Gemini TW620 Wireless Handheld Microphone System

The Gemini TW620 Silver is a 15-channel UHF wireless handheld microphone system designed for live sound applications. It operates in the 902.8-914MHz band with a cardioid polar pattern for feedback suppression. The system includes one microphone transmitter and a rechargeable receiver with a 6.35 mm output jack. It is suited for karaoke, speeches, weddings and small stage performances.

Rugged Metal Build with Plug-and-Play Connectivity

The microphone and receiver feature rugged metal construction for dependable performance and long life. The receiver connects directly to a mixer or powered speaker via its integrated 6.35 mm jack, eliminating the need for extra cables. Automatic frequency syncing pairs the transmitter and receiver instantly on power-up. Fifteen selectable channels allow up to 15 systems to run simultaneously without interference.

Check Power and Input Compatibility Before Buying

The handheld transmitter requires two AA batteries which are not supplied with the system. The rechargeable receiver charges via USB in roughly 2-3 hours and delivers 6-8 hours of operating time. Your mixer, amplifier or active speaker must accept a 6.35 mm jack input to receive the signal. The 200ft line-of-sight range assumes clear conditions; walls or obstacles will reduce the effective distance.

Questions about this item

What UHF frequency band does the TW620 operate on, and how many simultaneous channels can it support?

The system uses the 902.8-914MHz band and provides 15 adjustable channels, allowing up to 15 sets to run at once without interference.

What physical connections does the receiver use to plug into a mixer or speaker?

The receiver has a built-in 6.35 mm jack that inserts directly into a 6.35 mm input on your mixer, PA speaker or amplifier.

How do you pair the handheld transmitter with the rechargeable receiver, and what is the common mistake?

Turn both units on; they sync automatically. The step users miss is installing the two AA batteries (not included) into the handheld mic before powering it up.
