2 IRA 568 Infrared Column Soundfield System SSS a sincere concern for user Secure A solution to against eavesdrop, LINKX provides other alternative to RadioFrequency system, an ideal solution to secure private conversation and content against interception. Safe Interference worry free. free. Because Because infrared infrared does does not have not have the penetrability, the the user the user does does not need not need to worry to worry outside outside frequency frequency disturbance, and the speech will not be interrupted by external signal created. Sanitation The user may have his own microphone and may carry freely to other room which has LINKX infrared system installed. Eliminate the worry of hygienic concealed when using public microphone.
