UHF Wireless Lavalier System for Speech

The Nady UHF-3 DigiTRU system operates on a fixed 509.55MHz frequency, delivering hands-free audio for DJs, presentations, houses of worship and karaoke. A bodypack transmitter with mute switch and lavalier microphone connects to a half-rack receiver with diversity reception. It is built for speakers and performers who need cable-free movement.

Fixed-Frequency UHF Operation Limits Flexibility

The single 509.55MHz channel cannot be retuned, so the system works only where that frequency is clear and legally permitted. Crowded RF environments or venues with multiple wireless systems may cause conflicts that a frequency-agile unit would avoid. Buyers who need to coordinate several channels or tour across regions should choose a multi-frequency system instead.

120dB Dynamic Range Defines Audio Quality

Proprietary companding circuitry achieves a 120dB dynamic range, which determines how cleanly the system captures quiet speech and loud vocals without noise or distortion. This single specification tells you whether the wireless link meets professional audio standards for your application.
