2 Operation
2.1 Quick-Start List for Stand-Alone Operation
Follow these steps to use the TPA3111D1EVM stand-alone or when connecting it into existing circuits or
equipment. Connections to the EVM module can be made by inserting stripped wire or banana plugs for
the power supply and output connections. The outputs also can be connected via Molex connectors. The
input connectors are RCA phono jacks.
