PMS 380個人監(jiān)聽系統(tǒng)
The PMS 380 Wireless Personal Monitor System

恒勝PMS 380入耳式個人監(jiān)聽系統(tǒng)提供清晰精確的音頻及強大的射頻性能。 精準(zhǔn)的前端射頻濾波器可有效減少射頻干擾造成的掉頻現(xiàn)象。增強型數(shù)字立體聲編碼器提供優(yōu)異的隔離度和清晰的立體聲效果。
The PMS 380Wireless Personal Monitor System from MICMAS offers an unprecedented combination of superb audio quality,
 Precision front-end RF filtering significantly reduces dropouts from RF interference, and the enhanced digital stereo encoder provides excellent stereo separation and audio clarity.

P3T發(fā)射機功能 

射頻功率開關(guān)實現(xiàn)在系統(tǒng)設(shè)置時不會產(chǎn)生射頻干擾
使用掃描和同步功能通過紅外線輕松快速地實現(xiàn)與P3RA腰包式接收機同步.
.前面板音頻輸入增益調(diào)整、LED電平顯示
環(huán)路輸出接頭提供多個混音設(shè)置且易于安裝
可切換的+4 dBu和-10 dBV輸出電平
前面板1/8英寸頭戴式耳機輸出，方便監(jiān)聽
