FUNCTIONAL DESCRIPTION
AUDIO EFFECT PROCESSOR
3-36
Input/Output Configuration 5
Figure 27. Block Diagram of Input/Output Configuration 5
This configuration is for Karaoke Mode I. To have this configuration, one should set Mixing and Bypass On-Chip
Function to be turned off. According to input channel source setting, one of inputs from the built-in ADC or DSDI2 is
processed by mic-echo, and the other input from DSDI1 is processed by stage effect mode or by vocal canceller.
After mixed, the result is bypassed to DSDO1. This signal is also passed to the built-in DAC and DSDO2 after
processed by graphic equalizer, volume and balance control. To obtain Configuration 5, one can send host
commands from microcontroller in the order of the commands listed in Table 17.
If one selects Output Channel Selection (command code: 0x2e) to be inverted, then two output connections are
switched.
