6 / 19 page TSH512 6/19 MULTIMEDIA APPLICATION: HEADSET SIDE The TSH512 is used in mono to transmit the signal of the Electret Condenser Microphone of the headset. The circuit is supplied by batteries and the VOX function switches off the output stages to spare energy. The usual working frequency is 1.7 MHz for infrared mono operation. MULTIMEDIA APPLICATION: COMPUTER SIDE In multimedia application, the TSH512 transmits the HiFi stereo from the PC to the headset. TSH512 LNA + ALC LNA + ALC MIC. BIAS MIC.
