    MC830 UHF 1 for 4 wireless conference microphones

    UHF band makes fewer interference compared with the conventional VHF band and more reliable transmission;

    DPLL multi-channel and frequency synthesis technology provides up to 200 channel selection within interval of

    250KHZ within the range of 50MHZ and satisfies simultaneous operation of multiple sets and keep away interference;

    The advanced frequency pairing technology automatically locks and adjusts the frequency by only one press if

    the frequencies of the transmitter and the receiver are not paired and operation is convenient;

    High-end LCD makes working status of the receiver and the transmitter clear; the wireless conference transmission

    system is powered by 2 pieces of AA batteries and hi-alkali battery lasts longer.

    The conference desktop, handheld, clip and head-mounting are optional.
