Output sound level from gramophone and from computer should be the same

Question

Dear friends,
Why the output sound level isn't equal if we listen the LP directly from the gramophone (AUX1) or from the computer during the recording the track on the computer?
We are using The E-MU 0404 USB 2.0 Audio/MIDI Interface:
http://ixbtlabs.com/articles2/proaudio/emu-0404-usb.html
http://www.emu.com/products/product.asp?product=10447&nav=features
and we have connected E-MU with the (gramohone) speakers through the headphone output on the E-MU and turn the headphone level to the maximum, but the sound level is still lower from the same speakers.
If we compare the track after the recording with the LP on the gramphone is the level of the sound the same/equal.
So we need to have all three sound levels equal:
-from the LP form the gramophone
-from the computer during the recording
-from our track on the hard disk after the recording
Thank you for your answer.

Answer 1

function(){return A.apply(null,[this].concat($A(arguments)))}
Connecting loudspeakers to the headphone output on the E-mu sounds like completely the wrong thing to do altogether - you should
only connect headphones to a headphone output, and nothing else at all.
We will buy the cable as you mentioned and connect it in the line level (S/PDIF).
function(){return A.apply(null,[this].concat($A(arguments)))}
Almost certainly you will need to adjust the monitoring levels in Patchmix to get this the way you want it
Then we will try to adjust the monitoring levels in Patch (I will report if and how did we manage it).
