MTP41S

Wideband Bodypack Transmitter

MTP41S 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. MTP41S benefit also of the latest Wisycom RF technology along with an enhanced robustness against noise.

Improved features:
– Integrated HW limiter

FEATURES

  • Up to 232 MHz bandwidth in 470/798 MHz range (others on request)
