Digital Audio UHF Wireless System

  DWM223

 Digital Wireless Microphone 

  

    

       4th Generation Digital  Audio UHF Wireless Tech


Application Scenarios


1. Pick up and forward sounds from various sound sources on stage (instruments, harmony, chorus);

2. High-end meeting scene.


Characteristics


▪ Based on "DT220 TECH" digital U-segment wireless audio technology, it features stage studio-level sound quality, anti-interference, anti-crosstalk, high fidelity, high signal-to-noise ratio, low noise floor, and excellent wireless transmission distance.

▪ Digital U-segment technology, the effective wireless transmission distance is up to 70 meters, effectively avoiding intermodulation interference.

▪ Ultra-low power consumption, battery life >7 hours (lithium battery), standby time >20 hours.

▪ Using "hybrid power" patented technology, it can be powered by 3.7V 14500 lithium battery or 1.5V AAA AA battery.

▪ Used with a receiver with built-in lithium battery, it can be easily used outdoors.

Common Problems


1. When using a rechargeable lithium battery with poor performance, its voltage reduction circuit will interfere with the performance of the receiver.

2. When multiple sets of equipment are used at the same time, if the frequency point is set improperly, it is easy to cause performance degradation due to intermodulation interference.


Notes


  1. This model of product is recommended to be used with the iweex® brand, the same technology platform, and the model is DTR22X ("X" is any number) receiver device.

  2. Please use batteries from regular manufacturers with qualified products! Counterfeit batteries may cause leakage or even explosion. If any abnormality is found in the battery, please stop the equipment immediately and replace it to avoid the risk of explosion or damage to the equipment!
