Setting BLUETOOTH audio codecs (Bluetooth Codec - AAC/Bluetooth Codec - LDAC)

You can enable and disable AAC (Advanced Audio Coding) or LDAC audio.

  1. Select [Setup] - [Bluetooth Settings] from the home menu.
  2. Select [Bluetooth Codec - AAC] or [Bluetooth Codec - LDAC].
  3. Select the setting you want.
    • On: AAC and/or LDAC audio is available if the BLUETOOTH device supports AAC or LDAC.
    • Off: AAC and/or LDAC audio is not available.


  • When you change these settings, the settings are applied from the next time you connect the BLUETOOTH device.
  • These functions work only when the [Bluetooth Mode] is set to [Receiver] or [Transmitter].
  • While a BLUETOOTH device is connected, the settings of these functions cannot be changed.


  • You can enjoy high-quality sound if AAC or LDAC is enabled.
  • LDAC is an audio coding technology developed by Sony that enables the transmission of High-Resolution (Hi-Res) Audio content, even over a BLUETOOTH connection. Unlike other BLUETOOTH compatible coding technologies such as SBC, it operates without any down-conversion of the Hi-Res Audio content (*1), and allows approximately three times more data (*2) than those other technologies to be transmitted over a BLUETOOTH wireless network with unprecedented sound quality, by means of efficient coding and optimized packetization.
