What is the purpose of C1 and C2?
Also, is there an obvious way to AC couple the input?
Thank you.

C1 and C2 (220pf) are for stability in the feedback loop.

You can AC couple simply by adding series cap to the hot input(s).
Remember for SE you must short -IN to IG.
For balanced use a cap at each input.
