From the description: "it is also a convenient tool for musicians as it can power up to 10 effects pedals." Is this true? How? No power output.

It's a passive unit and it will not power up any equipment like guitar or keys. One end has unbalanced input (TR) and parallel out the other end, has balanced XLR so it can be used in a XLR mic input on a mixer. The main purpose is so in a studio setting a guitar player can go into an amp via (parallel out ) and XLR to the input on PA /mixing board to record effects while recording . This will not solve your issue, Example -in my band we rehearse in my studio garage my bass player doesn't bring his amp-( to heavy ) he plugs his bass in to a DI box with 1/4 inch TR (Tip Ring) and the other end I use a XLR cable from the DI box to Mic input on my mixing board. It increases the impedance --Unbalanced to Balanced.. It also has a ground lift to eliminate ground nose (BUZZ) Look for a book "The Ultimate Live Sound Operators Handbook" by Bill Gibson It explains everything. Hope I was helpful.

Can I use this with an audio interface to reduce clipping on Guitar Rig 5?

Yes. It will do this by converting then line input from your instrument into a balanced xlr for your audio interface. That is exactly why I purchased this

I need to transform a xlr balance output to and an unbalance one, can i use this device? looking the photo the xlr can be input or output! thanks

Hi, yes you can use this unit. You may check other details of the unit by visiting our website pyleaudio.com. Type the model number on the search box PDC21 for more details. Thank you.

Could I use my balanced 1/4 to XLR cable to replace DI box?

i tried to use balanced 1/4 with xlr adapter, and never got a reliable connection. di box worked fine.
