Could I use this between a phantom power boom mic and wireless transmitter? Trying to make a wireless boom.
Asked by: Brandon
In theory & reality; Yes. However, I would caution you in doing this as you're asking for problems or cable damage in the future. The device is not really meant to be actively carried around during use, it does not have a belt-clip or pouch. You may inadvertently hit the power button and cause a disruption in the signal or feed. I might suggest the RODE News-Shooter kit (or other similar product) where the transmitter has a built-in 48v option. I've been using that for the past couple years and it's great!

Asked by: Greg
Should anyone else have my weird question, I ordered a new device and the device came with a 9.0V 0.5A (center negative polarity) switching mode power supply (AC adapter), specifically this one: GPE GPE006D-090050-Z

I am trying to connect my Shure Microflex MX412 to my Canon Vixia HF100. I know that I'll need an XLR to mini cable to finish the connection. Will this get me part way, meaning, if I hook my mic to this will this give me enough phantom power to work?
Asked by: Matthew
This will provide phantom power to xlr mics that require it. Always have a spare battery.
