Description
Sonos Amp Multi
Sonos Amp Multi is precision-built for ultimate flexibility, delivering premium multi-zone audio from a single, rack-friendly unit. Designed to power up to four independent zones, it pairs with virtually any low-impedance passive speakers, including Sonos Architectural models, and brings reliable, high-performance sound to every room in your home.
Four Zones, Endless Possibilities
Stream up to four different audio sources simultaneously using Apple AirPlay 2, Spotify Connect, or the Sonos app for complete control. Connect external sources such as a turntable via RCA or USB-C (with Sonos Line-In Adapter) and route that audio to any zone. Each zone features independent music selection and volume control, giving you total flexibility across your home.
Powerful, High-Efficiency Amplification
Delivering 125 watts per channel at 8 ohms (all channels driven), Sonos Amp Multi uses advanced Class D amplification with GaN and Post Filter Feedback (PFFB) technology for exceptional clarity, control, and stability. With a damping factor greater than 400 and total harmonic distortion as low as 0.005%, it ensures clean, detailed sound with impressive channel separation and a 114dB signal-to-noise ratio.
Each of the eight amplified outputs can be independently configured for stereo or mono operation, allowing tailored system design for any installation scenario.
Advanced Audio Tuning & DSP
Sonos Amp Multi includes ProTune, a powerful per-channel 10-band parametric EQ with adjustable gain (±15dB), Q, and frequency control. High-shelf, low-shelf, and bell filters are supported, along with gain trim (-15 to +5 dB), delay (0–50ms), and high-pass filtering (15–100Hz).
When paired with Sonos Architectural speakers, the system automatically recognises the speakers and applies custom DSP tuning for more robust sound, improved frequency balance, and optimised system stability.
Innovative, Rack-Friendly Design
The compact chassis is engineered for streamlined installation and efficient cooling, even when stacked in a rack. Available in a refined matte black finish, Amp Multi looks equally at home on a shelf, inside a cabinet, wall-mounted, or integrated into a professional rack system.

Comprehensive Connectivity
Sonos Amp Multi supports both wired and wireless networking. It includes a 100BaseTX Ethernet RJ45 port and WiFi 6 compatibility (802.11a/b/g/n/ac/ax 2.4GHz / 5GHz). Power is handled by an auto-switching 100–240V AC universal input.
Connectivity includes:
- 8 amplified speaker outputs (independently configurable)
- 2 x RCA analogue inputs (-10dB, stereo into one zone)
- USB-C analogue input (44.1kHz / 16-bit stereo, requires Sonos Line-In Adapter)
- 1 x RCA subwoofer output (-10dB, configurable per zone)
- 1 x Sonos Sub per zone support
Direct streaming formats include Apple AirPlay 2, Spotify Direct Control, and more, all managed through the Sonos app. A quad-core CPU (4xA55 1.9GHz) ensures responsive performance.
Energy Efficient & Built to Last
Engineered for efficiency and longevity, Sonos Amp Multi consumes less than 5.4W when idle (WiFi disabled) and is designed to be serviceable, extending product lifespan while reducing environmental impact.
