The Sonos Amp Multi delivers 8 x 125W of power across up to four zones, leveraging advanced GaN technology and post-filter feedback (PFFB) for greater efficiency, clarity, and control. With ProTune, installers can optimise the sound for any low-impedance passive speakers, tailoring performance to placement and room acoustics. ProTune offers a full suite of manual controls, including a 10-band parametric EQ plus adjustable gain and delay offsets, enabling truly bespoke audio experiences. Its innovative chassis design enhances thermal performance, while recessed connectors, status LEDs, and a streamlined 2U rack mount simplify setup and ensure reliable, fanless cooling.
