Exceptional sound quality with the latest streaming technologies
The HELIX BT HD STREAMER integrates the Qualcomm aptX HD codec, which enables 24-bit/48 kHz Bluetooth audio transmission for Hi-Res playback, with professional-grade dynamics and transparency. The result is richer, more detailed, and more natural sound, perfect for the most discerning listeners.
By reducing background noise, minimizing total harmonic distortion (THD), and eliminating digital artifacts, every song is reproduced with extraordinary fidelity.
The device also supports the Qualcomm aptX and AAC codecs, offering maximum compatibility with both Android and Apple devices (iPhone, iPad) and always ensuring stable, high-quality transmission.
Efficiency and convenience: intelligent standby mode
The HELIX BT HD STREAMER is designed for maximum ease of use even in the most complex installations.
Standby mode reduces power consumption to just 3 mA, helping to preserve the vehicle's battery.
As soon as a smartphone connects via Bluetooth, the device automatically activates and generates a remote start signal, starting the entire audio system without the need to manually turn on the system or ignition.
This feature is particularly advantageous for classic cars, campers, and audio installations without a head unit, where a seamless, efficient, and always-ready listening experience is desired.
Optional Hands-Free Function
The HELIX BT HD STREAMER also features an optional hands-free function, which, when combined with the dedicated BT HF MICR microphone kit (available separately), transforms any vehicle into a modern and secure Bluetooth communications hub.
Thanks to advanced echo cancellation and noise suppression technologies, call quality is always impeccable:
- Noise Canceling: The integrated Bluetooth processor filters out ambient noise (engine, road, wind) for clear conversations even while driving.
- Echo Cancellation: Eliminates annoying feedback between the microphone and speaker.
- Voice Enhancement: Optimizes voice clarity and intelligibility, automatically adjusting the volume based on listening conditions.
A versatile, efficient, and cutting-edge system designed by Audiotec Fischer for those seeking a premium audio experience and next-generation HD Bluetooth connectivity.
