Do you want a good answer? Or a popular answer?

Your problem description is very incomplete. "600r" is a nominal thing- do you actually need 600 ohm load on your source?

Anyway: ALL the answers can be built with a handful of penny resistors and a few clip-leads. Why haven't you just tried it?

A "full" answer would fill a book. A practical soundperson would twist-and-try, get a fine result in a few tries.

Yes, does the OP wish to maintain input impedance, output impedance or both? Is anything actually 600R, anyway? The solution is simple, provided that the problem is well-posed. I suspect this is one of those problems where if you understand the question then you don't need help in calculating the answer, but if you don't understand the question then you may be asking the wrong question anyway.

As always, some context would help us answer the right question.
