MPR51-ENG is a compact wideband receiver designed for professional ENG, broadcast, and field production applications.
This receiver features a real TRUE DIVERSITY configuration along with a unique wide-band tuning range of 230 MHz of bandwidth.
The software selectable
analogue and digital outputswideband and narrowband DSP-FM operation
gives users options based on their project needs.
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.
