CONNECTIONS + CONTROLS A592DSP
1* In some cases with old headunits the Auto-Turn-On function cannot work. If you meet this problem, please connect
“ACC-IN” wire to 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.
MOUNTING INSTRUCTIONS A592DSP
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. Find a place for the A592DSP and connect the provided (or optionally available car-
specic) wire harness to the amp.
4. Optionally: For more power output please follow these steps: Run a 10 mm2power
wire from the (+) pole of the battery to the (BATT) terminal of the amplier. Use a fuse
with the related value of the cross section of the power wire. The distance
between the B+ pole and the fuse holder must be 30 cm or less. Run the minus cable
with the same cross section from the (GND) terminal of the amp to the vehicle chassis
ground. Make sure that the contact surface is clean in order to get best conductance.
5. Optionally: For Hi-Res Sound from your smartphone: Connect the optical and
coaxial cables to the inputs of A592DSP 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 amplier without passing any D/A converter.
6. Optionally: Connect the remote control for convenient operation of the Master Volume,
Bass Extender and Mute function. Recommended when using A592DSP without any
headunit.
7. Connect the wire to the headunit.
8. Install the headunit back in the dashboard.
1REMOTE CONTROL
Connect the optional RC for convenient operation 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
you are not able to adjust the volume with your iPhone. Therefore you need to
connect the separate available RC.
2ANTENNA
External Bluetooth antenna of the audio streaming BT module, called “BT Audio” in your
mobile settings. The second BT module, called “A592DSP” is for doing the adjustments
only and does not need a separate antenna.
3POWER TERMINAL
Connect Ground and Battery cables when additional power is necessary or desired.
4FUSE
If the fuse is broken, replace it with a new fuse of same value.
5COAXIAL
This input provides power for the ABT50 and also receives audio data from this device.
It’s impossible to connect usual USB sticks.

Time Alignment
Press the „Time Alignment“ button to go
to the menu. In this menu you can apply a
time delay to the speaker signal to simulate
an ideal listening position. Note the
distance between your listening position
and each speaker. Choose the most distant
speaker as the reference for the other
speakers.
Time Aligment
With the aid of the following example,
calculate the values for your speakers:
(FL) front left is 0.80 m from the listening position
(FR) front right is 1.40 m from the listening position
(RL) rear left is 0.50 m from the listening position
(RR) rear right is 1.30 m from the listening position
(SubW) subwoofer is 2.00 m from the listening position
Value for FL = SubW – FL → FL = 2.00 – 0.80 m
Value for FR = SubW – FR → FL = 2.00 – 1.40 m
Value for RL = SubW – RL → RL = 2.00 – 0.50 m
Value for RR = SubW – RR → RR = 2.00 – 1.30 m
SubW remains at the value „0“
Note the distance
between your
listening position
and each speaker.
