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 [Technics Audio Connect] app, tap [SETTINGS], tap [Connection mode] and switch [LDAC for headphones] 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.
