## Questions & Answers

**Q: I'm looking for options for building a buffered, multi-output splitter for a guitar signal to feed several amplifiers or DI lines. Yay or nay?**
A: If you are buffering for each input to each transformer there should be no problem but, there are no specs on the frequency characteristics.  The stated impedance is 600 ohms but with the small size, I would think the low-end frequencies would drop off quite rapidly.  My application was for isolation of the ground circuit.

**Q: primary to secondary hipot ?**
A: Not sure as I had no need to test.  My application was in a simple iso circuit for computer audio interface.  They were great for the price.  Previously I would use Radio Shack transformers for the same application.
