TA-2022 input impedance ?

Hello, I have a Tripath amp that uses the TA-2022 chip.
I have a link to the data for that chip, but I don't know what to look for.
I need this info to match a passive pre to it.
I know my cd player output impedance but not the amps input impedance. Can anyone look at this data sheet and answer my question?
Almarg, where are you ?

Thanks Al.
I wish I knew more about this stuff.
I've went ahead and ordered a Lightspeed attenuator for it.
My CD Player is where it should be for that attenuator, but George, the builder of my lightspeed said that the amps impedance should be over 47k ohms for best results.
I guess I'll find out if it's a match in a few weeks.

Thank you for your support Al.
I look forward to reading your input here at the Gon.
