PlasmaSpeakers Breakthrough 03.05.06

Our first try of trying to rebuild the preamp module did not work out so well. We attempted at using different capacitors throughout the circuit.

We met up this past Sunday and reworked the Analog Devices SSM2019 Audio Preamp Chip. We were constantly getting crackling sounds from the chip until Chunxi played around with the resistors and got some great sounds out of the audio out. This chip alone can replace the preamp module that Plasma had provided us with. The volume is not as loud, but we can include a transformer to this to get a louder volume.
