PTU-51/5000/4000 Wireless Microphone System

Phenyx Pro introduced the PTU-5000, a UHF fixed-frequency quad-channel wireless microphone system, in 2018, and it immediately gained tremendous popularity with its plug-and-go operation and clean sound quality. Soon we launched the dual-channel (PTU-51) and eight-channel (PTU-4000) versions to complete this fixed-channel cordless microphone system series.

/ Overview



The biggest complaint with wired microphones is that they can cause clutter and tripping hazards and are hard to rearrange. So Phenyx Pro has developed a series of wireless microphone systems at an affordable price for public speakers, lead singers, professional hosts, and anyone else who is ready to step out from behind a rostrum. The PTU-51 (dual-channel), PTU-5000 (quad-channel), and PTU-4000 (eight-channel) systems build up the entry-level wireless microphone series that offers a perfect solution to solve the problem of traditional microphone cables. With straightforward plug-and-go operation from the fixed-frequency design and the loud and clear sound quality, this go-to simple and accessible audio solution brings your audio to live. Hook it up. Make yourself heard!
