The Mipro MRM-70 is a wireless diversity receiver module fitted for use with their MA-705, MA-707, MA-808 portable PA systems, MA-909 wireless mixer, and more.  It can also fit other PA amplifiers, mixers, active powers, signal processors and other karaoke players.

NOTE: Please contact your sales representative for more information in regards to adding modules on custom-built MIPRO PA's (eligible models are listed).

UHF band and PLL technology are utilized to avoid the often congested VHF band.  Diversity and advanced circuitry are incorporated to eliminate signal dropouts and random noise interference.

Mipro MRM-70Features:

  • UHF diversity receiver with 16 automatically scanable frequencies with ACT functions
  • Press the "ACT" button to automatically upload the receiver frequency to the transmitter.
  • Once the frequency has been set, the data is stored in memory, meaning that the frequency is set until it is changed by performing the "ACT" functionagain, even after powering off.
  • Bright and easy-to-read LED displays numeric channel and RF & AF strengths
  • Receiver "Sensitivity" level can be sensitivity adjusted to overcome interference
  • Reliable true diversity reception with dual "PiloTone & NoiseLock" circuit prevents interferences
  • Output level and dynamic range accurately pre-adjusted to equal the microphone capsule's sensitivity, thus ensuring optimal performance of the system. (1.5dB tolerance)
  • Modularized design allows easy installation & maintenance
