DETAILS

Flexible 4-zone Sonos system delivering high-fidelity audio indoors and outdoors for homes or commercial spaces.

The Sonos Amp Multi Indoor & Outdoor Speaker System is a professional-grade, multi-zone audio solution designed to deliver seamless, high-quality sound across both indoor and outdoor areas.

This complete package includes the Sonos Amp Multi 4-Zone / 8-Channel Smart Streaming Amplifier, six Sonos In-Ceiling Speakers, and two Sonos Outdoor Speakers by Sonance, providing a flexible, scalable system suitable for homes, offices, hospitality venues, and commercial environments.

Whether you’re looking to install a sophisticated multi-room system in a residential lounge, kitchen, and patio, or providing background and entertainment audio in a bar, restaurant, hotel terrace, or corporate space, this system adapts effortlessly to your environment.

At the heart of the system is the Sonos Amp Multi, a high-performance 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, precision, and control across a wide range of speaker loads. Its fanless, thermally optimised design ensures silent operation and long-term reliability, ideal for rack-mounted or discreet installations in both home and commercial settings.

True Multi-Zone Control – Indoors and Outdoors

Each of the eight amplifier outputs can be freely assigned to any zone, allowing installers to create fully customised layouts. In this package, the system can be configured for three indoor zones using the ceiling speakers and a dedicated outdoor garden or patio zone using the Sonos Outdoor Speakers.

Stream up to four audio sources simultaneously via the Sonos app, Apple AirPlay 2, or Spotify Connect, providing independent or synchronised content for each zone. This makes the system perfect for multi-room residential setups or commercial environments where multiple areas require separate music, announcements, or ambiance.

Optimised for Sonos Architectural and Outdoor Speakers

The Sonos In-Ceiling Speakers and Sonos Outdoor Speakers by Sonance are designed to integrate seamlessly with the Sonos Amp Multi, enabling automatic DSP tuning for each speaker and zone. ProTune allows installers to fine-tune 10-band parametric EQ, gain, delay, and high-pass filtering on a per-channel basis, ensuring optimal audio performance in any environment.

This system provides true multi-zone audio for commercial spaces, while still delivering the refined, immersive sound Sonos is renowned for in homes.

Stylish Indoor Design & Durable Outdoor Performance

The Sonos In-Ceiling Speakers provide a discreet, design-led solution for indoor areas. Paintable magnetic grilles allow the speakers to blend seamlessly with ceilings in residential lounges, kitchens, or commercial dining areas.

The Sonos Outdoor Speakers deliver rich, clear audio in external environments. Featuring a 6.5" woofer and precision tweeter, they maintain detail and power even in open-air spaces. Their IP66 weatherproof rating ensures resilience against rain, UV exposure, heat, humidity, salt spray, and freezing temperatures, making them ideal for gardens, terraces, hotel patios, or poolside zones.

Professional Installation, Simplified

Amp Multi is purpose-built for professional installation, featuring recessed rear connections, intelligent status LEDs, and an optional 2U rack mount (sold separately) for optimal airflow and efficient use of space.

The Sonos Outdoor Speakers include robust, adjustable brackets and hidden cabling for flexible mounting under eaves, on walls, posts, or corners. Standard 2-core speaker cable is used throughout, with outdoor-rated cable recommended for external runs.

Setup is quick and intuitive with the Sonos app, featuring an audible identification chirp for each unit — no PIN codes required. This system delivers a future-proof, multi-zone audio solution suitable for both home and commercial installations.
