PREMIUM WIRELESS PERFORMANCE: 4 channel UHF wireless microphone system with selectable frequency. Channel 1: 538.3 - 550Mhz (40 channels). Channel 2: 554.8 - 566.5MHz. Channel 3: 571.3 - 583MHz. Channel 4: 587.8 - 599.5MHz. Employs PLL frequency synthesized technology to provide hassle-free sound transmission, minimum dropouts, and maximum feedback rejection. Smooth and quick IR synchronization. Long range operation of 290ft – 328ft line of sight.
STURDY BUILD, MULTICHANNEL MULTISET FEATURE: Sturdy metal builds for the wireless receiver and cordless mic. The cardioid dynamic cartridge is engineered for clear robust optimal true sound. The multichannel feature enables users to select different frequencies when preset frequency fails, thus ensuring interference-free reliable performance. In a total of 4x40 channels, allowing up to 40 systems to be used at the same time. Ideal for church, wedding, karaoke, DJ gigs, public speaking, etc.
AUTO SCAN FEATURE AND ANTI-INTERFERENCE FEATURE: UHF microphone system equips with auto scan function, which enables the system to search for the least interference channel to pair up with transmitters. It also has one 1/4’’ mixed output and 4 XLR separate outputs. 4 antennas design increases anti-interference abilit....
