![]() Please suggest me a good quality stereo audio small signal preamplifier circuit which can work from 5 or 6 volts single supply, that would not load the set top box, preferably using good low noise op-amp with detailed circuit and parts label.Ī simple pre-amplifier circuit can be very easily built by assembling a couple of transistors and some resistors as shown in the following figure:.I think the audio signal level from set top box is not sufficient for the FM module. But when I connect the same through audio input jack from DTH set top box the signal strength becomes weak even with full volume in both set top box and FM module. The module works great in computer USB mode with great signal strength, quality and coverage.I have a FM transmitter module which works on 5 volts DC with provision to connect from Computer through USB or from audio out from any other device through 3.5 mm audio jack.Often I will be browsing your website and found many useful projects. Electronics is my hobby since so many years.The first idea is based on the request presented by Mr. The post explains 5 preamplifier circuits which can be quickly made using a couple of transistors (BJTs) and a few resistors.
