Listening to music wirelessly with 2 speakers (Stereo Pair function)

To use the Stereo Pair function, 2 ULT TOWER 10 speakers are required. By connecting 2 speakers via a BLUETOOTH connection, you can enjoy more powerful sound.

2 speakers connected via a BLUETOOTH connection play sounds in stereo, where 1 speaker plays the sound on the right channel (right side) and the other plays the sound on the left channel (left side).


Before operating the speaker, make sure of the following:

  • Update the pre-installed software to the latest version on each and every speaker to connect for the function.

    (For details about the update procedure, see Updating the pre-installed software.)

  • When setting up the speakers for the Stereo Pair function, make sure that the 2 speakers to connect for the function are located within 1 m (3.2 ft) from each other. Stop music playback if it is in progress.

  • When playing music, make sure that all of the devices to connect for the function are located within 30 m (98.4 ft) in your line of sight.

    Maximum communication range may shorten under the following conditions.

    • There is an obstacle such as a person, metal, or wall between the speaker and BLUETOOTH device.
    • A wireless LAN device is in use near the speaker.
    • A microwave oven is in use near the speaker.
    • A device that generates electromagnetic radiation is in use near the speaker.
  1. Use “Sony | Music Center” to set up the speaker for the Stereo Pair function.

To terminate the Stereo Pair function

Use “Sony | Music Center.”

Hint

  • Use of the Stereo Pair function automatically switches the codec to SBC.

  • Turning off the speakers does not turn off the Stereo Pair function. When one of the speakers is turned back on, it attempts to establish a connection for the Stereo Pair function. To use the Stereo Pair function, turn on the other speaker within 1 minute. When the BLUETOOTH standby function remains active on both of the speakers, however, turning on either of the speakers automatically turns on the other and establish a connection for the Stereo Pair function between the speakers.

Note

  • While the Stereo Pair function is in use, audio from the following devices connected to the speaker will not be output.

    • The USB device connected to the PLAY/CHARGE OUTPUT port (USB)

    • The device connected to the AUDIO IN jack by an audio cable

    • The TV connected to the OPTICAL IN connector

  • While the speaker is in OPTICAL IN, AUDIO IN, or USB mode, you can set it up for the Stereo Pair function with “Sony | Music Center” as well. Upon completion of the setup, however, the speaker is automatically placed into BLUETOOTH mode.

  • Deactivating the Stereo Pair function gives no effect on the established BLUETOOTH connection and the speaker remains in BLUETOOTH mode. To place the speaker into OPTICAL IN, AUDIO IN, or USB mode, a respective tap operation on the speaker is required.

  • To avoid any sudden loud sound output from the speaker, turn down the volume of the speaker and a BLUETOOTH device or stop the playback on the BLUETOOTH device before establishing a connection with the BLUETOOTH device.
