Mipro MRM 70B

A Module Designed to Complement a Modular UHF Setup

This receiver module adopts a modular approach: it plugs directly into compatible solutions to add a UHF wireless microphone link without multiplying external units. Its positioning is clear: to offer a clean integration, quick deployment, and consistency with field use (accessible settings, level indicators, metal chassis), while remaining simple to configure thanks to preprogrammed channels and automatic synchronization.

Who Is It For and What Are Its Uses?

This receiver is aimed at users who need a reliable and fast solution for voice: hosts, speakers, educational institutions, associations, light service providers, or musicians using compatible portable sound systems. It is particularly suitable for situations where multiple wireless microphones must be managed (multiple speakers, panel, event) while maintaining clear level control and locking settings to avoid handling errors.

Key Features: RF Stability, Simple Settings, and Field Integration

SCAN: Quick Identification of a "Free" Frequency

The SCAN function allows searching for an available frequency among 16 preprogrammed channels and then locking it. This is a major advantage when the radio environment is crowded: it saves setup time and reduces interference risks without requiring complex adjustments.

ACT: Synchronization and Link Locking

The ACT function ensures calibration and automatic locking of the preset frequency with the compatible transmitter. The result: a faster, cleaner, and more secure transmitter/receiver pairing, especially useful when multiple systems need to be deployed at the same event.

Level Control and Immediate Reading

The module features volume control and sensitivity adjustment to adapt the output level and dynamics to the microphone used and the situation (projected voice, close speech, etc.). The LEDs and indicators facilitate monitoring of AF (audio) and RF (radio) levels, as well as the battery wear status on the transmitter side, to anticipate signal loss and dropouts.

Dual-Circuit Squelch: Reduction of Unwanted Noise

The dual-circuit squelch (Dual Pilotone and NoiseLock ) aims for effective suppression of unwanted noise when the RF signal is insufficient or disturbed. This background noise management is essential to maintain clean broadcasting, especially on a portable sound system used near the audience.

Construction and RF Technology

The UHF / PLL synthesized frequency synthesis technology, combined with a metal chassis, meets the demands of regular use: stability, robustness, and better resistance to handling and transport. The digital display screen (with a 1-digit display indicated) allows for simple and quick reading of useful information.
