Audison APFRD F150 8.9

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.

Simply clever – the HELIX SDMI25 is the “smartest solution” to integrate DSP products into vehicles with premium sound system.
In many premium vehicles, the audio signal is embedded in the MOST data stream which enables lossless and interference-free communication between the individual components. The SDMI25 automatically detects the music signal within the MOST25 data stream and outputs it as a highest quality digital stereo signal in SPDIF format. Thanks to its optical digital output, signal processors and DSP amplifiers that are equipped with a digital SPDIF input can be fed with a perfect audio signal.

By simply setting jumpers, the SDMI25 can be adapted to the respective car model. The adjustment of the volume, balance and tone control  via the original radio remains unchanged.
As a special highlight – when used in BMW vehicles – the volume of the on-board warning signals (e.g. of the parking sensors) can be adjusted and thus perfectly adapted in relation to the audio signal.

In various car models the MOST25 components are protected by a serial number. The SDMI25 automatically detects and copies this number from the component to be replaced and finally logs on to the MOST data bus automatically.
