FAQ

What is the difference between Amp and Connect:Amp?
Amp is more powerful than Connect:Amp, supporting 125 Watts per channel versus 55 Watts per channel. Amp also features an HDMI ARC input for TV integration, allows control with Apple AirPlay 2, and supports Trueplay when powering Sonos Architectural by Sonance. Both Amp and Connect:Amp have RCA line-in options.
Will a single Amp power more than two passive speakers?
Amp can power two pairs of 8-ohm nominal passive speakers when wired in parallel. Amp can power three pairs of Sonos Architectural by Sonance wired in parallel.
Will Amp power a pair of 6-ohm speakers and a pair of 8-ohm speakers?
No. All speakers must have the same impedance rating and be wired in parallel.
Can a single Amp act as two zones?
No. Each Amp acts as one zone, meaning all speakers wired to a single Amp will play the same content at the same volume.
Can I connect my TV to Amp and wire four speakers, two front and two rear, if all are 8 ohms?
This setup requires two Amps, one to integrate the TV and power the front speakers and another to power the rear speakers.
Can I use streaming services with Amp?
Yes. You have access to dozens of streaming services through the Sonos app. You can also control your system directly from selected partner apps, including Spotify, or by using Apple AirPlay 2 with your iOS device.
How do I use my streaming service with Amp?
Streaming services are set up through the Sonos app. You can also use Apple AirPlay 2 on an iOS device or stream directly from certain music services, such as Spotify.
Can I connect my computer to Amp through HDMI and control volume and functions through the computer?
If your computer outputs audio through an HDMI ARC connection, you can use it to control Amp. Additionally, the Sonos HDMI Adapter (sold separately) allows you to connect a computer with an optical SPDIF output to Amp.
What is the damping factor on Amp?
The damping factor is approximately 400 with an 8-ohm speaker.
Do I need to use the banana plugs or can I do a straight wire connection?
For the best sound and most reliable performance, we recommend using banana plugs. Amp comes with custom-designed banana plugs and is designed to work with any standard banana plug. Amp can also accommodate a straight wire connection with 10 to 18 AWG wire.
Can I connect my CD player to Amp and play CDs on my Sonos speakers?
Yes. You can connect your CD player to Amp using the analogue input. Select Line-in from the source menu in the Sonos app to begin listening.
If I connect a pair of outdoor speakers and a pair of indoor speakers to the same Amp, will all speakers need to play at the same time?
Yes. Amp is a single-zone product, which means all connected speakers will play the same content at the same volume.
Can Amp connect to a multi-channel AV receiver?
No. Amp only has speaker outputs. It does not have any analogue or digital output for connecting to an AVR.
Is the 125 W/channel a peak rating or rms/continuous?
Amp provides 125 W continuous average power sine wave, into an 8-ohm load, both channels driven.
How do the new processor and increased memory affect the product experience?
Currently there are no feature differences between Sonos One Gen 2 and the original version. The original Sonos One will continue to support all its current features, and more, in the future. Over time, however, the increased memory, Bluetooth Low Energy, and processing power may allow us to bring new product experiences to the Gen 2 version that the original will not be able to support. That said, we have no specific Gen 2-only features planned at this time.
Will Sonos One Gen 2 work in stereo pair and as surrounds with the original Sonos One?
Yes, the Gen 2 works seamlessly with the original Sonos One as a stereo pair or home cinema surrounds.
How does Sonos One Gen 2 use Bluetooth Low Energy?
Bluetooth Low Energy (BLE) was first introduced with Sonos Beam, and now we are bringing it to Sonos One Gen 2. Just like with Beam, BLE can be used to communicate temporarily with your phone or tablet to simplify the first-time setup process. BLE does not support audio streaming. Once setup is done, Sonos One Gen 2 streams and updates via your WiFi just like the original Sonos One.
How can I tell which version I have?
Sonos One Gen 2 is marked as “Gen 2” on the product label underneath the speaker. The original Sonos One only has “One” on the product label.

Reviews

Can't I just use my personal music streaming subscription?
You’ll still have to pay licensing fees to use music in your business. Additionally, if you want to get rid of the ads that interrupt the music, you’ll need to pay for a premium subscription on most services. It’s usually more cost effective to subscribe to a music streaming service for business use.
Why do I need a commercial music streaming service?
Composers, musicians, and artists deserve fair compensation, especially when their music offers extra value to your business. As a business owner, you’re legally responsible for paying license fees for music you play in your venue.
What is considered a public performance?
The Copyright Law of the United States defines a public performance of music as, “Music performed in a place open to the public or at any place where a substantial number of persons outside of a normal circle of a family and its social acquaintances is gathered.”
What are Performance Rights Organizations?
BMI, ASCAP, and SESAC are known as the Performance Rights Organizations (PROs) that represent songwriters and music publishers in the United States. If you play music licensed by one of these organizations and don’t have a license from them, you can potentially be held liable for copyright infringement, which can result in thousands of dollars of liability as well as costly legal fees.
