Note: the microphone switch located on the connector panel (back) must be turned on to use voice services.

Status light: Displays the state of the product in various situations, such as connecting to WiFi or Bluetooth, and signals errors. Gives feedback when buttons on the product are pressed and when a command is sent from a remote.

Connector panel

1. HDMI port (ARC or eARC): Connect your soundbar to your TV's HDMI eARC or ARC port with an HDMI cable (included).

Optical: Connect your soundbar to your TV's optical port with a Sonos Optical Audio Adapter (sold separately) and an HDMI cable (included).

2. Bluetooth button : Pair a new device: 1. Turn on Bluetooth in your device's settings. 2. Press and hold until (about 2 seconds) you hear a tone and the status light blinks blue. 3. Go to the device's Bluetooth settings and select Arc Ultra from the list. When your Arc Ultra successfully connects to Bluetooth, the status light will show solid blue.

3. Ethernet: 10/100 port for hardwiring to your router.

4. Microphone switch: Toggle to turn all product microphones on or off. When the switch is off (down), the microphones are disabled so microphone-enabled features like Trueplay quick tuning and voice services are unavailable. When the switch is on (up), microphone-enabled features are available. Note: To use voice services, both the microphone switch and the voice services indicator light must be on.

5. AC power (mains) input: Use only the included power cable (using a third-party power cord will void your warranty). Note: Insert the power cord firmly until it is flush with the speaker.

Placement

Here are some recommendations to get the most out of your Sonos Arc Ultra soundbar:

• Place Arc Ultra on a stable, horizontal surface. Don't place it vertically or on its side.
• Don't enclose Arc Ultra in a cabinet or in a corner.
• Make sure the controls are facing up.
• For best sound quality, place Arc Ultra in front of and below your TV. Alternatively, you can mount it above your TV.
• If placing Arc Ultra below your TV, keep 4 in (10 cm) of space (minimum) between the top of the soundbar and the bottom of your TV.
• Position the front of Arc Ultra as close to the edge as possible.

Connect the cables

When your soundbar is securely where you want it, use the included cables to set up your Arc Ultra.

Before you start:

• Disconnect existing home theater or surround sound equipment from your TV.
• Connect any external devices, like a streaming box or DVD player, directly to your TV.
• Turn your TV on.

1. Connect the power cable to Arc Ultra and plug it in to power. Note: Use only the included power cable (using a third-party power cord will void your warranty).

2. Connect the HDMI cable (included) to Arc Ultra. If you're using an Ethernet cable, connect that to Arc Ultra too.

3. Connect the other end of the HDMI cable to your TV:

• If your TV has an HDMI ARC or eARC port, connect the HDMI cable to it.
• If your TV doesn't have an HDMI ARC or eARC port, connect the HDMI cable to your TV's optical port with the Sonos Optical Audio Adapter (sold separately):
  1. Remove the protective cap from the optical adapter, then attach the optical adapter to the HDMI cable.
  2. Connect the optical adapter to your TV's optical digital OUT port.
  Note: Make sure the optical adapter aligns correctly into the port before securely plugging it in. Inserting the adapter incorrectly may damage the adapter.

Wall mount

Use the Sonos Arc Ultra Wall Mount (sold separately) to mount Arc Ultra to the wall below (recommended) or above your TV. Sonos recommends:

• Keep 4 in (10 cm) of space (minimum) between the mounted soundbar and your TV.
• Make sure the controls are facing up.
• Keep both ends of the soundbar at least 1 in (2.5 cm) from a wall or other obstructions.

Note: Arc Ultra is also compatible with Sonos Arc Wall Mount.

Contents:

• Sonos Arc Ultra Wall Mount bracket
• Positioning guide (don't discard—it may look like packing material)
• 2 knobs
• 6 wall anchors
• 6 screws

Installation

1. Use the wall mount bracket to mark screw locations. Align the top edge with the bottom of your TV. There should be 5.5 in (14 cm) between the top of the wall mount bracket and the TV. Mark the screw locations and remove the wall mount bracket for now.
2. If you're using the included wall anchors, use a 5/16 in / 8 mm drill bit to drill the pilot holes and then insert the wall anchors. Don't use the anchors if you're drilling into wood or plastic.
3. Position the wall mount bracket over the marked screw locations, using a level to confirm accuracy. Use a Phillips-head screwdriver or a power drill to screw the bracket to the wall, making sure the arrows in the center are pointing up.
4. Screw the 2 knobs (thumb screws) into the back of the soundbar until they are fully tightened.
5. Connect the power and HDMI cables to the back of the soundbar. Note: If you're connecting the cables to the TV at this time, be sure to plug the HDMI cable into the HDMI ARC or eARC port on your TV.
6. Slide the soundbar down so the knobs fit into the slots on the wall bracket. Make sure the touch controls are facing up and the soundbar is fully seated.
