C controls.
A desktop or laptop with Windows™ XP installed is required in the stand-alone operation. Connect the
EVM to a computer with a USB cable. A jumper allows the TPA2050D4 to receive power from either the
USB or an external supply via banana plugs. The inputs accept standard RCA plugs. The speaker output
connection accepts banana plugs. The headphone output connection accepts standard 3.5-mm
headphone plugs.
1. Insert the CD provided.
