Michael,

There are several ways to accomplish what you want.  One simple methods is to
send speaker level audio up to the cupola and reduce it there to line level
using an audio transformer.  Another option is to use baluns at each end.
Third, you might be able to use the twisted pair cable as is for line level,
depending on how much and what kind of noise is present.
