Aragon State one help

I just purchased a used Aragon Stage one. I run a turntable into AUX analog input. The volume for that input is much lower than for others such as DVD. I would like to A/B compare turntable to DVD but the volume is so far off between the two. The input level function seems to make no differnce on the AUX input. Any ideas how I can adjust the input level for the AUX/turntable input?

Also, the volume defaults down to -20 every time you leave a source and then go back to it. Is there any way to bypass that function?

Thanks
