1* In some cases with old headunits the Auto-Turn-On function cannot work. If you meet this problem, please connect the
"ACC-IN" to the ACC/Amp Remote of the car stereo or another cable which will provide +12 V only when the car stereo
is turned on. Secondly select "REMOTE TURN ON" on the remote switch.
2* REM-Out: Connect this wire to the remote input of a separate amplifier, for example a mono amp for a subwoofer.
POWER
1
Two color LED: Green light shows normal operation. Green light blinking shows a current
data transfer, i.e. receiving data from the app. Red light shows protection mode, i.e. too low
impedance.

This is the main connector for Plug & Play installation.
ANTENNA

External Bluetooth antenna for data and audio streaming.
OPTICAL OUTPUT CH9/CH10

To send the signals of CH9 and CH10 to another Axton DSP amplifier with optical input.
REMOTE / SIGNAL TURN ON

Connect the optional RC for convenient operating of Master Volume, Bass Volume and Mute
function.
When you are using the ABT50 with OTG for iPhone for lossless audio transmission, the signal
is sent directly avoiding any converter. That's awesome. But it also means that you are not able
to adjust the volume with your iPhone. Therefore you need to connect the separate available RC.

This input provides power for the ABT50 and also receives audio data from this device. It's
impossible to connect usual USB sticks.
A544DSP MOUNTING INSTRUCTIONS
1. Before you start with the installation, make sure you know the security code of your
headunit (if applicable).
2. Remove the headunit from the dashboard and disconnect the main wire harness.
3. Wiring
A) Plug & Play: Find a place for the A544DSP and connect the optionally available car-
specific wire (www.axton.de) to the amp, to the headunit and the cars main wire harness.
Switch
is to be set to "Signal turn on".
5
B) RCA Line In: If you prefer using low level signal, then disconnect the speaker input cables
and connect your headunit and A544DSP with the RCA interconnects. You will also need to
use separate remote/ACC+ cable and switch to "Remote Turn On".
4. For Hi-Res Sound from your smartphone: Connect the optical and coaxial cables to the
inputs of A544DSP and outputs of the AXTON ABT50. Connect your smartphone via
Bluetooth to the ABT50 for using APTX-HD standard or use the AXTON OTG cable for
absolutely lossless audio transmission: the signal is sent from your smartphone directly to the
amplifier without passing any D/A converter.
5. Connect the remote control for convenient operation of the Master Volume, Bass Extender
and Mute function. Recommended when using A544DSP without any headunit.
6. Connect the wire to the headunit.
7. Install the headunit back in the dashboard.
Stand-alone installation
When you intend to use the A544DSP without any headunit, please connect the optionally
available N-A480DSP-ISOFLX cable and connect the wires according to the wiring diagram.
Switch (4) is to be set to "Remote turn on".
