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 %.
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.
The module will be delivered with a device-specific side panel are part of the price.
The HELIX Extension Card AUX IN extends HELIX devices with a 3.5 mm AUX input for connecting analog sources like smartphones.
Furthermore, the module provides an additional optical digital output in SPDIF format.
