Wisycom MPR50-IEM Wideband IEM Receiver

MPR50 is a compact true diversity receiver designed for professional in-ear monitoring aapplications.

This receiver features a real TRUE DIVERSITY configuration along with a unique wide-band tuning range up to 232 MHz. Audio processing can be Stereo MPX or mono based.

The output audio stage is especially design to have maximum audio peak-dynamic of 200 mWatt.
Very easy and versatile thanks to its Oled display, navigation button controls, infrared and automatic scan.

Battery management is very flexible since MPR50 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 thru the integrated micro-usb-B connector.
