Hi, You have 2 options: 1. as Moss said use 2 identical optocouplers (in same package) 2. use FM modulation for audio isolation. The common way is to use the 1'st option. If you're searching on HP web site you'll find a good essay regarding optocoupler compensation for nonlinear amplitude response. Hope this help, //a
Hi, We have two channel audio to be seperated from the final stage audio amplifier. Now becase of different products the final power ampifier keeps on changing and we come across gounding loop/ humming noise. I know that optocoupler could be used to eliminate this. Does any one knows any good one for audio (analog). (...)

Here is challenging little problem: I have a circuit (current source) which I want to drive with combination of four independent analog signals. Sources of signals will be sound cards. The frequencies will be very low - fraction of Hz. Because they are four independent sources I want to isolate the signals. I want to use optocouplers. I wan
It will be better if describe your project more in deep. 1. Mic. is not out it is IN 2. RCA jack - is audio connector type, looks like stick with 2 0r 3 contacts 3. RCA jack recorder - I don't know what is it :( 4. Input impedance of mic. input vary for different microphone types, from 15k to more then 100Meg , what mic you intend
and ofcourse the mechanical data and pin configuration for ur pcb design, well if u get an unknown transistor how do u kno what is the application for tat, i mean other hat general purpose trans most of them are optimized for various appications like rf, audio, etc and in comarision sheet u also can get alternatives. more over wen a transistor is
circuitry without physical realisation is hard to make and especially for that in your case i would be needing the output level of the audio system that drives the optocoupler and also the input levels of the MOSFET,... also if a fault occurs it would be hard for you or me to correct.... you post your proceedings in the circuit and i'll let u k
Hi all, I need an audio limiter/compressor using a FET optocoupler like H11F1M or H11F2M or even H11F3M. This is to be used as a ham mic audio processor. Regards, Fernando
