Sonos Amp Multi – Multizone Streaming Amplifier

More zones. Greater flexibility.

Amp Multi delivers 8 x 125W of power across up to four zones, leveraging advanced GaN technology and post-filter feedback (PFFB) for greater efficiency, clarity, and control.

With ProTune, installers can optimize the sound for any low-impedance passive speakers, tailoring performance to placement and room acoustics. ProTune offers a full suite of manual controls, including a 10-band parametric EQ plus adjustable gain and delay offsets, enabling truly bespoke audio experiences.

Its innovative chassis design enhances thermal performance, while recessed connectors, status LEDs, and a streamlined 2U rack mount simplify setup and ensure reliable, fanless cooling.

Multi-zone capability
Power up to four independent zones with eight assignable outputs. Each output can be freely configured to suit room layouts, speaker counts, and wiring needs.

Powerful and flexible
With 125 watts per channel into 8 ohms, Amp Multi powers high-performance passive speakers across up to four stereo zones. This means four times the coverage compared to Amp, with consistent output even under complex loads.

Easy app control
Manage zones, sources, and output assignments all within the Sonos app. Stream up to four audio sources simultaneously and control each zone independently, providing the familiar, intuitive experience you know and love from Sonos.

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.

Ready to rack
The optional 2U Rack Mount streamlines installations by minimizing wasted space, optimizing airflow, and supporting clean cable management. Secure Amp Multi with just eight screws — it's all satisfyingly simple.

Efficient Class D amplification
Class D technology delivers high power with maximum efficiency, reducing energy consumption and minimizing heat buildup. The result is an amplifier that performs consistently across demanding installations.

Precisely tuned for each space
Each output can be fine-tuned for the unique acoustics and character of the room, delivering a tailored sound experience for any style of music, movie, or content.

Energy efficient
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.

Responsible by design
As part of our commitment to sustainability, Amp Multi is made with recycled materials, energy-efficient technology, and a serviceable construction designed for long-term use.

Power more speakers
Pair Amp Multi with up to three Sonos Architectural speakers per output. This means more coverage without the need for extra amps. Built-in tuning optimizes the sound for each room, while limiter controls help protect your system for lasting performance.

Built-in overdrive protection
Advanced overdrive protection safeguards the system from overheating or failure, ensuring reliable performance even when powering up to three passive Sonos speakers per channel.

Bass options for every zone
Connect one Sonos subwoofer per zone for deeper, more powerful bass. Supports Sub 4, Sub (Gen 3), and Sub Mini, with the option to connect a third-party active subwoofer.

Flexible network connectivity
Connect using wired Ethernet or WiFi 6 with auto-optimizing antennas for a strong, reliable connection. Multiple network options provide greater flexibility in setup and ensure stable performance in any environment.

More ways to play
RCA and USB-C inputs let you connect additional audio sources with ease, offering clients more ways to listen to all the content they love. USB-C requires the Sonos Line In Adapter.

Ready to rack
The 2U Rack Mount is designed to house more amplifiers in less space. That means a cleaner look, a smaller footprint, and a system that blends neatly into your home.

Creating products that last
Amp Multi is engineered for long-term reliability, with an architecture that uses screws instead of adhesives for easier service access. This design extends the product’s lifespan and helps minimize its environmental impact over time. Amp Multi comes with a 3-year warranty, giving you peace of mind and reliable coverage.
