PRORECK UK-4000 Microphone System
Need a reliable 4-channel UHF wireless microphone system for karaoke, parties, churches, conferences, or speeches? The PRORECK UK-4000 includes four handheld microphones and a true 4-channel receiver, so multiple speakers can use microphones at the same time.
With 500 selectable frequencies (4 × 125), you can quickly switch to a cleaner channel to reduce interference. It supports an operating range of up to 100m / 328ft in line-of-sight conditions, giving you more freedom on stage or in a room.
For easy integration, UK-4000 provides 4 XLR outputs (one per channel) plus a 1/4" (6.35mm) MIX OUT, making it simple to connect to a mixer, amplifier, or powered speaker. A large LCD display with AF/RF indicators and independent volume knobs helps you set levels fast.
UHF Frequency Groups:
To reduce interference in busy environments, spread microphones across different groups/channels when possible.
