Debra UX-400 UHF 4-channel wireless handheld microphone, rechargeable microphone, 80M transmission distance, for stage, karaoke

Product introduction:

This wireless microphone uses UHF signal transmission. Handheld microphone transmitter and receiver are made of metal. Redesigned circuits and high-quality chips optimize sound signal transmission, greatly reducing sound loss in wireless transmission. The stable transmission range of the system is 80m, which can reach 100m in open areas and without signal interference. The multi-function receiver has a built-in SYNC automatic frequency search function, which can automatically search and locate safe frequencies in complex environments to avoid signal interference. The transmitter pairs quickly via infrared matching. The sound reproduction of this wireless microphone is very high, making it ideal for family gatherings for singing, conference speeches, and even stage performances.

Features:

● Both the transmitter and receiver use high-definition LCD screens to display detailed information including power supply.
● The built-in chip of the receiver has a metal signal shield, which has better anti-interference ability.
● The microphone has a built-in lithium battery that can be recharged through the TypeC interface. The battery life is 5-7 hours.
● Using high-quality microphone chip, good sensitivity, clear and high-pitched sound.
● The wireless signal range can reach 80m, and can reach 100m in an open and interference-free environment.
● Built-in SYNC automatic frequency search function, a safer signal environment for use in complex environments.
● The receiver has four antennas, making signal reception more stable.
● Each channel has built-in 50 switchable frequencies and IR frequency matching.
