The new VM-99u wireless microphone is the first generation of UHF wireless microphone system designed by the engineering team of Better Music Builder.
VM-99u is designed for both commercial and public use. It is a heavy duty design including one hand-held microphone with one receiver. Each hand-held microphone has a total of 16 frequencies. We have set up 16 frequencies for each microphone to make the frequency selection easily. This system is reliable for use by KTV clubs, restaurants, coffee shops and churches, etc.
Features:
- The working frequency range: UHF520~810MHZ (tunable)
- CPU control (PLL frequency compose technique)
- Channels: 16 or 100 (optional & tunable)
- True diversity system control by CPU for the advance break up function and control receiving of the right and left channels
- Big LCD (Liquid Crystal Display)
- The transmit and receive audio system is adopted high-pass, low pass & band-pass filter technique to avoid noise and keeps sound quality
