2.4.4PC and I2C Interface (J300)

The PC interface using the attached special cable to parallel/printer port on the PC. This makes it possible to control the TAS3002 digital audio processor totally from the PC using the special DCT software saved on the PurePath Digitalt amplifier CD-ROM.

The PC interface can also be used to control the TAS3002 from an external microcontroller of your own choice.
