Impedance on Line jacks of UMC202HD

Hello,


I'm a RF engineer with an audio problem.


I have an old system that I'm trying to interface with that has a 0-60KHz baseband that I need to capture and play out in real-time. It looks like the Line In/Out on the UMC202HD will do the trick pretty handily at the 192KHz sample rate. The mux has a 135 Ohm interface. 


Can any of you audiofiles tell me what the impedance is on the UMC202HD line in/out connections so that I can build the matching circuit?


Also, can anyone confirm that the Line In/Out jacks will play and record up to 60 KHz of baseband simultaneously? I'm used to designing systems between 300 MHz and 20 GHz, so I'm a bit out of my element. 


Thanks in advance!
