GTDaudio 2x800 UHF True Diversity Wireless Handheld Microphone System

Our review of the GTDaudio 2x800 wireless handheld microphone system finds it best suited to small venues, churches, DJs and karaoke hosts who need reliable reception and a large selection of selectable channels. The single biggest reason to buy is the combination of true diversity reception and 800 selectable channels, which together reduce dropouts and let multiple systems run in the same space. It is a practical, budget-conscious pick for events where steady signal and easy setup matter more than premium styling.

Key Features

• True diversity operation: Provides improved reception and fewer dropouts by using two independent receivers to choose the best signal automatically.
• 800 selectable frequencies: Offers up to 2 x 400 frequencies across channels so multiple systems can coexist without interference.
• Automatic frequency scanning: Finds and sets an interference-free channel in the area to simplify setup in crowded RF environments.
• Automatic transmitter setup: Synchronizes the handheld mic to the receiver quickly, speeding deployment at events.
• Long range capability: Provides usable operation up to 400 ft (120 m), suitable for medium-sized venues and outdoor gatherings.
• Tone Lock squelch circuit: Helps cut unwanted noise when no valid signal is present, which keeps background hiss lower between uses.

Who It's For

The GTDaudio 2x800 is aimed at churches, DJs, karaoke hosts and small event managers who need a dependable wireless handheld solution without a high price tag. Its broad frequency options and true diversity reception make it a good match for setups where several wireless systems may be used at once or where sources move around a stage or room.

Those who should look elsewhere include users requiring professional broadcast-level features, metal chassis rackmount builds, or proprietary branded ecosystem accessories; also consider higher-end systems if you need stronger RF performance in extremely congested urban frequency bands.
