1. Входное соединение: Connect the positive (IN+) and negative (IN-) terminals of the crossover to the corresponding positive and negative speaker output terminals of your ampприемник или передатчик.
2. Подключение низкочастотного динамика: Connect the positive (W+) and negative (W-) terminals of the crossover to the positive and negative terminals of your woofer speaker.
3. Подключение твитера: Connect the positive (T+) and negative (T-) terminals of the crossover to the positive and negative terminals of your tweeter speaker.

Note: Soldering may be required to secure speaker wires to the crossover terminals for a reliable connection.

Mount the crossover board securely within your speaker enclosure or vehicle panel, ensuring it is protected from moisture, excessive heat, and physical damage. Use non-conductive standoffs or mounting hardware if available to prevent short circuits. The board has mounting holes for this purpose.

5. Инструкция по эксплуатации

Once correctly installed, the DollaTek 2-Way Speaker Audio Crossover Filter operates passively. It requires no external power or adjustments. The crossover automatically filters the audio signal from your amplifier, directing appropriate frequencies to your woofer and tweeter for balanced sound reproduction.

After installation, power on your amplifier and test the sound. Ensure both the woofer and tweeter are producing sound clearly and without distortion. Adjust your amplifier's volume and tone controls as desired.

6. Техническое обслуживание

The DollaTek 2-Way Speaker Audio Crossover Filter is a passive electronic component and requires minimal maintenance.

• Хранить в сухом месте: Ensure the crossover is installed in a dry environment, away from liquids and excessive humidity.
• Чистота: Periodically inspect the board for dust or debris. If necessary, gently clean with a soft, dry brush or compressed air. Do not use liquid cleaners.
• Физический осмотр: Check connections periodically to ensure they remain secure and free from corrosion.
• Температура: Avoid exposing the crossover to extreme temperatures.

7. Поиск Неисправностей

If you encounter issues after installing the crossover, consider the following troubleshooting steps:

• Нет звука из динамика:
  • Check all connections (amplifier to crossover, crossover to woofer, crossover to tweeter) for proper seating and polarity.
  • Ensure speaker wires are not broken or short-circuited.
  • Test the speaker directly with an amplifier (bypassing the crossover) to confirm the speaker itself is functional.
• Искаженный звук:
  • Убедитесь, что amplifier's power output does not exceed the crossover's maximum power handling (130W) or rated power (100W).
  • Check for loose connections or frayed wires that could cause intermittent contact.
  • Ensure the speakers are correctly matched to the crossover's frequency range and power handling.
• Unbalanced Sound (e.g., too much bass or treble):
  • Confirm correct polarity for all speaker connections. Reversed polarity can cause phase issues.
  • Ensure the crossover is appropriate for your specific woofer and tweeter characteristics.

If problems persist, consult a professional audio technician.
