Hey Red,i just changed my sound card with a professional sound card as i couldn't find an alpine h700 for less than 500 euro in italy(i paid my card 350 euro) and at least i don't have to recable for just a controller,and i can use the awesome dac of the card.

The card is that :

I calculated with a program and and it came out that the output voltage are 1,2 v nominal(4dbu) and 10v max(22,5 dbu) so the voltage should be enought.
Have i understood well?Or will the card have pre-out always lower than a h700?

That looks nice, but I have a few questions....

for most people the problem with the Alpine unit is finding a place to put the controller, seems like this would be just as much of a problem, no?

how do you power it? through an inverter? if so that's taking one step forward and two steps back for sound quality.

the connections? I don't see anything on there that would fit in the car audio world....am I missing something?

Why i have to look for a place for this?This goes back with the amplifiers,i don't have to touch it.Its only purpose is to connect the pc with the amps.

It has a pci card that power all the rack,so one step forward and no step back
For the connection it has 8 mono 1/4'' jack for output and two balanced XLR(which i have on my butler tube amplifier) with 48v phantom power.
You can see here the outputs and the pc connection :


Tonight i'm gonna test it,i hope i can get good result.
My biggest fear is that it use much more power than the previous card,and i think my poor opus is already at the max.

ahh - ok, well you have fun with it!

Ok,here are the result.
With the XLR the output is very noisy,i think it doesn't have enough power to do the 48v phantom,and i don't have enough power even for just the usb touch screen.
Using the jack the touch screen was working fine,but the only cable i had was a very thin and poor one,and i still had a little noise,i hope it's just a cable issue.
The great thing is that now,with the gain of the amplifier at the minimum, i have almost the same power as before with the gain at the maximum.That with the tube amplifier,with the other cheap one i haven't noticed a great difference,someone know why?.
Overall the sound seem much cleaner but maybe it's just an impression,it seem now more cold and flat,without personality
I think it's time to take the car to a professional installer,the previous installer was a total incompetent.
