Hi,

Is Input impedance of LINE2L/LINE2R pins 80kΩ?

Best Regards,

    Hi Tadahiko-san,

    Thank you for your question. Many of our engineers are taking vacation due to the Christmas holiday in the US. Once they return from the holiday, they will address your question. I apologize for any inconvenience this causes.

    Hello Kuramochi-san,

    will the inputs be used differentially? The differential input impedance is more straight forward. A differential input with 0dB attenuation is ~80kohms. A single SE input with 0dB attenuation will have an input impedance of ~35kohms.

    Things get a little more complicated when more inputs are enabled as SE.
