Wisycom MTP41S Wideband Bodypack Transmitter - B5 Band 1 (470 to 654 MHz)

Share

The Wisycom MTP41S is an extremely small and lightweight bodypack transmitter especially designed for professional wireless microphone applications. It is very easy to use thanks to an improved OLED display (128 x 32 pixels), dedicated buttons and a joggle selector. The MTP41S includes the latest Wisycom RF technology plus an enhanced robustness against noise and inter-modulation.

Wisycom MTP41S Transmitter - Features:

• Up to 232 MHz bandwidth in 470/798 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 (60g without battery)
• User selectable multi-companding systems:
  ENR (noise-optimized)
  ENC (voice-optimized)
• Battery: 1 AA Alkaline, rechargeable NiMH or Lithium
• Autonomy:
  > 5h @ 50mW output power
  > 7h @ 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: 80 dB in 1 dB step
• Max input level 26 dBu (15.5 V clipping) to connect directly to mixers and instruments

NOTE: This MTP41S transmitter is for the B5 Band 1 (470 to 654 MHz) option and in a Black finish. For a different option, please call to place a special order.
