## Questions & Answers

**Q: My unit has stopped working. Mini input jack may be bad. How do I return for replacement? purchased 9/2/22**
A: Try a new supply for cable to usb ie another high power charger.

**Q: Can this amplify a video signal to allow splitting on multiple viewing screens ?**
A: No.  It is for audio only (and in my opinion, doesn't even do that well).

You need a device that is specifically for video, like this:
https://www.amazon.com/MT-VIKI-Splitter-Composite-Distribution-Amplifier/dp/B0882RHYTW/
This will take a composite video input, amplify it, and provide multiple outputs.  It also does the same for the associated audio inputs.

**Q: What are the exact dimensions of the power connector? The connector has 2 dimensions, the outer diameter and the inner pin diameter (5.5 mm x?)**
A: I don't know.  My Mini Stereo Line Level Amp stopped working the second week I owned it.  I recommend buying something else.

**Q: Will it give a full 2 volt line out  RCA signal**
A: So long as the input level is sufficient to create a 2V output signal, the answer is yes.  If the input signal is not of sufficient amplitude it will/can not.
