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

To use the Stereo Pair function, 2 SRS-XB43 speakers are required. By connecting 2 speakers via BLUETOOTH connection, you can enjoy more powerful sound.

One speaker plays the sound on the right channel (right side), while the other speaker plays the sound on the left channel (left side) for stereo playback between the speakers.

For Apple iOS devices, the unit is compatible with iOS 10.0 or later. A BLUETOOTH connection is not available on the devices with iOS 9.x or earlier.

Note

  • Before establishing a connection between the speaker and a BLUETOOTH device, turn down the volume of the speaker and the device or stop music playback on the device to avoid any sudden loud sound output from the speaker.

  1. Place 2 speakers within 1 m (3.2 ft) each other, and then turn on both speakers.

    The(power) indicator lights up.

    The (BLUETOOTH) indicator flashes slowly.

    If the BLUETOOTH device which has been connected before is nearby, the speaker may be connected to the device automatically, and then the(BLUETOOTH) indicator may be lit. In this case, turn off the BLUETOOTH function on the BLUETOOTH device or turn off the BLUETOOTH device.

    When the speaker has no pairing information, for example when you use the BLUETOOTH function for the first time after purchase, the (BLUETOOTH) indicator keeps double flashing in blue.

  2. Press the ST PAIR (Stereo Pair) button behind the cap on the rear side of one of the 2 speakers.

    You hear a beep and the(BLUETOOTH) indicator and the ST PAIR (Stereo Pair) indicator flash. In about 6 seconds, the ST PAIR (Stereo Pair) indicator will stop flashing and stay lit with a beep.

  3. Press the ST PAIR (Stereo Pair) button behind the cap on the rear side of another speaker.

    The ST PAIR (Stereo Pair) indicator lights up.

    You hear the “Left” or “Right” voice guidance from each speaker and both speakers are connected by the Stereo Pair function.

    When a connection with the Stereo Pair function is established, the ST PAIR (Stereo Pair) indicators on both speakers stay lit and the (BLUETOOTH) indicator on either of the speakers turns off.

    Hint

    • When a BLUETOOTH connection is immediately established between 2 speakers, the (BLUETOOTH) indicator and the ST PAIR (Stereo Pair) indicator may not flash and the ST PAIR (Stereo Pair) indicator may light instead.

    • Set up the second speaker within 1 minute. If you do not set it up within 1 minute, the setting of the first speaker will be canceled.

  4. Operate the speaker in which the(BLUETOOTH) indicator is flashing to make a BLUETOOTH connection with a BLUETOOTH device.

    When the BLUETOOTH connection is established, you hear voice guidance (BLUETOOTH connected) from the speaker and the activity of the (BLUETOOTH) indicator changes from flashing to lit.

  5. Start playback on the BLUETOOTH device, and adjust the volume to moderate level.
  6. Press the -/+ (volume) buttons on one of the speakers to adjust the volume.

    Volume adjustment of one speaker is reflected in the other.

To swap the right (right side) and left (left side) audio channels

On either one of the speakers, press and hold the ST PAIR (Stereo Pair) button behind the cap located on the rear side of the speaker.

You hear voice guidance and the right and left audio channels are swapped.

Hint

  • By using “Sony | Music Center,” you can establish a connection with the Stereo Pair function or terminate the Stereo Pair function. This, however, requires that you update the version of the speaker’s software to Ver. 3700 or later on all of the speakers. With the speakers whose software version is earlier than Ver. 3700, “Sony | Music Center” fails to establish a connection with the Stereo Pair function or terminate the Stereo Pair function.

  • When making or receiving a call, only operate the speaker in which the(BLUETOOTH) indicator lights up.

  • If any other BLUETOOTH device(s), such as a BLUETOOTH mouse or BLUETOOTH keyboard, is connected to the BLUETOOTH device that is connected to the speaker, there may be distorted sound or noise in the speaker output. In this case, terminate the BLUETOOTH connection between the BLUETOOTH device and other BLUETOOTH device(s).

  • When using the Stereo Pair function, the codec automatically switches to SBC.

  • If the speaker is already connected with a BLUETOOTH device, touching another NFC-compatible device onto the speaker will disconnect the BLUETOOTH connection with the previous device and establish a BLUETOOTH connection with the new device.

  • Turning off the speaker does not terminate the Stereo Pair function. When the speaker is turned back on, it attempts to establish a connection with the Stereo Pair function. To use the Stereo Pair function, turn on the other speaker within 1 minute.

    While the BLUETOOTH standby function is activated both on the 2 speakers, however, turning on either speaker also turns on the other automatically and establishes a connection with the Stereo Pair function between the 2 speakers.

Note

  • After you restart or initialize either of the speakers while the Stereo Pair function is activated, be sure to press the ST PAIR (Stereo Pair) button on the other speaker to terminate the Stereo Pair function. If you continue to use the speaker without terminating the Stereo Pair function, you will have a problem, such as a failure to establish a BLUETOOTH connection or a sound interruption.

  • When you make a BLUETOOTH connection by One-touch (NFC), touch the speaker in which the(BLUETOOTH) indicator flashes. The device cannot make a BLUETOOTH connection with the speaker when the(BLUETOOTH) indicator is turned off.

  • While the speaker is in AUDIO IN mode, you cannot use the Stereo Pair function.

    If a portable audio device, etc. is connected to the speaker’s AUDIO IN jack, the speaker automatically switches to AUDIO IN mode, and the Stereo Pair function is terminated.

  • Be sure to close the cap completely after using the ST PAIR (Stereo Pair) button. The cap plays a very important role in maintenance of the waterproof and dust proof performance.
