Product Description

MTB40S is an extremely small and light plug-on transmitter especially designed for professional wireless microphone applications.

MTB40S benefit of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.

Improved features:

  • New white OLED display
  • New XLR locking system
  • Integrated HW limiter

Key Features:

  • Up to 232 MHz bandwidth in 470/798 MHz range
  • Enhanced robustness against self-interferences and antenna performances thru a proprietary “intermodulation cancellation” circuit
  • Miniature design with flexible pcb (no connectors) for extended reliability
  • User selectable companding systems:ENR (noise optimized) / ENC (voice optimized)
  • Input dynamic extension with an integrated HW limiter (30 dB above peak)
  • P48 phantom power for condenser microphones
  • New white OLED display (128 x 32 pixels)
  • New XLR-3F connector with locking collar to ensuring an extremely tight noiseless fit!
  • Infrared interface for management and firmware update
  • Audio input circuitry with high linearity audio transformer
  • Battery: 2 AA Alkaline or rechargeable NiMH
Switchable channels 2400 allocated by 40 groups of 60 channels (in specific frequency range), quickly selectable with dedicated buttons
