Inputs and Outputs

The audio output lines from the power amplifiers are separate all the way to the edge of the platform (output jacks J7, J8, and J9)Ðthe OUT± lines from the power amplifier sockets are not tied to each other or to platform ground. This allows the TPA701 power amplifier EVMs to operate in the highly-efficient bridge-tied load configuration.
