WT-4800 Wireless Tuner

  • WT-4800 Wireless Tuner
  • The WT-4800 Wireless Tuner is designed for use on the UHF band, and suitable for vocal or speech reinforcement applications. It features a compander circuit which minimizes the influence of ambient noise.
  • 64 different operating frequencies (4 banks x 16 channels).
  • Optimized PLL-synthesizer drastically minimizes the oscillation frequency drift resulting from the ambient temperature changes.
  • The Scan function indicates available idle channels and is useful when changing the operating frequency.
  • The LCD screen indicates the current operating frequency, as well as RF and AF levels.
  • Antenna distribution outputs and audio cascade inputs facilitate connection of another unit to build a dual-channel system.
  • Compact size and high reliability
