Setting the BLUETOOTH sound quality (Wireless Playback Quality)

You can set the transmission data rate for BLUETOOTH playback.

  1. Select [Setup] - [Bluetooth Settings] from the home menu.
  2. Select [Wireless Playback Quality].
  3. Select the setting you want.
    • LDAC Sound Quality: Enables LDAC codec and the highest bit rate is used. Sound is sent in a higher quality; however, audio playback sometimes may become unstable when the link quality is not good enough. If audio playback is unstable in this mode, select [LDAC Stable Connection (Auto)].
    • LDAC Stable Connection (Auto): Enables LDAC codec and the data transfer rate is automatically changed depending on the environment.
    • SBC Sound Quality: Enables SBC codec. A medium data rate is used. This provides a balance between sound quality and playback stability.
    • SBC Stable Connection (Auto): Enables SBC codec and the data transfer rate is automatically changed depending on the environment. This setting is recommended if the connection is unstable.

Note

  • This function is only available when [Bluetooth Mode] is set to [Transmitter].

Hint

  • LDAC is an audio compression technology that enables transmission via BLUETOOTH of high-resolution audio sources, developed by Sony. Unlike the existing compression technology for BLUETOOTH such as SBC, it processes high-resolution audio sources without down-converting them to low frequencies and low bit numbers (*1). In addition, by applying extremely efficient coding and optimizing packet distribution, it is possible to transmit data volume that is about three times that of conventional technology (*2), realizing unprecedented high-quality BLUETOOTH wireless transmission.

*2 Comparison with SBC (Subband Coding) when a bit rate of 990 kbps (96/48 kHz) or 909 kbps (88.2/44.1 kHz) is selected
