DETAILS

Professional multi-zone Sonos system delivering high-quality distributed audio for homes or commercial spaces.

The Sonos Amp Multi 4-Zone Ceiling Speaker System is a powerful, scalable audio solution designed to provide seamless, high-performance sound across multiple indoor zones.

This complete package includes the Sonos Amp Multi 4-Zone / 8-Channel Smart Streaming Amplifier and eight Sonos In-Ceiling Speakers, making it an ideal system for both residential multi-room audio and commercial background music installations.

Whether installed throughout a modern home with audio in the lounge, kitchen, dining room and bedrooms, or across a restaurant, bar, retail space, office, or place of worship, this system delivers consistent, high-quality sound with intuitive control and professional reliability.

At the heart of the system is the Sonos Amp Multi, a high-performance multi-zone streaming amplifier offering eight amplified channels at 125W per channel. Built around advanced GaN (Gallium Nitride) Class-D amplification with post-filter feedback (PFFB), Amp Multi delivers exceptional efficiency, low heat output, and precise speaker control — making it perfectly suited to continuous daily use in commercial environments as well as premium residential installations.

Its fanless, thermally optimised design ensures silent operation, while the compact 2U form factor allows for discreet rack mounting or cupboard installation.

True Multi-Zone Audio for Homes and Businesses

With eight independently configurable amplifier channels, this system can be set up as four separate audio zones, each capable of playing different content or perfectly synchronised audio throughout the building.

Using the Sonos app, Apple AirPlay 2, or Spotify Connect, users can stream up to four different audio sources simultaneously, making it ideal for:

Homes with independent room control
Restaurants with different dining areas
Bars with background music and feature zones
Offices with breakout areas and meeting rooms
Retail spaces requiring zoned background audio

This makes it a true “Sonos for business” solution, while retaining all the simplicity and user experience Sonos is known for in the home.

Optimised for Sonos Architectural Speakers

The included Sonos In-Ceiling Speakers are fully optimised for use with the Sonos Amp Multi, enabling automatic DSP tuning and advanced system control. Using ProTune, installers can apply 10-band parametric EQ, gain, delay and high-pass filtering per channel, ensuring optimal performance in every zone regardless of room size or acoustic conditions.

This allows the system to be precisely tailored for commercial ceiling heights, open-plan spaces, or acoustically challenging environments, while still delivering refined, immersive sound in residential settings.

Discreet Design with Powerful Performance

The Sonos In-Ceiling Speakers provide a clean, minimalist aesthetic with magnetic, paintable grilles, allowing them to blend seamlessly into any ceiling. This makes them ideal for both interior design-led homes and commercial spaces where visual impact must be kept minimal, such as restaurants, hotels and retail environments.

Despite their discreet appearance, each speaker delivers rich midrange, controlled bass and crisp high frequencies, providing evenly distributed sound coverage across large areas without the need for visible wall-mounted speakers.

Professional Installation Made Simple

The Sonos Amp Multi is designed with installers in mind, featuring recessed rear connections, intelligent status LEDs, and support for rack mounting (optional 2U rack kit sold separately). This makes it easy to integrate into professional AV racks or hidden installations.

Setup is fast and intuitive using the Sonos app, with each amplifier output identifiable via audible tone — eliminating complex manual configuration. Once installed, the system offers reliable long-term operation, making it ideal for commercial audio systems that need to run every day with minimal maintenance.
