The HELIX Extension Card OPTICAL IN extends HELIX devices with an optical input in SPDIF format (stereo PCM only) for connecting digital signal sources with sampling rates up to 96 kHz.
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 HELIX Extension Card OPTICAL IN extends HELIX devices with an optical input in SPDIF format (stereo PCM only) for connecting digital signal sources with sampling rates up to 96 kHz.
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.
The module will be delivered with a device-specific side panel are part of the price.
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.
