使用注意事項

1. 警告: Please connect only one of 110~240V and 28V on the transmitter. Please connect only one of 110~240V and 12V on the receiver.
2. 該 DC power supply of the transmitter is 28V, 4一個, and the receiver is powered by 12V.
3. 該 power switch on the front panel of the transmitter controls 110-240V AC. The DC power supply of the transmitter rear panel is connected to the car battery or battery for direct power supply. (28VDC has no power switch control)
4. The 110-240V and 28V of the transmitter cannot be powered at the same time, choose one of them.
5. A1/A2 on the front panel of the transmitter switches the front microphone input or the rear panel microphone input. Pressing the button is the microphone audio input of the front panel of the transmitter, connected to the built-in amplifier. For non-powered microphones.
6. Press A1/A2 on the front panel of the transmitter again for the microphone audio input of the rear panel of the transmitter, not connected to the built-in amplifier board. Suitable for powered microphones.
7. V1/V2 on the front panel of the transmitter switches audio or audio + 視頻輸入. The transmitter CVBS has video transmission, and if you press it again, there is no video input, the video displays a white screen, and only sound is transmitted.
8. Because the microphone is mono, the microphone on the transmitter is used for right channel input by default, and the receiver audio output must also be connected to the right channel output. If your microphone is connected to the left channel, then the receiver also needs to be connected to the left channel audio output.
9. 發射器前面板音頻輸入和後面板音頻輸入不能同時使用.
