PROEUROTECH UHF124 ไมค์ลอยตั้งโต๊ะ4ตัว ความถี่ใหม่ที่ กสทช อนุญาติใช้งาน สามารถปรับความถี่ได้ ตัวไมค์ใช้ถ่านแบบ AA 2ก้อน เครื่องรับสามารถติดตั้งในแร็ค19นิ้วมาตราฐานได้ Using UHF wireless microphone special frequency, without interference from other industrial frequency. PLL digital frequency synthesis technology, provides up to 200 selected working channel, realize the simultaneous use of multiple machines. use infrared frequency synchronization technology, the transmitter operation is simple and convenient. In the transmitter power adjustable. When outdoor use, the choice of high power, the use of distance far, in the classroom or KTV oc casions when using low power, can reduce the interference, save battery. In the pilot data control technology, effectively prevent the impact of radio frequency interference and other acoustic trans mitter switch machine. In the transmitter uses 2 1.5V/AA batteries power supply, battery used for a long time, more convenient maintenance. with balanced and unbalanced audio output, convenient connection and various audio equipment. In the receiver can display parameters of the transmitter, which is convenient for monitoring. In the transmitter is made of high strength alloy materials, durable.
