Wisycom MPR50-IFB

The Wisycom MPR50-IFB is a compact, belt-pack style true-diversity receiver designed for IFB applications.

True-Diversity Reliability This receiver features a real true diversity configuration along with a unique wide-band tuning range up to 232MHz (470-798MHz range), so each receiver can be used anywhere.

Multi-Companding Precisely handling the second part of the companding process, the MPR50-IFB accurately expands the delivered audio signal with Wisycom’s proprietary ENR or ENC companding algorithm with separate release/ attack.

  • ENR (Wisycom Extended-NR)
  • noise optimized
  • ENC (Wisycom Extended-NC) voice
  • optimized & reduced pre-emphasys
  • ENS sound optimized
  • IFB (ENR-Narrow band)
  • IFB-ENS (ENS-Narrow band)

Audio Headroom Expanded audio program material is delivered with our specially designed headphone amplifier designed to maximize headroom with peak-dynamic of +23 dBm (200mW).

Batteries Designed for flexibility to fit the unique needs of stage productions, the MPR50 accommodates several battery configurations by allowing the use of disposable and rechargeable batteries including:

  • Up to 9.5 hours with NI-MH Eneloop Pro NiMh
  • Up to 9 hours with Li-thium Klic-8000
  • Up to 7 hours with Alkaline Energizer

Other Features:

  • Onboard charging via integrated micro-usb-B connector.
  • Easy to use thanks to an OLED display
  • Dedicated function buttons & TX/RX frequency sync function
  • Automatic receiver programming with RX Manager application and micro-USB cable or infrared via optional UPKmini
  • FM IFB mode with NARROW-BAND modulation to enhance noise immunity and coverage (SW selectable)
