Setting the BLUETOOTH sound quality (Wireless Playback Quality)
You can set the transmission data rate for BLUETOOTH playback.
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.

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.
