  Eight-Channel Digital UHF Wireless Receiver 

  

 

  *GAODIMIC®  Products of the same brand and model are consistent with this product.

   

       4th Generation Tech Platform


Application Scenarios


1. In large-scale performance sound projects, replace the cable of wired microphone;

2. Used for pickup and forwarding of various sound sources (instruments, harmony, chorus) on stage;

3. Conference speech pickup and forwarding.

Characteristic


1. Within the full sound range of 20-20KHz, the frequency response attenuation is <2dB, and the phase response characteristics are controlled between +30°~-60°;

2. Latency is less than 4ms, stage performance level;

3. In ordinary wireless environment, the maximum transmission distance can reach 100M without frequency interruption;

4. Signal-to-noise ratio >96dB, greatly improving noise control capabilities;

5. Excellent concurrency capability, supporting up to 40 transmitting devices working at the same time.
