hii everyone..!!
here is a circuit degisn from BIASCOMMS which i have attached with the post.. Its a simplest stereo encoder..!
however, i do not understand the use and functioning of the first half of this ckt (shown in the attachment).. Its the design part in which Left and Right speaker inputs are fed to a TL072 dual opamp and the o/p again is Left and Right..!
cant i directly feed the orginal left, right stereo to two individual isolation opamps with preemphasied...??
if anyone knows please advice.. i have found similar type of design parts in many of the stereo encoder ckts. available on the net.. None of them could explain that part...
If anyone knows, please respond..!!
