Hello guys, In this post, I made a Preamplifier Booster for the power amplifier, which can deliver up to 2 Watt RMS per channel. This is a stereo preamplifier booster, so you can easily use this preamplifier booster for dual-channel power amplifiers. For outdoor use, you can not drive your power amplifier by a normal gain output preamplifier. It needs a high-gain output preamplifier, so this preamplifier booster is perfectly tuned for outdoor use. And it helps you to give full power of amplifier.
