Bluetooth 5.0 LDAC
This version of the Topping D70 BT is equipped with a particularly powerful Bluetooth 5.0 CSR8675 chip and offers it Hi-Res Audio Wireless certification. It thus supports Bluetooth transmission protocols AAC, SBC, aptX, aptX LL, aptX HD and LDAC. This last protocol, LDAC, developed by Sony, allows the transmission of files with high sampling rates up to 24bit 96kHz.
The signal received by the Bluetooth chip is then converted by the two AK4497 chips, which are much more powerful than the DAC embedded in the Bluetooth chip.
