이미지 2: 뒤쪽 view of the XTUGA EW240 receiver. This image displays the back panel of the receiver, highlighting the individual 1/4-inch audio outputs (OUT A, OUT B, OUT C, OUT D), a mixed 1/4-inch output, antenna connections (ANT A, ANT B, ANT C, ANT D), and the DC power input.
- 수신기를 배치하십시오: Place the receiver unit in a central location, away from large metal objects or other electronic devices that may cause interference. Ensure the antennas are fully extended and positioned vertically for optimal signal reception.
- 전원 연결: Connect the provided AC power adapter to the DC 16V input on the rear of the receiver. Plug the adapter into a suitable power outlet.
- 오디오 출력 연결:
- For a mixed output of all four channels, connect a 1/4-inch audio cable from the "MIXED" output on the receiver to the input of your mixer or amp리퍼.
- For individual channel control, connect 1/4-inch audio cables from "OUT A", "OUT B", "OUT C", and "OUT D" to separate inputs on your mixer or amp리퍼.

- 배터리 설치: Open the battery compartment of each bodypack transmitter. Insert two 1.5V AA batteries, ensuring correct polarity. Close the compartment securely.
- 마이크 연결: Plug the 3.5mm connector of either a headset microphone or a lavalier microphone into the input jack on the top of the bodypack transmitter. Ensure the connection is firm.
- 보안 전송기: Attach the bodypack transmitter to clothing or a belt using the integrated clip. Position the microphone appropriately for the user (e.g., lavalier clipped to clothing, headset worn on head).
5. 사용 설명서
- 수신기 전원 켜기: Press the power button on the front panel of the receiver. The display screens should illuminate, showing the channel frequencies.
- 송신기 전원 켜기: Slide the power switch on each bodypack transmitter to the "ON" position. The transmitter's display should light up, indicating its operating channel and battery status.
- 주파수 동기화: The EW240 system is designed for automatic frequency synchronization. Ensure the transmitter and receiver are on the same channel frequency. If channels are not synchronized, refer to the troubleshooting section or consult the full product manual for specific pairing instructions (not detailed in provided data).
- 볼륨 조절: Slowly increase the master volume on your mixer/amplifier and then adjust the individual channel volume controls on the receiver to achieve the desired audio level. Speak into the microphone to test the sound.
- 모니터 성능: Observe the signal indicators on the receiver to ensure a strong and stable connection.
- 전원 끄기 : After use, first turn off all bodypack transmitters, then power off the receiver.
6. 유지관리
- 배터리 교체: Replace transmitter batteries when the low battery indicator appears or when audio quality degrades. Always use fresh 1.5V AA batteries.
- 청소: Clean the receiver and transmitters with a soft, dry cloth. Do not use liquid cleaners or solvents.
- 저장: When not in use for extended periods, remove batteries from transmitters and store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
