MC-104 is a one-to-four  wireless conference system.  It adopts UHF
high frequency band transimission and DPLL digital phase-locked loop
mutli-channel frequency synthesis technology to make transmission more reliable
and anti-interference ability stronger. Convenient to use multiple sets of
machines at the same time, easily avoid all kinds of interference. The system is
easy to operate, easy to install, economic and applicable, is a good choice for
conference engineering. MODEL   MC-104 RECEIVER Frequency
