Reply to ANYONE SAMPLE VINYL WITH AUDIO 10 AND MASCHINE? Samples quiet?

I am getting back into sampling after a year or so off...having had to move out of my old set up in the UK for work.
Gradually getting a little studio set up where I am now but can't seem to set up machine to sample well here.

In my old set up I routed my dj mixer into an M-Audio Midi interface then to my laptop.

Now i have my deck going into my vestax 05 mixer, whos output goes into the "in" at the front of an NI audio 10. Audio 10 goes via USB to my laptop. The problem i'm having is that I have my signal peaking in the red on the vestax mixer, and with my master mixer output on full - the sound is coming into maschine, but just way too quiet.....

I have found a way to sample in so that its an input in machine and this gives u some recording level control but this still doesn't get the sound as high as it should be for sampling, and obviously I can normalise it but I'm sure it can't be normal that I would have to max out my mixer to sample...
Surely two NI products would work together better?

Anyone got any suggestions?
Thanks in advance
