Product Details

Audio Professional wireless tudio microphone mic system BNT780U

One-for-two wireless microphone (standard: seat microphone, optional: handheld, pocket)

Function

● Adopt the world's most advanced DPLL digital phase-locked loop multi-channel frequency synthesis technology and noise automatic control technology (with pilot).
● UHF640MHz ~ 690MHz frequency band is used to avoid interference frequency.
● New energy-saving mode setting, full-automatic EQ control function, automatic tone correction, full-automatic on-off mode, automatic infrared frequency-matching system, and full-automatic scanning.
● Dual microphone design, two people can sing invisible antenna of handheld microphone at the same time.
● Using a true diversity receiving circuit design to ensure continuous speed within the effective distance and eliminate dead angles.
● Using the latest high-frequency surface acoustic filter to filter out out-of-band interference signals to the greatest extent.
● High frequency circuit design with secondary frequency conversion, with extremely high sensitivity.
● Speech compression and expansion circuit, which greatly improves the signal-to-noise ratio. The unique design of the voice limiter allows singers to sing hard without cracking.
● Using high-gain antenna, it can effectively open a complete input and output interface with a distance of up to 100 meters, which is convenient for connecting various equipment.
● Any microphone in this system and any receiver can be up-frequency, which completely solves the shortcomings of fixed frequency microphones and is suitable for multiple sets of products to be used on the same occasion.
● Optional: TDWJ1 lavalier microphone or TDWJ2 headset microphone.
