Helix BT HD STREAMER – stand-alone Bluetooth HD audio streamer
The HELIX BT HD STREAMER is a stand-alone Bluetooth audio retrofit for car audio systems. It streams in high definition up to 24-bit/48 kHz and passes the signal digitally via its optical output to a DSP or DSP amplifier. Hands-free calling can be added with the optional HELIX BT HD Hands-Free Microphone Kit.
Thanks to its standby mode the module can switch on the sound system as soon as a Bluetooth connection is established, which makes it well suited to classic cars without a head unit as well as campers and motorhomes.
Key Features
- HD streaming: up to 24-bit/48 kHz with aptX HD, aptX, AAC and SBC codecs for Android and Apple devices
- Bluetooth 5.0 with EDR: A2DP, AVRCP and SPP profiles; range up to 10 m; memory for up to 8 paired devices
- Optional hands-free: with the BT HD Hands-Free Microphone Kit, including noise suppression, echo suppression and voice enhancement
- Standby mode: switches on the sound system on Bluetooth connection; standby draw approx. 3 mA
- Digital pass-through: optical S/PDIF input passed through to the optical output for adding a second digital source
- External pairing: via a pushbutton on the remote control cables – useful for hidden installation
- Wide supply range: 10.5–32 V operating voltage (12/24 V), remote output up to 200 mA
Compatibility
- All BRAX, HELIX and MATCH DSP devices with optical input
- DSPs and DSP amplifiers with an optical digital input
Installation Notes
- Pairing can be triggered by an external pushbutton on the remote cables, so the streamer can be mounted out of sight.
