• 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 125W per channel into 8Ohm, Amp Multi powers high-performance passive speakers up to four stereo zones; This means four times the coverage compared to Amp, with consistent output even under complex loads
• Innovation from the inside and out; Advanced GaN technology, Class D amplification, and post-filter feedback (PFFB) deliver exceptional audio quality with high efficiency; All this power is housed in a thermally optimized chassis that enhances performance and durability
• Smart outputs; Configure multiple zones with assignable outputs and real-time LED feedback; Amp Multi detects when a speaker is connected and displays clear status indicators to simplify setup and troubleshooting
• Manually tune each output; With ProTune, you can optimize the sound for the placement and room acoustics of any low-impedance passive speakers; This feature offers a comprehensive set of manual controls, including a 10-band parametric EQ and adjustable gain and delay offsets
• 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
• 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
• Efficient Class D amplification; Class D technology delivers high power with maximum efficiency, reducing energy consumption and minimizing heat buildup; The result is a more reliable, sustainable amplifier that performs consistently across demanding installations
• Seamless setup; An audible chirp identifies each unit in the Sonos app, no PIN required; Front and rear LEDs indicate setup mode for a faster, more intuitive configuration
• Intelligent indicators; Front and rear LEDs deliver clear status updates and real-time feedback during setup and troubleshooting; Outputs automatically detect connected speakers, while an ambient light sensor adapts LED brightness to the environment, enabling quick, accurate diagnostics in any space
