Each input and output is protected from ground short-circuit. The 75Ω output is protected through a 75Ω resistor. Audio Switching Two electronically switched inputs : - 300mV rms input coming from internal audio. - 100mV rms input coming from the peri-TV plug one low impedance output 300mVRMS. APPLICATION CIRCUIT Inputs and outputs are also protected against ground short-circuit. Switching Logic The logic takes into account the informations on 3 pins. - Internal or external video and sound (.
