Lapho i-voltage ingezwa kwi-Electro-Optic Crystal, inkomba eyeqanayo nezinye izakhiwo zoshintsho lwe-crystal, shintsha isimo se-polarization segagasi elikhanyayo, bese likhanya ngokukhanyayo liba yi-polarizer e-polarizer, futhi amandla okukhanya alungisiwe. Ngalesi sikhathi, igagasi elikhanyayo liqukethe imininingwane yomsindo futhi lisakaze endaweni yamahhala. I-PhotoDetor isetshenziselwa ukuthola isibonakaliso sokukhanya esinqunyelwe endaweni etholayo, bese kuthi ukuguqulwa kwesekethe kwenziwa ukuguqula isiginali ye-Optical ibe yisiginali kagesi. Isiginali ye-Sound ibuyiselwa yi-demodulator, futhi ekugcineni ukuhanjiswa kokukhanya kwesiginali yomsindo sekuqediwe. I-Voltage esetshenzisiwe yisiginali yomsindo odluliselwe, engaba ngumphumela werekhoda yomsakazo noma i-tape drive, futhi empeleni isibonakaliso se-voltage ehlukahluka ngokuhamba kwesikhathi.
