Sound to light controller circuit the S2L unit gets its communication signal processing input from a ¼ inch jack plug. This then goes into optical isolator Semiconductor an opt coupler. The optical isolator provides an isolation for the signal wave input to the integrated circuit of the printed circuit board. A common optical isolator is a MB111 WFX 1988. But you will have to get the right maching semiconductor for your interactive switching device controller or an equivalent value Semiconductor if your does blow. Photo coupler isolator is a simple circuit that provides the logic pulse to drive the frequency to light 3 way switch light or 4 ways switching light controller. It will convert sound to light pulsars that gives a TTL or CMOS Logic. The sensitivity to S2L unit is regulatory by a variable resistor. After all Logic processing has finished, it will drive a Triac, have a look on your schematics circuit output and you will see a Triac Semiconductor or a (SCR) Silicon Controlled Rectifier.

If your S2L controller has stop chasing or flashing to the sound it will be the optical isolator that has blown but if only one channel that does not come on its more likely to be the Triac. There are many to cheap project circuit kits that can be purchased for making led sound to light any of these will drive an opt coupler. So to cheap equipment is very possible just a degree in electronics is required. If you’re going to run a dee jay mobile show, it’s really worth while doing a short course in electronics. So your audiovisual equipment rental at the dichroic beam diagrama event will not look a sham whilst you rent space age equipment out to the lovely general public.
Hello, what is the number of the IC used in the power circuit of Yamaha MG24/14fx console mixer. Or which IC can be used to replace the faulty IC
