## Questions & Answers

**Q: will it work in both directions ? I need to go Balanced to unbalanced.**
A: I never thought of doing this. Lucky for you I had a XLR to 1/4 mono.  

I got Zero output. Which makes sense I guess. Can't go in an out :)

**Q: Is this for a guitar with traditional passive pickups? I have a Fender Stratocaster with stock pick ups (not active).**
A: Dear A. Smith,Yes，it is .

**Q: how can i use this device to have a clean audio signal from a pioneer dj mixer to an iPhone for live streaming?**
A: Use an interface and a daw to adjust the sound and having a quality cable helps as well such as : Mogami cables or monster cables.

**Q: I have a noisy guitar pedal chain; will this suppress noise as the last unit before going into the guitar amplifier?**
A: This direct box does NOT have noise suppression built in. Most likely, if your signal is already noisy this direct box will also pass the buzzing/noise along to the next item in the signal path.
