Helix HEC BT HD - DSP Ultra

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

High-resolution sound

Thanks to the Qualcomm^® aptX^™ HD audio codec, wireless and stable HD-quality audio transmission is possible. Direct processing of digital signals from the BT HD module into the DSP without additional AD/DA conversion furthermore ensures lossless signal handling and therefore unique sonic 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, title and the audio codec currently in use.
