Question about LogiSys SP6006CL Clear 2.1+1 Multimedia Clear Speaker w/ Blue LED - RETAIL Computer Speakers
I would like to increase the sensitivity of my speakers. Their sensitivity is set at 300mV and that is way too loud for my use. I have to have the volume turned too high for my small space, so I think I need to increase the sensitivity so they will light up at a lower volume. (the lights are the reason I chose these speakers in the first place!) The speaker sound is fine at lower volumes, but I can't get the lights. Help! Thanks! :)
Hi, am afraid the only way this could be done is going inside the enclosure and modify the circuitry of the light activating section. If you are comfortable working with soldering iron, testers and printed circuit board (pcbs) then you might have a go for it. Simply add a preamp in between the sensor and trigger (or amp) for the light. Other than the input and output of the pre-amp, only the + and gnd leads need to be connected. Get one of those preamps from RadioShack or hardwire one using LM741. Just make sure the B+ is roughly the same. You may want to add a trimpot to be able to adjsut sensitivity. But then again, there might already be a trimpot (variable resistor) adjustable for this purpose. You still have to open it up and look for it. It should be near the frontend (sensor) of the light trigger no the ouput. If you're not too comfortable with any of the above, you probably should seek the help of an electronics technician capable of component level work. Hope this be of some help and good luck.
