[AudioI] Input Impedance and coupling of Zero board line inputs?

[Tom Garwin]

Sorry if this information is listed somewhere but I have two questions
about the stereo line inputs to the Zero board:

1) What is the input impedance?
2) are the inputs AC or DC coupled?  In other words is there a
blocking/coupling capacitor preventing DC to reaching any on-board
amplifier or the A to D chip itself?

Thanks
