Share

NOTE: Temporarily unavailable due to parts shortage and redesign. Anticipated return: Q1 2025

The Wisycom MPR50-IFB is a compact true diversity receiver designed for professional IFB monitoring applications. This receiver features a real True Diversity configuration along with a unique wide-band tuning range up to 232 MHz.

The receiver is especially designed to have maximum long-lasting battery life and complete compatibility with Wisycom transmitters. Very easy and versatile thanks to its OLED display, navigation button controls, infrared and automatic scan.

Battery management is very flexible since the MPR50-IFB allows use of standard battery pack:
– (2) AA NiMH or Alkaline
– C3-V3 battery pack
– KLIC 8000 or CR-V3R lithium (i.e. DR9708 Duracell)

Charging can be done with dedicated charger or through the integrated micro-usb-B connector.
