Safety Precautions

This user manual contains important recommendations for the safe and proper operation of the device. Please follow all instructions carefully.

1. When installing the unit, avoid areas with high temperature, humidity, or excessive dust.
2. Ensure the unit and its accessories are kept out of reach of children.
3. Do not drop the unit or subject it to impacts, as this may cause damage.
4. The manufacturer is not responsible for any data loss resulting from damage, repair, or other causes related to this unit.
5. Do not attempt to disassemble the unit yourself, as this will void the warranty.
6. Do not use alcohol, solvents, or gasoline to clean plastic parts or the display. Use only a soft, dry cloth.
7. Avoid contact with liquids.
8. This product is designed for use with 12-volt DC negative-ground electrical systems only. Using it in positive-ground systems or with voltages other than 12 volts may cause damage to the vehicle and the unit.

IMPORTANT: The unit features high-voltage RCA outputs with a signal amplitude of up to 4 volts!

When connecting external amplifiers:

1. Set the input sensitivity (GAIN) on the external amplifiers to the leftmost position (minimum) first.
2. Correctly match the input sensitivity. The amplifier may distort if the input level exceeds the required level.

DTA Setting (Delays)

IMPORTANT: Delay settings start with the furthest speaker from the listening position (usually the subwoofer). The furthest speaker requires no additional delay. Other speakers must be adjusted according to the difference between the distance from the furthest speaker and the distance from the speaker in question to the listening position.

Example: Listener to subwoofer distance is 220cm, listener to front left tweeter distance is 80cm. The delay for the left tweeter channel will be: 220cm - 80cm = 140cm. Enter 140 into the left tweeter channel delay setting.

Perform necessary calculations for all speakers, then apply settings in the AURA AUDIO app or the receiver menu.

Delay (Distance / Delay) - Setting for each channel

Select the desired channel and set the required signal delay.

Delay values for SUB (subwoofer) channels are adjusted synchronously.

Steering Wheel Control Programming (Direct SWC)

This function can only be implemented in vehicles with resistive steering wheel controls, where the common control wire is connected to the vehicle's chassis ground.

For correct operation of the steering wheel controls, first connect the factory remote control wires to the ISO connector (section A).

The operating voltage range for connected remote control buttons is 0.3 to 3.3 V. The minimum difference in operating voltages registered by the unit after button presses should be at least 0.3 V; otherwise, buttons may be recognized as a single input.

ATTENTION! The manufacturer does not guarantee correct operation with all car models and is not responsible for potential issues with the vehicle or unit arising from incorrect connection to the factory wiring.

For correct connection of a factory resistive remote control, consult your vehicle's official dealer or a certified installation center.

Button Programming Procedure:

1. Navigate to the SYSTEM menu.
2. Enter the SWC section and select one of the two memory banks (SWC 1 or SWC 2).
3. Go to the ENABLE menu item and select YES.
4. Press the "Back" button and select the PROGRAM option. The message "PRESS KEY 1" will flash on the display.

Perform the following steps:

1. Press the button on the steering wheel to assign a function to it. The message "CHOOSE KEY 1" will flash on the display.
2. Select one of the buttons on the head unit whose function you want to assign. Upon successful assignment, the message "PRESS KEY 2" will flash on the display.
3. Repeat steps (1-2) for as many steering wheel buttons as you need to assign functions to.
4. Press the volume knob on the front panel to save the data. The message "SAVED x KEYS" will appear on the display, and the unit will return to the SWC menu.
