What is the warranty length for Amp Multi?

What is the damping factor of Amp Multi?
The damping factor is approximately 437 when paired with an 8-ohm speaker.

What if I’m in a noisy environment and my device can’t hear the setup chirp?
If the chirp is not detected, you can enter the PIN printed on the back of the unit directly in the Sonos app.

How much clearance does Amp Multi need for airflow if it’s not rack-mounted?
We recommend allowing at least four inches (10 centimetres) of space on the top and sides for proper ventilation.

Does Amp Multi support Trueplay?
No, Amp Multi introduces ProTune—a manual tuning feature that lets you fine-tune the sound for any low-impedance passive speaker and room. When used with Sonos Architectural speakers, enabling Optimise Sonos Speakers applies custom tuning and DSP tailored to their unique acoustic design.

Why is Amp Multi 1.5U in height, and how does that fit in a rack?
Amp Multi shares the same 1.5U height as Sonos Amp, ensuring consistency when mixing device types. The Rack Mount (sold separately) adds an extra 0.25U of space above and below the unit—for a total height of 2U—for optimal airflow and easier access without wasting rack space.

How do I assign the subwoofer output to a specific zone?
In the Sonos app, go to Zone Settings, select Connect Sub, and follow the instructions to assign the subwoofer output to the desired zone.

How many subwoofers can Amp Multi support?
Amp Multi supports Sonos Sub 4, Sub (Gen 3), and Sub Mini. You can assign one Sonos Sub per zone, up to four total. The subwoofer output port supports a powered third-party sub, which can be freely assigned to any zone in the app.

Why doesn’t Amp Multi include HDMI like Sonos Amp?
Amp Multi is purpose-built for bespoke, distributed audio applications. If you need HDMI connectivity for TV or home theatre setups, Sonos Amp or a Sonos soundbar is the best fit, with both offering the ability to work seamlessly alongside Amp Multi in the same system.

Is Bluetooth® supported?
No, Amp Multi does not include Bluetooth connectivity.
