C controls.
A desktop or laptop computer running the Windows™ XP operating system is required for the stand-alone
operation. Connect the EVM to a computer using a USB cable. A jumper (JP9) provides the option for the
TPA2054D4 to receive power from the USB or an external supply using 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.
