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. |
