Product Description
PM-320 is a wireless monitoring system for stage performances and audio broadcasting, and a wireless listening system for large simultaneous interpretation conferences. High-fidelity sound, advanced electronic processing technology instead of the traditional complicated and heavy monitoring equipment, eliminate the howling from the monitoring equipment, and make the performance reliable and perfect.
Performance Introduction
International EIA standard chassis
1/2 EIA standard 1U chassis made of metal
UHF wireless receiving frequency band
The receiver adopts the UHF frequency band, and the CPU controls the diversity reception to reduce dead spots and ensure stable reception.
long distance audio transmission
It has a long transmission distance and is suitable for various occasions.
audio monitoring
Has a headphone monitor output.
Ultra Wide Spread Spectrum
The bandwidth is 32MHz, with 1280 adjustable frequencies. Channel groups 1-10 are factory preset with up to 180 fixed frequencies. Channel groups U1-U5 can freely set and save frequencies.
PLL phase locked oscillation circuit
Stable PLL phase-locked oscillator circuit, combined with the "noise detection" mute control function, can effectively block the noise and radio frequency interference in the working environment.
