Sound and audio volume

What is LDAC?

  • LDAC codec contains about 3 times the amount of information compared to general codec like SBC.
    It is the Bluetooth® transmission codec which enables to transmit the maximum 96kHz/24bit high resolution sound quality.
    * Default setting of LDAC is OFF.
    * LDAC setting can be changed with the Technics Audio Connect app.

Why is there is an interference (static audio, skipping, etc.) when listening to LDAC audio?

  • Step1 : Move to a place where is no interference. If still there is interference try step 2.
  • Step2 : Change the bit rate setting of the playback device to auto adjustment mode (e.g. Best effort). How to change the setting depends on each device.
    << In case the device is DAP >>
    Switch the sound quality setting from "Priority on sound quality" to "Priority on stable connection" (e.g. Best effort).
    << In case the device is Android smartphone >>
    Go to the setting of developer option to change the LDAC codec sound quality by reducing the bit rate (e.g. Best effort).
    * See the operating instruction book of the device.
    * Some devices may not be able to change the setting. If still there is interference try step3.
  • Step3 : Disable the LDAC function as follows.
    Open the "Technics Audio Connect" app and switch the "LDAC for headphones" to OFF or "Prioritize connectivity" to OFF.

Why the settings of the earphones did not change even though the "Prioritize connectivity" was changed to OFF?

  • Switch the Bluetooth settings of your device OFF and ON.
