Sonos Amp Multi

You can set up Amp Multi in an electronics rack or place it anywhere with enough airflow in a home.

Rack mounted

• Amp Multi can mount perfectly in any standard-size electronics rack with the Amp Multi Rack Mount (sold separately).
• Amp Multi is 1.5U height without the Amp Multi rack mount, 2U height with the rack mount, and full rack width.
• We recommend adding 1U of active cooling for every 3 Amp Multis in a rack. You can generally mount 2 Amp Multi in a rack on top of each other without the need for active cooling. Closely examine the rack, space, and ventilation, as you may want to add active cooling regardless. For more information on heat dissipation, review the spec sheet.

Outside of a rack

• Place horizontally on a stable, level surface.
• Leave at least 4 inches (101 mm) of space on all sides, including above Amp Multi, and ensure there's adequate airflow to the area.
• Don’t place anything on top of the Amp Multi, including but not limited to books, decorations, speakers, and other amps.

Use the Sonos app to configure Amp Multi.

• Put all 8 outputs from an Amp Multi in a single zone, or distribute them however you want across up to 4 zones.
• A system can contain a maximum 32 zones or products. If a system only contains Amp Multis, you could add 8 Amp Multis with 4 zones each, 32 Amp Multis with 1 zone each, or a variation in between.
• When selecting outputs for a zone, selecting 2 outputs will automatically create a stereo pair. You can change that to Mono in Settings after you’ve completed setup.

You can set up zones with Amp Multi and additional products.

• Create large zones of passive speakers by combining outputs from up to 16 different Amp Multis.
• Add other eligible Sonos products to a zone after you’ve set up the Amp Multi by going to zone settings and editing the zone. Other products must also be set up on the system before they can be added to a zone.
• Connect a Sonos Sub 3, Sub 4, or Sub Mini by going to the zone settings and selecting Connect Sub, or connect a third-party sub using the subwoofer output. You can add a maximum of 1 sub per zone, and the zone can only contain Amp Multis.

To review the setup for an Amp Multi, go to the settings for a zone that contains at least 1 of its outputs, then select it from the list of products (Settings > Zone > Amp Multi). On the Amp Multi settings page, you can see how each output has been configured and enable or disable WiFi for the Amp Multi; WiFi is enabled by default.

Unused outputs

You don’t have to set up every output on Amp Multi right away. You can even hide them from Settings temporarily so they aren’t distracting or confusing.

To find hidden unused outputs, go to a zone that contains an output from that Amp Multi, then select it from the list of products (Settings > Zone > Amp Multi). You’ll see available outputs (i.e. unused outputs) at the bottom of the Amp Multi page, and can even add them to a new zone right there.

If you want to add unused outputs to an existing zone, go to System Settings, select the zone you want to add them to, and then select Edit Zone.

Setting up zones helps you fill large spaces with sound. A zone is a new semi-permanent configuration for multiple speakers throughout a system. Zones can be a single room, half of a room, or even multiple rooms in a home or building. Currently, these products can be added to a zone in the Sonos app: Amp Multi, Era 100, Era 100 Pro, Five, One, and One SL. You can also add a Sub to a zone that only contains Amp Multi.

Once a zone is created, all products added to it are controlled together as though they are a single item. This makes playing content to all the speakers in the same space easier, compared to giving them each a common name (e.g. Kitchen, Kitchen 2, Kitchen 3, etc.) and grouping them.

You can add a maximum of 16 products to a zone. Any number of outputs from a single amp counts as 1 product. A system can contain a maximum of 32 products or zones.

To ensure the best experience while using zones, we recommend setting up wired internet connections into each speaker. If using wireless connections (WiFi) instead, we recommend adding a maximum of 6 products per zone.

Use the output selector to temporarily group various zones and speakers together. When you ungroup, your zones will stay intact.

Set up a zone

Zones can be a single room, half of a room, or even multiple rooms.

1. Go to Settings .
2. Choose a compatible room, portable, or headphone (see the above list of compatible products).
3. Select Products, and then select + Set Up Zone to get started.

Speakers remain in a zone until you Edit Zone or Separate Zone in Settings .

Manage, edit, and separate your zones

After a zone is created, you can change the speakers in a zone or remove a zone altogether.

1. Go to Settings and select a zone.
2. Under Products, select either Edit Zone to add or remove speakers in the zone or Separate Zone to disconnect all speakers in the zone.

Identify speakers in a zone

If you lose track of which speakers are in your zone, you can check them by going to System Settings, selecting the zone, and reviewing the product list. In the app, speakers in a zone have a speaker icon next to them within Settings. You can press that icon to have it play a short sound and flash its LEDs so you can identify its physical location.

For advanced tuning needs, installers can use ProTune to optimize the sound for the placement and room acoustics of any low-impedance passive speakers connected to Amp Multi. It offers a comprehensive set of manual controls, including a 10-band parametric EQ and adjustable gain and delay offsets.

ProTune is an advanced tuning tool and should only be used by trained professionals. Sign in to protune.sonos.com with the account information for the system you want to modify.

If you’re using Sonos Architectural speakers, you should complete the Optimize Sonos Speakers flow using the Sonos app before tuning with ProTune.
