Helix HEC BT HD – HD Bluetooth audio streaming module for HELIX DSPs
Version: DSP.3S
The HEC BT HD adds high-resolution Bluetooth streaming to HELIX DSP devices. It transmits at up to 576 kbps and 24-bit/48 kHz over Bluetooth 5.0 + EDR, supporting SBC, AAC, aptX and aptX HD. The signal is fed digitally straight into the DSP, avoiding any additional A/D or D/A conversion.
Besides music streaming, the module allows wireless DSP tuning with the DSP PC-Tool on ACO-platform devices and supports control and display functions on HELIX remotes. It also provides an optical SPDIF output. The module is sold in separate versions for each compatible HELIX DSP, each with a device-specific side panel included.
