Connector panel

1. HDMI port: Connect your soundbar to your TV's HDMI eARC or ARC port with an HDMI cable (included). For optical connection, use a Sonos Optical Audio Adapter (sold separately) and an HDMI cable.

2. Bluetooth button: Pair a new device by turning on Bluetooth in your device's settings, pressing and holding the button (about 2 seconds) until you hear a tone and the status light blinks blue, then selecting Arc Ultra from your device's Bluetooth settings. The status light will show solid blue when connected.

3. Ethernet port: Use an Ethernet cable to connect to a router, computer, or network-attached storage (NAS) device (optional).

4. Microphone switch: Toggle to turn all product microphones on or off. When the switch is off (down), 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. Note: Insert the power cord firmly until it is flush with the speaker.

Placement

Recommendations for optimal placement of your Sonos Arc Ultra soundbar:

• Place Arc Ultra on a stable, horizontal surface. Do not place it vertically or on its side.
• Do not enclose Arc Ultra in a cabinet or in a corner.
• Ensure the controls are facing up.
• For best sound quality, place Arc Ultra in front of and below your TV, or mount it above your TV.
• If placing Arc Ultra below your TV, maintain at least 4 inches (10 cm) of space 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

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.

Setup steps:

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 using an Ethernet cable, connect that to Arc Ultra as well.
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 not, connect the HDMI cable to your TV's optical port using the Sonos Optical Audio Adapter (sold separately). Follow these steps for the adapter:
   1. Remove the protective cap from the optical adapter, then attach it to the HDMI cable.
   2. Connect the optical adapter to your TV's optical digital OUT port. Note: Ensure the optical adapter aligns correctly before plugging it in, as incorrect insertion 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 inches (10 cm) of space (minimum) between the mounted soundbar and your TV.
• Ensure the controls are facing up.
• Keep both ends of the soundbar at least 1 inch (2.5 cm) from a wall or other obstructions.

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

Contents:

• Sonos Arc Ultra Wall Mount bracket
• Positioning guide (do not discard; it may look like packing material)
• 2 knobs
• 6 wall anchors
• 6 screws

Wall material and pre-drill sizes:

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 inches (14 cm) between the top of the wall mount bracket and the TV. Mark the screw locations and remove the wall mount bracket.
2. If using the included wall anchors, use a 5/16 in / 8 mm drill bit to drill pilot holes and then insert the wall anchors. Do not use anchors if 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, ensuring 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 connecting cables to the TV at this time, ensure the HDMI cable is plugged 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. Ensure the touch controls are facing up and the soundbar is fully seated.
