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.

• Balanced XLR & 1/4" phone audio outputs.

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