Hi Colin,

That chip is not worth wasting any time on. There are
much better, yet simple, alternatives that can handle
huge signals without problems. Example:

With suitable transformers, these chips will work UFB on LF/MF.
Considering the high level capabilities of these mixers, make
sure that you wear adequate eye protection (welding goggles)
before starting Argo :-)
