Basic Audio Optocoupler. The circuit shown in Fig. 5.3.4, adapted from a design in Newnes Electronic Circuits Pocket Book by Ray Marston (ISBN 10:1-4832-9192-8) uses the 4N25 connected as a phototransistor to pass audio signals whilst …

audio opto isolator 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). I am ...

crutschow thanks for the diagram and the info I have somewhat of an idea of what you are saying but not totally sure. JDT I actually considered that as modem transformers are what I used in my current interface. However they are to large. To give an idea the case I am using is roughly half the length of an Altoids tin so once I squeeze in the usb ttl board, the usb audio …

The audio output signal appears across RV1 and is DC-decoupled via C2. TRIAC INTERFACING. An ideal application for the optocoupler is that of interfacing the output of a low-voltage control circuit (possible with one side of its power supply grounded) to the input of a triac power-control circuit that is driven from the AC power lines and which ...

Audio: Optokoppler galvanische Trennung (zu alt für eine Antwort) Stefan 2005-05-25 08:46:47 UTC. Permalink. Hallo zusammen, ich benötige hin und wieder kleinere Audioschaltungen (Symmetrieverstärker, Kanalmischer, Vorverstärker, etc.) und baue die meist selbst auf Op-Amp-Basis. Ab und zu ist es nötig, die Audioquellen
Linear Optocoupler Circuit - ElectroSchematics.com
https://www.electroschematics.com/linear-optocoupler-circuit/
This linear optocoupler is built with MOC5010 and can be used to isolate a circuit from main grid, audio interface, in medical electronics and many other applications. Because of its high isolation resistance (10 11 Ω), MOC5010 is used in applications where a circuit is powered directly from main power. With a bandwidth from 5 Hz to 100 kHz ...
Optocouplers for DAC? | diyAudio
https://www.diyaudio.com/community/threads/optocouplers-for-dac.11886/
I intend to completely separate left & right analog and digital circuitry in my DAC, so I need to feed bit clock, data and word clock signals (768kHz word clock) through optocouplers without destroying all my effort for clean and low jitter clock signals. Can anyone recommend a readily...

Psychological border experiences are set down in text and verbally staged via radiophone. Audio documents (interviews) are tonally processed in a radical way that is based on the spatial model of an existential, physical injury. Urban paths, generated by GPS navigation are translated into an instrumental composition for two stringed instruments.
