Can be on the same frequency, 1D code tracking: dedicated for special planes, use the same frequency without interference; “Optional two antennas to receive, or four antennas to enhance the reception of information” [Audio output: MIC: public 6.3 sockets;  independent audio output card

Longkou AB ] panel There are volume up and down adjustments.

Transmitter Microphone: The microphone is divided into A microphone and B microphone: IR ▼ button to select the channel, wireless data is automatically connected to the LED  display, battery display screen, and the ID receiver is automatically connected to the ID receiver within 3 seconds after the microphone is turned on; Receiver …

Transmitter Microphone: Microphones are divided into four microphones A, B, C, and D. Mark: IR ▼ button to select a channel, wireless data automatically uses LED display for up-frequency, battery display screen, automatic scanning and tracking ID code reception within 3 seconds of opening the microphone Connect the receiver to use; select the frequency for 1 second after the microphone is turned on and connect to the receiver …

How to Use Connection

1. Open the package, receive the machine card on the antenna accessories: use the following connections: Voltage DC: 6V-13V/ 500mA
2. Control the volume of the audio equipment to the minimum first; plug in the wireless microphone receiver and connect the audio cable (about 1.2 meters of audio cable,  one end is connected to the socket of the wireless microphone receiver; the other end is connected to the MIC socket of the audio equipment; connected to the power supply and turned on .
3. There is a touch switch under the battery display on the microphone. Press it to turn on the microphone. The microphone has an IR position. The touch switch button is the frequency selection button.
4. When the microphone is turned on, the microphone will be automatically detected within 3 seconds to 5 seconds, and the RF light of the signal connected to the receiver  will be on for a long time
5. Each set of microphones is for the use of locked special-purpose microphones, and can also be used in multiple sets …

UD Lock Code/Code Operation

1. Turn off the receiver first, [press and hold the frequency selection button while the wireless microphone is turned off, and press the switch button again without releasing it]; after the display flashes for about 2 seconds, release the two buttons, and then turn on the power switch of the receiver, at this time, the wireless microphone receiving ”  RF ” indicator on the receiver panel will flash 4 times, and then press the wireless microphone frequency selection key to complete the code pairing; code is successful.
2. After the code is locked/paired, the current wireless microphone and the receiver become a unique pairing, and there will be no crosstalk and interference even if there are multiple identical receivers or machines with the same frequency.

Restore Factory State Operation

When the microphone cannot be connected to the receiver due to misoperation or other reasons, it can be restored to the factory state through the reset setting at this time.
The operation is as follows: the first turn on the power switch of the wireless microphone receiver. In the case of not installing the battery, press the [frequency selection key of the microphone; hold], then 2 seconds after the battery is installed, and release the frequency selection key after 2 seconds; the microphone will be restored to the factory settings.  [The same operation method is used for conferences and lavalier clips …] Later… [Re- operate the ID lock code again]
