3. 제품 오버view

The BOMGE UHF Wireless Antenna Distribution System centralizes antenna management for multiple wireless microphone receivers. It features active directional antennas that utilize a log-periodic array to enhance RF signal reception and rejection of signals outside the coverage area. The system offers 18 gain settings (up to 12dB) to compensate for insertion loss, extending coverage up to 988ft/300m.

4. 설정 지침

Follow these steps to set up your BOMGE UHF Wireless Antenna Distribution System:

1. 안테나 배치: Position the directional antennas strategically. The installation height should be higher than 1.8 meters. Ensure the antennas are within the range of the signal transmitter and at least 1.5 meters from the periphery, avoiding obstacable blocks. Keep antennas away from large metal objects and various signal interference sources. When used outdoors, place the antenna in a dry position.

2. Connect Antennas to Distribution System: Use the two long BNC cables to connect the directional antennas to the 'ANTENNA IN' ports on the rear panel of the distribution system.
3. Connect Distribution System to Receivers: Use the short BNC cables to connect the 'RF OUTPUT' ports (A1-A4 and B1-B4) on the distribution system to the antenna input ports of your wireless microphone receivers. The system supports up to 8 receivers.
4. Powering Receivers: Utilize the included DC power lines to power your wireless microphone receivers directly from the distribution system's DC output ports (12V 150mA MAX OUT). This eliminates the need for separate power adapters for each receiver.
5. Cascade Connection (Optional): If you need to connect more than 8 receivers, use the 'CASCADE' output port to link to another BOMGE antenna distribution system.
6. 시스템에 전원을 공급하세요: Connect the provided power supply unit to the 'DC INPUT' port on the distribution system and plug it into a power outlet.

5. 사용 설명서

Once the system is set up, power on the distribution unit and your wireless microphone receivers. The active directional antennas will provide enhanced signal reception. Adjust the gain settings on the directional antennas (18 settings, up to 12dB) as needed to optimize signal strength and compensate for cable loss or distance. Ensure the antennas are pointed towards the general area of the wireless microphone transmitters for best performance. The system is designed to minimize interference and dropouts, providing a stable and clear audio signal.

6. 유지관리

To ensure the longevity and optimal performance of your BOMGE UHF Wireless Antenna Distribution System, follow these maintenance guidelines:

• 청소: Regularly wipe the unit and antennas with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
• 저장: When not in use, store the system in a cool, dry place, away from direct sunlight and extreme temperatures. The included carrying case provides excellent protection for transport and storage.
• 케이블 검사: Periodically check all BNC and power cables for any signs of wear, damage, or loose connections. Replace damaged cables immediately.
• 환경 보호: Protect the unit and antennas from moisture, dust, and excessive vibrations. The metal shell and scientific wind-proof exhibition design offer good protection, but care should still be taken, especially in outdoor environments.

7. 문제 해결

If you encounter issues with your BOMGE UHF Wireless Antenna Distribution System, consider the following:

• 신호 없음/신호 약함:
  • Check all cable connections (BNC and power) to ensure they are secure.
  • Verify antenna placement according to the guidelines in Section 4.
  • Adjust the gain settings on the directional antennas. Increase gain if the signal is weak, but avoid excessive gain which can lead to overload.
  • Ensure there are no large metal obstructions or strong interference sources between the antennas and transmitters.
• 간섭/연결 끊김:
  • Ensure antennas are positioned to reject RF signals outside the coverage area.
  • 주변에 유사한 주파수 대역에서 작동하는 다른 무선 기기가 있는지 확인하십시오.
  • Adjust the frequency channels on your wireless microphone system if possible.
• 전원 문제:
  • Confirm the power supply is correctly connected and plugged into a working outlet.
  • Check the DC power lines to receivers for proper connection.
