CLARIFICATION OF OUTPUT CONFIGURATIONS

DAC, ADC, and port assignments are arbitrary; however, ports

are optimized for certain configurations. Use the guidelines in

Table 7, Table 8, and Table 9 when selecting ports for particular

functions. Note the following for each of these tables:

•

HP is the output capable of driving headphone load and

power

•

MIC is input that supports microphones with MIC Bias

and boost amplifiers

•

LO is the line level output

•

LI is the line level input

In desktop applications with discreet jacks (the default

configuration), assign the ports as listed in Table 7.
