To connect a phone to a Denon, put the specific Denon model into its Bluetooth input or pairing mode, then select its name in the phone’s Bluetooth settings. The button sequence and supported Bluetooth functions vary by model, so use the instructions for your exact unit rather than assuming one Denon procedure applies to all products.

Before pairing, identify your Denon model

Find the model number on the unit or in its documentation, then consult that model’s Denon owner’s manual. Denon receivers and soundbars do not all use the same pairing controls or display prompts. Bluetooth can also serve different purposes: some models receive music from a phone, while others separately support listening through Bluetooth headphones. Check the manual to confirm that your model supports the function you want.

Connect a phone to Denon Bluetooth

  1. Select Bluetooth on the Denon. The AVR-S570BT switches to its Bluetooth input when you press Bluetooth. On the DHT-S218 soundbar, turn it on and select the Bluetooth input. The AVR-X510BT enters pairing mode automatically the first time Bluetooth is selected.
  2. Enter pairing mode if needed. For the AVR-X510BT, hold Bluetooth for about three seconds or choose Pairing Mode from its options menu when pairing another device. For the DHT-S218, hold its Bluetooth control for three seconds to pair an additional device; its status LED blinks blue while it is in pairing mode. Follow the instructions for your own model if it differs.
  3. Open Bluetooth settings on your phone. Turn on Bluetooth and look for the Denon name in the available-device list. Select it. For the AVR-S570BT, Denon recommends pairing with the source about 1 meter (3.3 feet) from the unit while the pairing screen is displayed.
  4. Confirm pairing if prompted. If the phone and Denon display matching numbers, confirm that they match. The AVR-X510BT manual says to enter 0000 if the source device asks for a password; this is a model-specific instruction, not a universal Denon PIN.
  5. Play audio from the phone. Start a track or other audio in an app on the source device. The Denon should play it while its Bluetooth input is selected.

On the AVR-S570BT, a device that has paired successfully does not need to be paired again; selecting Bluetooth later reconnects the last paired device. The AVR-X2700H manual describes reconnecting by selecting the Denon in the source device’s Bluetooth list. To switch Bluetooth sources on that model, disconnect the currently connected device first.

Standard Bluetooth and LE Audio on the DHT-S218

The DHT-S218 offers standard Bluetooth and a separate LE Audio entry. These instructions apply to this soundbar, not to Denon products generally.

  • For standard Bluetooth, select Denon DHT-S218 in the source device’s Bluetooth list.
  • For LE Audio, select LE-Denon DHT-S218 if the source supports it. Denon’s DHT-S218 manual says iPhone does not support Bluetooth LE Audio; it specifies Android 13 or later for an Android smartphone using LE Audio.
  • A new Bluetooth device cannot be paired while an LE Audio connection is active on the DHT-S218. Disconnect LE Audio before pairing another device. If the source cannot connect to LE Audio, Denon recommends trying the standard Denon DHT-S218 entry.

Fix common Denon Bluetooth connection problems

The Denon does not appear in the phone’s device list

  • Check that the Denon is in pairing mode, not merely powered on or set to another input.
  • Keep the phone close to the unit while pairing.
  • Check whether another source is already connected. The DHT-S218 supports only one connected Bluetooth device at a time.
  • For model-specific controls or prompts, follow the owner’s manual for your Denon.

The phone says it is paired, but there is no sound

  • Make sure the Denon’s Bluetooth input is selected.
  • Start playback on the phone, then check volume and mute on both the phone and the Denon.
  • If the DHT-S218 is connected to another Bluetooth device, disconnect that device before trying the phone.

The connection drops or audio stutters

For the DHT-S218, Denon recommends bringing the devices closer and reducing obstacles or nearby sources of interference. If the connection remains unreliable, restart the source device, clear its old pairing information for the soundbar, and pair again. These are DHT-S218 manual instructions; owners of other models should use their model’s troubleshooting guidance.
