Overview:


MR-823D UHF Dual Channel Diversity Receiver

Key Features


CPU-controlled diversity. "NoiseLock" squelch prevents random noise interference sources like computers, karaoke machines and DVD players.

Ideal for for DJ, Karaoke. Stable, easy to install, most affordable fool-proof unit.

Upgraded receiver panel with easy-to-read displays and user-friendly functions.

First receiver equipped with a balanced volume control to enable users to adjust the mixed output volume of two wireless microphones. 

The system's default output level is accurately pre-adjusted to match the microphone capsule's sensitivity and designed to deliver an optimal performance without over load distortion.

First receiver equipped with a "receiving sensitivity adjustor" on the receiver front panel to allow users to adjust to a higher sensitivity in order to increase receiving distance and to eliminate signal dropouts, or to adjust to a lower sensitivity to avoid noise interference.

First receiver equipped with a "NOISE" LED indicator. Users can first identify whether the receiver is experiencing interference and can then make accurate adjustments in the receiver's sensitivity to eliminate the interference and establish optimal performance.

RF and AF signal indicators to identify if the system is receiving signals properly.
