Helix HEC BT HD - DSP Pro MK3

The BT HD expansion card adds Bluetooth audio streaming functionality in HD quality of up to 576 kb/s and 24 bits at 48 kHz thanks to the BT5.0 standard. Supported audio codecs are SBC, AAC, aptX and aptX HD. The board also features an optical SPDIF digital output.

High-resolution sound

Thanks to the Qualcomm aptX HD audio 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 further ensures lossless signal handling and thus 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, track title and the audio codec currently in use.
