DSP always operates in slave mode. 2. In either analog or digital input, the signal is inputted to SDI0 port. 3. In case of both digital and analog output, DSP input port is only digital input. When analog signal is used, disconnect digital input signal from this demo board. Jumper setting description 1. Set up the 5V power supply line. NOR (*default) : AC Adapter USB : 5V of USB port 2. Set up the jumper to input the sound signal to input ports SDI0 (*) :J4 set SDI1 :J5 set SDI2 : J7 set SDI3 : J8 set 3. Set up the jumpers to output to SEL_AOUT and SEL_DOUT connecter.
