Dual-Channel UHF Wireless Microphone System

The Gemini MWU-20-2H provides two handheld dynamic microphones operating on UHF frequencies between 530 and 580 MHz. It is designed for singers, speakers and event hosts who need cordless freedom at karaoke nights, church services, weddings or DJ sets. Each microphone weighs approximately 1.928 kilograms including batteries.

Battery-Powered Operation and Mute Control

Handheld units run on replaceable AA cells so there is no charging downtime between events. A single tap on the power button mutes the capsule instantly while a long press on the UP button locks the controls against accidental changes. The cardioid polar pattern rejects off-axis noise for cleaner vocal pickup.

260-Foot Range with 2x100 Selectable Frequencies

The system delivers reliable transmission up to 260 feet thanks to an advanced UHF analog chip and anti-interference antennas. Auto-Scan finds the clearest channel automatically and IR sync pairs transmitter to receiver in seconds. Two hundred total frequencies across the two channels allow multiple systems to run side by side without conflict.

Questions about this item

How do I pair the two handheld microphones to the receiver using the IR sync feature?

Power on the receiver, then each microphone. Hold the mic's IR window close to the receiver's IR window and press the sync button; the auto-scan selects one of the 2x100 UHF frequencies between 530 and 580 MHz. The step often missed is keeping the IR windows aligned until the channel display locks.

What ongoing power supply do the microphones need and how often should I expect to change it?

Each handheld mic runs on AA batteries; carry spares for quick swaps during long events. Battery life varies with usage, so replace cells when the low-power indicator appears or audio drops out.

At what distance does the signal become unstable during a full show?

The system is rated for reliable operation up to 260 ft (100 m) with the UHF analog chip and anti-interference antennas; beyond that range dropouts or distortion may appear first under sustained use.
