Helix AAC.2
Original factory sound systems typically have a significant disadvantage – they don’t offer any pre-amp output for driving additional amplifiers.
Here’s where the new HELIX AAC.2 comes into play, it generates a perfectly conditioned pre-amp signal from a speaker level output from an arbitrary car radio or amplifier.The new AAC is more intelligent than any other signal converter on the market today. Its “Double Activation Circuit“ generates a remote signal for controlling external amplifiers in two different manners.
Either it will detect the DC offset on the speaker output of typical factory radio or it uses an integrated signal detection circuit with variable input sensitivity that can be activated as an additional feature. -
Helix HEC HD-AUDIO USB-INTERFACE – DSP MINI
The HD-AUDIO USB-INTERFACE extends HELIX devices with a High Resolution Audio USB input and converts a PC or smartphone into a HD-Audio player.
The direct digital signal transmission (without additional AD-DA conversion) from the music source to the DSP with up to 192 kHz / 32 Bit allows lossless audio processing and thus assures perfect sound quality.

Helix HEC BT – DSP MINI
The HELIX Extension Card BT extends HELIX devices with a Bluetooth® Audio Streaming function and an optical digital output in SPDIF format.
Due to the support of the Qualcomm® aptX™ codec and A2DP codec, wireless audio streaming in CD-like audio quality is possible.
Furthermore, the direct signal transmission (without additional AD-DA conversion) from the BT module to the DSP allows lossless audio processing and thus outstanding sound performance.
The module will be delivered with a device-specific side panel and provides compatibility with all devices featuring Bluetooth® wireless technology.

Helix AAC.3
The integration of car hifi components into existing OEM sound systems becomes more and more challenging as today’s factory radios either lack of preamplifier outputs or incorporate intelligent speaker diagnosis features. That’s where the new Helix AAC.3 comes into play.
The smartest high-low converter in its class
Forget about error messages or loss of features (e.g. the fader) – the integrated ADEP.3 circuit cleverly “bypasses” the speaker diagnosis in factory car radios. Distorted sounds and increased THD which may occur with conventional high-low converters are prevented as well. The good thing is that the ADEP.3 doesn’t load the car radio’s amp unnecessarily and therefore reduces its current draw by up to 70 %.
