This is also a circuit that Bryston shows in their published pre-amp manuals and as you can see from the board pictures there aren’t really many components to it beyond … WebDIY two channel Audio Mixer/Amp. I wanted to design and build a mixer/amp from a single supply (9V battery), under one condition, avoid input/output caps to get a better frequency response at lower frequencies. I would like to share my thought process, any feedback is much appreciated. The circuit provides a virtual ground through the use of ...
