Questions Frequently Asked 


1. If there is no signal output when connecting the condenser microphone, please check if the phantom power supply is selected.

2. When charging lithium batteries with poor performance, their step-down circuit will interfere with the performance of the receiver.

3. When multiple devices are used simultaneously, improper frequency setting can easily lead to performance degradation due to intermodulation interference.

4. Some brands of MIC may cause interference due to poor signal shielding, which can be solved by using Cannon extension tubes.

Notes


  1. This model of product is recommended to be used in conjunction with iweex ® Unpredictable ® Brand, same technology platform, model DTR22X ("X" is any number) receiver device.

  2. Please use a legitimate and qualified product battery! Fake and inferior batteries may cause leakage or even explosions. If any abnormalities are found in the battery, please stop the equipment immediately and replace it to avoid the risk of explosion or equipment damage!
