## Questions & Answers

**Q: Can it take a 1/4 mono signal and split it into L/R channels on the 1/8 plug?**
A: No, you need a purpose built adapter for that.

**Q: Is this cable 12"tip to tip, or is is a 12" cable?**
A: Tip to tip length is 14.25" . I don't know where the 12" measurement comes from, but the cable length itself (minus both connectors length) is 10.5" Hope this helps.

**Q: Does this work for a talkbox?**
A: This is a passive adapter which simply allows an audio cable with a male 1/4in. connector to be plugged into any audio device having a 1/8in. socket.  

There is every reason to believe that it will work with a "Talk Box" if that device needs such an adapter.

**Q: Can this work in either direction, i.e., 3.5mm to ¼" as well as ¼" to 3.5mm?**
A: Dear Amazon Customer,
Yes, this MillSO 1/4 to 3.5mm adapter can work in either direction (3.5mm to ¼" as well as ¼" to 3.5mm).

Thank you for your question. Hope this answer will help you, if you have any other concerns, please contact us via support@millso.com, we will always be more than happy to assist you.
