High-resolution audio

With the Qualcomm aptX HD codec, wireless and stable transmission of HD-quality audio is possible. Direct processing of digital signals from the BT HD module into the DSP without additional AD/DA conversion ensures lossless signal handling and exceptional audio performance.

Full control

HEC BT HD supports control commands such as play/pause, track forward/back, connect, pair and disconnect for a connected DSP remote control (e.g., CONDUCTOR and DIRECTOR). The DIRECTOR display also shows the current artist and title as well as the codec in use.
