Hello ..I just purchased the UA 710 and a audio box USB. the problem I'm having is when I'm recording in pro tools I have the mute button on and record button enabled when recording and the input on the audio box USB to the left so I can hear myself due to latency...but it sounds great while recording and loud enough but when I play it back the vocal levels sound a tad bit lower...what is the problem ? I would appreciate the help thank you...

Btw I record over mostly instrumentals and mp3s...so should I just turn the instrumental down while recording?
