Quick Introduction to Frequency Matching

To make your wireless system work normally, the wireless handheld microphones and the power amplifier must be set to the same operating frequency.
Main Unit Settings

• The general setup method is that the main unit and microphones are kept within sight and the antenna is placed vertically.
• Connect the power cord to the main unit and turn on the panel power switch.
• Use standard speaker binding posts to connect the outputs  of the main unit to passive speakers.
• In the main interface, press the MIC A/MIC B button to enter the microphone receiver setting screen, rotate the encoder to change the frequency, and press the SYNC  button to set the frequency.

Wireless Handheld Microphone Settings

• Insert two AA batteries into the wireless microphone and press the power button to turn it on.

• The emitting window on the front panel of the main unit should be placed opposite to the infrared receiving window on the wireless microphone, and the distance should be kept at 15-30 cm.

• When the microphone is pairing with the main unit, the progress bar on the main unit screen will flash, and the wireless microphone screen will light up. When the channel on the wireless microphone screen is the same as that on the main unit screen, the pairing is successful.

• Long press the EDIT encoder on the panel to return to the main interface, or wait 10 seconds  Level Settings:

• When speaking or singing into the microphone, or using the microphone to connect to an instrument, it is at a normal level. Slowly adjust the volume of the panel to reach the level you want.

• If you find that the system shows frequency interruption or burst noise, it may be due to interference from other frequencies. Please follow the steps above to change the channel of the system, or check whether the antenna is installed correctly.
