Wisycom MPR52-ENG

MPR52-ENG is a compact two channels receiver designed for professional ENG applications. The new MPR52 has two built-in diversity receivers with both analog and digital outputs. With up to 790 MHz bandwidth in the 470/1260 MHz range, the MPR52 features next generation multi-band front-end filtering.

The software selectable wideband and narrowband DSP-FM operation gives users options based on their project needs. Country-specific Surface Acoustic Wave (SAW) filters are also available (USA: 935-960 MHz and Japan: 1240-1260 MHz).

The receiver also offers convenient function buttons, including a dedicated frequency scan option. Battery management is flexible as it features standard battery packs that can be charged with the dedicated charger or through the micro-USB-B connector.
