Hello,
Let me first introduce myself. Im Ryan, I have a very basic understanding of electronics but im looking at putting a little project together. The project is a small system to power 4 speakers which are around the house.
The idea is to have 2 small amplifier board powering two speakers each, with a Bluetooth audio receiver linked by a pre-amp.
Now the problem, I purchased a £6 pre amp kit for maplain's (to bot get some practice and as a kind of "proof of concept") all built and working fine apart from a low 1 second "thud" coming from the bass. The thud is considerably louder then the volume of the speakers.
The pre amp is being taken from the line out of a PC to a standard Hi-FI amplifiter and a pair of bookshelf speakers (Again this is just to test and not the final design)
The amp is powered by a 12v 750mA AC-DC converter (Just a spare)
Any ideas why this is occurring?
Apologies if this is in the wrong place.
