Helix HEC BT HD - V Eight DSP

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 BT5.0. Supported audio codecs are SBC, AAC, aptX and aptX HD. The board also features an optical digital output in SPDIF format.

High-resolution sound

Thanks to the 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 further ensures lossless signal processing and outstanding 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 and the currently used audio codec.
