MTP40S

Wideband Bodypack Transmitter

MTP40S is an extremely small and light pocket transmitter especially designed for professional wireless microphone applications. Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector. MTP40S benefit also of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.

Improved features:
– New white OLED display (128 x 32 pixels)
– Integrated HW limiter

FEATURES

  • Up to 193 MHz bandwidth in 470/663 MHz range (others on request)
  • Input dynamic extension with an integrated HW limiter (30 dB above peak)
  • Enhanced robustness against self-interferences and antenna performances thru a proprietary “intermodulation cancellation” circuit
  • Miniature design with flexible pcb (no connectors) for extended reliability
  • Ultra-light metal alloy body (80g without batteries)
  • User selectable multi-companding systems:
    ENR (noise optimized)
    ENC (voice optimized)
  • Battery: 2 AA Alkaline, rechargeable NiMH or Lithium
  • Autonomy:
    > 7h @ 100mW output power
    > 10h @ 50mW output power
    > 14h @ 10mW output power
  • Infrared interface for management and firmware update
  • Easy and quick to setup thru an Oled display gain/freq button and a joggle selector
  • Extended regulation on Mic input gain: 85dB in 1dB step
  • Max input level 26dBu (15.5 V clipping) to connect directly to mixers and instruments
  • 48V phantom power to use wired mic thru the PHA48 accessory
