96 adjustable channel, automatic selection. TheInfrared frequency can assurethatsignal transmit and receive with no distractions. Using PLL phase-locked loopfrequency synthesis technology, and CPUcontrol. Dynamic LCD display, can display frequency and channel, etc. Usingaudio compression extension technology, which brings a wider frequencyresponse, and lower distortion. We equip the receiver with squelchcircuit, there is no impact on the switch. Two balanceindependent output signals and one non-balance signal output. This system has more flexibility and superior performance. Witha light touch power switch, unique circuit design in the industry, and Power-off memory function. It can show you the clear voice, suitable for Medium stage, school, square and other places.
