1. परिचय
The Axxess Metra AX-ADCT2 is a 2-channel differential converter designed to facilitate the integration of aftermarket audio components into a vehicle's factory sound system. This device allows for the connection of an aftermarket head unit to a factory amplifier or the addition of an aftermarket amplifier to a factory system, converting high-level speaker signals to low-level RCA outputs.
प्रमुख वैशिष्ट्ये:
- 2-channel input for speaker-level signals
- 80-watt maximum input handling
- 6:1 step-down ratio with variable output adjustment
- Separate level adjustment for each channel (Left and Right)
- Gold-flashed RCA outputs for optimal signal transfer

स्थापना चरण:
- स्पीकर वायर ओळखा: Locate the factory speaker wires from the head unit or factory amplifier that you intend to use as the input for the AX-ADCT2. Typically, these are the rear speaker wires for subwoofer applications or front speaker wires for full-range ampबंधन
- Connect High-Level Input: Connect the factory speaker wires to the corresponding high-level input terminals on the AX-ADCT2. Ensure correct polarity (positive to positive, negative to negative) for each channel (Left and Right). The AX-ADCT2 features a 'Hi-IN' input section with 'L' and 'R' terminals.
- पॉवर आणि ग्राउंड कनेक्शन:
- कनेक्ट करा ग्राउंड wire (usually black) from the AX-ADCT2 harness to a clean, unpainted metal surface on the vehicle chassis.
- कनेक्ट करा 12V Constant Power wire (usually yellow) from the AX-ADCT2 harness to a constant 12V power source.
- कनेक्ट करा रिमोट चालू wire (usually blue) from the AX-ADCT2 harness to the remote turn-on output of your aftermarket head unit or to a switched 12V source that turns on with the ignition. This wire will provide the remote turn-on signal for your aftermarket ampलाइफायर
- आरसीए आउटपुट कनेक्ट करा: Connect RCA cables from the 'OUTPUT' jacks on the AX-ADCT2 to the RCA input jacks on your aftermarket ampलाइफायर
- आउटपुट पातळी समायोजित करा: The AX-ADCT2 features separate variable level adjustments for each channel. Use a small screwdriver to carefully adjust these potentiometers to match the input sensitivity of your aftermarket amplifier. Start with the levels at their minimum setting and gradually increase them until the desired output is achieved without distortion.
- चाचणी प्रणाली: Reconnect the vehicle's battery. Turn on the audio system and test for proper functionality. Adjust the level controls on the AX-ADCT2 and your amplifier as needed to achieve balanced sound.
5. ऑपरेटिंग सूचना
Once properly installed, the AX-ADCT2 operates automatically. When the vehicle's audio system is turned on, the converter will activate, providing a low-level RCA signal to your aftermarket amplifier. The remote turn-on output will also activate, turning on the connected amplifier. The variable output controls allow you to fine-tune the signal level to prevent distortion and achieve optimal sound quality from your ampलाइफायर
6. देखभाल
The AX-ADCT2 is designed for reliable, maintenance-free operation. However, periodic checks can ensure continued performance:
- कनेक्शन तपासा: Periodically check all wiring connections to ensure they remain secure and free from corrosion. Loose connections can lead to signal loss or intermittent operation.
- स्वच्छ युनिट: If necessary, gently wipe the exterior of the converter with a dry, soft cloth to remove dust. Do not use liquid cleaners.
- पर्यावरण तपासणी: Ensure the mounting location remains free from excessive heat, moisture, or physical damage.
