This series of products of double frequency lock type 4 channel wireless conference microphone, with less noise interference of UHF frequency band PLL phase locking technology, double lock frequency circuit design, noise interference, any similar system cannot match. All metal material standard chassis, metal panel configuration channel receiver, assembly LCD display screen, display work channel and frequency respectively. Good, quick to understand all the actions of the receiver information. Host respectively with balanced audio output socket, and mixed unbalanced output, comprehensive to meet the needs of all kinds of connections.
