Distorted recording in Traktor Scratch Pro 2

Hi guys,
Ive been trying to record using Traktor Scratch Pro 2 version 2.1.2. Ive been doin it by using the record output of the mixer (DJM800) going to the Input of Deck A on my Audio 10. I have then changed then selected the External source within the mix recording settings and set the external input to Input Deck A.
When starting the recording a signal is being received but it is limiting out and the result is very distorted and bad quality.
I have read other posts on the internet and they said the problem may be that the inut channel is set to phono and not line. I have tried changing the the input to line but I am unable to select it!
Does anyone know if this is the case why the recording is distorting and if so how am I able to change it from phono to line?

All help wud b hugely appreciated as im dying to get my mixes recorded!

Many thanks!

 

have you tried different wires? ive had old rca cables give me problems with distortion, or if you have wires crossed. for example if you had a usb wire underneath a power wire it can give you problems.

 

Yes ive tried differnet cables - think the problem is its a phono signal coming in - but Im not able to change ti to line!
Any ideas?
