Audio-interface MOST-AiNet 2.0 (Adapter for digital output)
Fig.1. Audio-interface
Most-AiNet 2.0
The adapter allows you to integrate sound processor Alpine PXA-H800 with amplifiers in the car's audio
system instead of the original amplifier. This makes it possible to build a high quality audio system. It is also
possible to use any audio processor that has a digital TosLink audio input.
It is compatible with vehicles equipped with audio system with optical interface MOST (except MOST150):
- Audi A4, A5, A6, A8, Q5, Q7 (MMI 2G/3G/3G+ (up to 2014)
- BMW (E60, E70, E90, F10, F30…), except E65
- Land Rover (Freelander 2, Discovery 3, 4), Range Rover
- Mercedes Benz (2008+)
- Porsche
- Volvo (S40, S60, S80, XC70, XC90)
- VW Touareg NF (3G+)

Description
Audio-interface MOST-AiNet:
1) emulates a original power amplifier.
2) select the main stereo signal from the optical stream, as well as additional audio signals from the phone, navigation system, parking sensors
and other messages.
3) performs mixing of additional signals to the main signal in the respective proportions for each audio channel using digital mixers.
4) generates at its output 24-bit digital signal TosLink. The digital output signals are formed by the left and right channels, which are mixed in
signaling intended for the front and for the rear speakers.
5)
stores in the system basic settings (high, low, balance), when you connect the Alpine PXA-H800 – fader, subwoofer.
6) provides control of the sound processor Alpine PXA-H800 via AiNet interface.
7)
allows the use of a sound processor Alpine PXA-H800 without remote RUX-C800.
8) allows you to use two presets processor Alpine PXA-H800.
9) uses throughout the audio path only digital (24 bit) format for the signals.
10) play audio from the DVD source is only possible in Stereo mode. The device does not have built-in multichannel decoder 5.1 audio, so
when you try to play any 5.1 audio signal will not be broadcast.

Connection
Attention
:
Color of wires of the power cable does not match the color of the regular car
wiring. Incorrect connection of the supply leads to the device failure.
1) set the jumpers according to Fig.4.
2) to connect the adapter to the car system has:
- connector “MOST” (Fig.2). Before connecting remove the cover.
- connector “Power” and Power cable:
Red wire (+12V Battery).
Black wire (Ground, GND).
The blue wire is used for switching between "presets" of sound processor (free
state – Preset1, grounded – Preset2). Switching is permitted in any state of the
system. The settings of presets
must be saved
in the processor.
3) to connect to the processor PXA-H800 adapter has connectors TosLink and AiNet
(Fig.1).
Notes for BMW and Mercedes Benz:
If the optical amplifier is not in the original vehicle specification:
- It is necessary to register in the configuration of the vehicle using the diagnostic equipment,
- To connect the adapter, you will also need an optical cable (not supplied).
Notes for BMW:
If you want to change the volume levels of parking sensors and signals of system messages, there is an additional mode of the adapter
(in the fig.4 labeled as "BMW Park Volume"). More about this mode later.
Notes for Mercedes Benz (only for Comand NTG2.5):
- It is necessary to activate function “Rearseat entertainment”.
Notes for Volvo (if you have activated component protection):
- Before connecting the adapter must be assigned to the adapter serial number (activity flag of the protection components is to stop
transmission of audio through the adapter 20 to 40 seconds after switching on the system),
- To connect the adapter, you will also need an optical cable (not supplied).
