos is back with new hardware, and it’s not a speaker or a soundbar. It’s something a bit more behind the scenes but no less important: a multi-channel streaming amplifier called the Amp Multi.

If you’re thinking, “Didn’t Sonos already have an amp?” — you’re right, that was the Sonos Amp. But this one is different. The Amp Multi is built with professional installers in mind, not everyday DIY users. It’s designed to handle bigger, more complex home audio setups that go beyond just a few rooms or a single open space. Think high-end smart homes with built-in speakers everywhere from the kitchen to the patio, and maybe even the garage.

“Sonos Amp is the most widely used two-channel streaming amplifier in residential installation because it’s powerful, dependable, and intuitive,” said Tom Conrad, CEO of Sonos. “Amp Multi takes that same philosophy and applies it to larger systems. It makes ambitious designs more efficient to build and install, and easier to live with.”

At the heart of the Amp Multi are eight channels, each pushing 125 watts. That’s enough to power up to 24 Sonos Architectural speakers, three per channel. It supports up to four independent audio zones, and any output can be assigned to any zone. So if someone decides to turn their gym into a guest bedroom (or vice versa), you don’t have to rewire the whole system, just reassign zones through the app.

And yes, multiple Amp Multi units can be connected for even bigger installs. That means integrators can scale things up room by room or floor by floor, depending on the needs of the home.

The Amp Multi isn’t just about power; it’s also about practicality. It fits neatly into a rack setup with a 1.5U chassis, and Sonos offers a 2U rack mount (sold separately) that helps with ventilation by creating breathing room above and below the unit.

The flat-back design and recessed connectors make it easy to stand the unit upright during installation. And speaking of setup, each Amp Multi emits a unique audio chirp when triggered in the Sonos app, so installers don’t have to guess which unit they’re configuring. No need to fumble with tiny PIN codes or labels in a crowded rack.

Sonos didn’t just beef up the channel count; they also rethought how the amp delivers power. The Amp Multi uses GaN (Gallium Nitride) power components and Class-D post-filter feedback, a combination that’s meant to improve power efficiency and keep things cool.

This also means there are no internal fans. Less noise. Fewer moving parts. Less chance of dust buildup. All things that make a big difference when the amp is expected to run quietly and reliably in the background for years.

The Amp Multi introduces a new tuning feature called ProTune, which is basically a toolbox of manual sound controls. With ProTune, integrators can adjust:

• 10-band parametric EQ
• Gain settings
• Delay offsets
• Width control (to tweak stereo image)

It’s a step up from the plug-and-play experience most Sonos users are used to. And it gives installers more flexibility to get the sound just right, especially in tricky spaces where speakers can’t be placed symmetrically or where acoustics are uneven.

For jobs using Sonos Architectural speakers, there’s also a built-in feature that automatically applies optimized DSP settings. So you can still get solid results without having to manually dial in every speaker from scratch.

“We created Amp Multi with integrators at the heart of every decision, drawing on their deep understanding of real-world installation challenges to design a product around how they actually work,” said Chris Heintzelman, VP, Product at Sonos. “The goal was to reduce friction at every stage of a project, from installation and setup to system tuning. This is about giving professionals more control while keeping the system approachable for the people who live with it every day.”

Let’s be clear: the Amp Multi isn’t designed for the average Sonos customer. It’s not something you’ll see on store shelves or order directly from the website. Instead, it’s being sold exclusively through Sonos installation partners, and it’s meant to be used in professionally installed systems.

If you’re someone who’s building or renovating a home and planning for built-in speakers in multiple rooms, this is the kind of gear your installer might recommend. But it’s probably not something you’d install on your own, or need to.

This is the first new piece of hardware we’ve seen from Sonos in over a year, and it’s clearly a different kind of release. After a bumpy couple of years, marked by a poorly received app update, some overheating speaker issues, and a canceled set-top box, Sonos seems to be pivoting, at least a little.

Instead of chasing flashy consumer gadgets with this release, the company is reinforcing its presence in the custom installation space. According to Sonos, Amp Multi was built in close collaboration with integrators, which makes sense given how tailored it is to their workflows.

And while there’s no official pricing yet, Sonos has confirmed the Amp Multi will roll out globally in the coming months through its pro installer network.

If you happen to be attending Integrated Systems Europe (ISE) 2026 in Barcelona, Sonos is showing off the Amp Multi in Hall 1, Booth 1E500, with demos happening every 15 minutes. It’s one of the more installer-focused products they’ve shown in a while, and could be a sign of what’s to come in the second half of the year, when Sonos says more hardware launches are on the way.
