Helix BT HD Streamer with BT HD Hands-Free Microphone Kit

Stand-alone Bluetooth® audio streaming module

       The HELIX BT HD STREAMER is the stand-alone Bluetooth® audio streaming tool for audiophiles who appreciate high-quality yet uncomplicated wireless audio transmission in their vehicle. Equipped with the Qualcomm® aptX™ HD codec, this streamer guarantees high-definition sound quality that lets your music collection shine in a new light on every ride. Of course, full compatibility with all Bluetooth® devices is guaranteed, therefore nothing stands in the way of streaming your favorite tracks.

 
High-definition streaming with maximum flexibility

       The HELIX BT HD STREAMER combines modern high-definition audio streaming with extraordinary practical benefits. Thanks to its optical output, it can be conveniently connected to DSPs and DSP amplifiers as part of a completely digital, lossless signal routing. In addition, we implemented a digital input with pass-through function: this allows the incoming signal to be forwarded directly to the optical output and guarantees optimum flexibility without losing this digital signal way – ideal for audio setups including the integration of an additional digital audio player. Thanks to its standby mode, the streamer provides audio enjoyment, particularly in vehicles with a special demand for comfort and efficiency as well as smart retrofit solutions. This makes it especially advantageous in motorhomes and campers as well as classic cars without a modern head unit.

 
Exceptional sound quality due to state-of-the-art streaming technologies

       Thanks to the integration of the Qualcomm® aptX™ HD codec, our streamer always offers sound quality at the highest level. This advanced codec enables high-definition Bluetooth® audio transmission, providing extraordinary depth and clarity and creating an exceptional sound experience for even the most discerning listeners. Streaming in its highest standard with an authentic, wireless connection at 24 bit and 48 kHz. In addition, there are significant improvements in the signal-to-noise ratio, the minimization of total harmonic distortion (THD) and the elimination of audio artefacts, ensuring the reproduction of your favourite in the best possible way. Our BT HD STREAMER supports the regular Qualcomm® aptX™ codec as well, assuring improved audio quality even for users of older devices with Bluetooth® wireless technology. Last but not least, we also implemented the Bluetooth® codec AAC, which is specially optimized for Apple users. This codec ensures high-quality audio transmission for devices from the Apple ecosystem, offering iPhone and iPad users outstanding music enjoyment.

 

Efficiency and convenience: The standby mode

       Modern streaming is characterized by user-friendliness and convenience at the highest level. In line to this, it was essential for us to implement a standby mode in our streamer: The standby mode is activated via a simple switch, putting the HELIX BT HD STREAMER into an energy-saving mode with just 3mA power consumption. As soon as a smartphone connection to the streamer is established, it “awakens” and generates a remote signal, which in turn switches on the entire sound system. This seamless transition ensures convenient music enjoyment without having to turn on the ignition while at the same time preserving the vehicle battery, offering particular advantages in classic cars without a head unit or in campers and motorhomes.

 

Optional hands-free function: communication made easy

       The integration of the optional hands-free function clearly sets the HELIX BT HD STREAMER apart from other Bluetooth® streaming devices on the market. With the separately available Microphone Kit, the streamer transforms your vehicle into a modern communication center – even without a head unit.
Here, especially the Echo Cancelling and Noise Suppression technologies of the STREAMER come into play:

  • Noise Suppression (Noise Cancelling): The algorithm in the BT chip of the HELIX BT HD STREAMERS filters out background noises such as vehicle sounds and road noise, enabling clear communication during driving.
  • Echo Suppression: This function prevents echoes during the conversation by minimizing the audio feedback between the speaker and the microphone, improving the quality of the conversation.
  • Voice Enhancement: This optimizes the driver’s voice recording by improving the clarity and intelligibility of the voice and reducing background noise. In addition, the automatic volume correction adjusts differences in conversation volume, making even distant persons easily understandable.

 

Features
  • Stand-alone Bluetooth® audio retrofit with optional hands-free function for all DSPs and DSP amplifiers with optical digital input
  • Wireless high definition audio streaming in exceptional sound quality with up to 24 Bit / 48 kHz from a mobile device to your DSP or DSP amplifier
  • The best possible audio streaming quality for Android and Apple devices thanks to modern, market leading audio codecs such as Qualcomm® aptX™ HD, Qualcomm® aptX™ and AAC
  • Optional “HELIX BT HD Hands-Free Microphone Kit” for hands-free calling in the best audio quality
  • Standby mode, allowing the the sound system activation via Bluetooth® signal
  • Extremely low power consumption in standby mode (approx. 3 mA) to conserve battery life
  • Perfect for retrofitting classic cars without head units
  • Allows music consumption via the vehicle sound system without turning on the ignition – perfect for e.g. camper vans or motor homes
  • Integrated digital input with passthrough function enables the connection of an additional signal source with optical digital output – for example, if a head unit or digital audio player is also to be integrated into the sound system
  • Offers the option of integrating Bluetooth® audio streaming into sound systems in which the HEC slot of the DSP or DSP amplifier is already occupied
  • Provides external pairing by retrofitting control cables with an external pushbutton – practical for hidden module integrations, e.g. behind the glove compartment
  • Suitable for all BRAX, HELIX and MATCH DSP products with optical digital input

Hands-Free Functionality for the HELIX BT HD STREAMER

The BT HD Hands-Free Microphone Kit is the perfect addition to the BT HD STREAMER and enables seamless integration of a convenient hands-free functionality with superior audio quality, without the need for any modifications of the head unit.

Voice-optimized Frequency Response

The microphone features an optimized cardioid polar pattern for clear voice recordings. This is specifically designed to precisely capture the driver’s voice while effectively reducing ambient noise for crystal-clear communication during the drive.

Echo Cancelling and Noise Suppression Technology:

  • Noise Suppression (Noise Cancelling): The algorithm in the BT chip of the HELIX BT HD STREAMERS filters out background noises such as vehicle sounds and road noise, enabling clear communication during driving.
  • Echo Suppression: This function prevents echoes during the conversation by minimizing the audio feedback between the speaker and microphone, improving the sound quality of the conversation.
  • Voice Enhancement: This optimizes the driver’s voice recording by improving the clarity and intelligibility of the voice and reducing background noise. In addition, the automatic volume correction adjusts differences in conversation volume, making even distant persons easily understandable.

Convenient Control Options

For the specialist dealer or experienced DIY installer, the included cable set enables the connection of “optional buttons”, allowing important functions such as “track forward”, “track back” and “accept call” or “reject call” to be controlled externally. It also offers easy pairing of new smartphones for maximum flexibility and convenience.

Made in Germany

The microphone is manufactured with the highest precision and quality in Germany. This ensures that you receive a product that meets the highest standards and provides outstanding performance.
