WIRELESS MICROPHONE/D17-UHF
The D17-UHF typically refers to a UHF (Ultra High Frequency) wireless handheld microphone system. These systems are designed to provide stable, clear audio transmission over a dedicated radio frequency band, offering better sound quality and less interference than older VHF or basic 2.4GHz systems, especially for longer distances.
-
UHF Reliability: Operates in the UHF frequency band (e.g., 600-900 MHz), which is less congested than other bands, providing stable signal transmission and minimizing dropouts.
-
Form Factor: Usually a handheld dynamic microphone, which is rugged, easy to use, and ideal for vocal performances, public speaking, and karaoke.
-
Simple Setup: Most models in this category feature plug-and-play operation with automatic frequency pairing (FM/IR sync) between the microphone and receiver for hassle-free use.
-
Compatibility: The receiver often features a standard 6.35mm (1/4 inch) output plug for direct connection to PA systems, karaoke machines, audio mixers, and amplifiers.
