Sonos Amp Multi: High-Performance 8-Channel Multizone Amplifier
Sonos Amp Multi: High-Performance 8-Channel Multizone Amplifier
SKU:
The Sonos Amp Multi is a professional-grade, multizone amplifier engineered specifically for high-performance architectural audio installations. Redefining the capabilities of a compact 8-channel amplifier, the Amp Multi utilises advanced Gallium Nitride (GaN) technology and Post-Filter Feedback (PFFB) to deliver exceptional audio clarity, high power efficiency, and flexible system design in a streamlined 2U rack-mountable form factor.
Advanced Multizone Flexibility and GaN Efficiency
The Amp Multi provides unparalleled versatility for professional system integrators, featuring 8 amplified outputs that are each independently configurable for stereo or mono operation. This allows for up to four distinct audio zones, with each output assignable to any zone to meet bespoke system requirements. The integration of GaN technology is a major innovation, providing over 95% power efficiency. This high efficiency significantly reduces heat generation, allowing the unit to use fanless passive convection cooling. This results in a silent operation, reduced energy consumption, and a significant decrease in dust build-up within the equipment rack.
Audio performance is further refined by PFFB technology, which ensures exceptional clarity and reduced distortion, matching the sonic performance of high-end analogue devices while maintaining the lightweight efficiency of modern digital Class D designs. The Amp Multi delivers a robust 125W per channel at 8 Ohms with all channels driven, providing plenty of power for high-quality architectural speakers.
Professional Tools and Intuitive Configuration
For precision tuning, the Amp Multi features ProTune, a comprehensive manual control suite accessible via the Sonos app. This allows installers to optimise the sound for any low-impedance passive speakers using a 10-band parametric EQ, adjustable gain, and delay offsets. When used with Sonos Architectural speakers, the Optimise Sonos Speakers feature unlocks custom DSP and EQ tuning, allowing the unit to power up to three pairs of speakers per output (24 speakers total) while maintaining stable operation.
Configuration is streamlined through intelligent indicators and seamless cues. An audible chirp identifies each unit in the app for quick setup, while real-time LED status lights on both the front and rear of the chassis provide immediate feedback on device and output status. Connectivity is comprehensive and modern, supporting wired Ethernet or WiFi 6, and allowing for up to four audio sources to be streamed simultaneously via Apple AirPlay 2, Spotify Connect, or the Sonos app.
