Helix HEC BT HD - P Six DSP Ultimate

The BT HD expansion card adds Bluetooth audio streaming functionality in HD quality up to 576 kb/s and 24‑bit at 48 kHz thanks to the BT 5.0 standard. Supported audio codecs are SBC, AAC, aptX and aptX HD. The board also includes an optical digital SPDIF output.

High-resolution sound

Thanks to the Qualcomm^® aptX^™ HD audio codec, wireless and consistent HD-quality audio transmission 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 unique 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.
