WEISRE PGX - 58 PROFESSIONAL UHF DUAL WIRELESS MICROPHONE MIC SYSTEM FOR KARAOKE PARTY KTV

Main Features:
- Wireless microphone brings you unconstrained happiness
- Using 170 - 790 MHz frequency to avoid the interference
- Using multilevel high frequency narrow band filter, so as to dispel any possible interference signals
- Using special ALC circuit to avoid losing your own sound due to big volume
- With the low consumption components, the life of the battery will be much longer
- With the power indicator circuit in the hand-held microphone, so you will know when to replace the battery
- With the decreasing back-put whistle function, it can decrease the whistle efficiently
- Power supply: One microphone is powered by 1 x 9V battery ( not included）
