I have a denon dj mixer with balanced XLR output jacks operating at a +4dB gain level. I have these jacks connected to the balanced XLR inputs on my Edirol UA101 usb audio interface which according to the manual are rated at -10dB. I have tried recording a mix from my mixer into Sonar through the UA101 and it was successful and sounds great. My worry is this: since these the Master outs on my mixer have a higher gain rating than the XLR inputs on the interface do I run the risk of causing damage to the interface? Please let me know. Thanks!

probably won't damage thing but you may have more level than you need and may have clipping

a simple resistive pad could solve any problems
IF
they arise

you didn't say which mixer so I can't look up the specs

the Edirol UA101 USB Audio Interface

quote from site
All Balanced I/O
The UA-101 offers all balanced inputs and outputs with input level selection switches on inputs 3-8, offering either +4dBu or -10dBu levels.

As long as you're looking at around a -70 noise floor in Sonar then you know you're not introducing unnecessary hiss to the recording. The feature of level adjustments between consumer level and pro level input and output have more to do with matching voltage expectations between outboard equipment. So if you're not hearing "hiss" and you have a nice noise floor in Sonar then you're good to go.
