This should help. I found it in the 802's manual.
 

i have the manual too and it dont work now i got everything setup through usb but when i play music or any other sound coming out of my pc i hear crackling sound ,i have my amp and speaker coming out of ctrl room out

I'm new and I've been reading various forums on how to get started and if I had any hair I would be pulling it out! This graphic is probably the most valuable piece of information I have found so far.

Based on this, I see no reason why the Apogee Quartet wouldn't be a great solution for use with my MacPro.

I tried that too don't work I cancel all the usb and went with trs cable got everything working but now I have latency problem

You need to set up the proper drivers in you DAW or Amplitube. Go to your settings and make sure you are using the included ASIO driver. Not ASIO full duplex. Not ASIO mulitmedia. It has to be Behringer ASIO or something to that effect. This should also be in the manual.

ive tried every asio driver there is and nothing work i think its time to put everything in the recycling bin lol

and ive read that asio driver asio4all dont work well with win7 it cause more problem

Make sure the button marked "to main mix" is depressed. If it's not depressed tell it you want to stay friends.

If all else fails, buy a proper audio interface. Any proper audio interface. No need for a mixer. Sure it looks cool but what are you mixing that can't be mixed in the box?

i made sure all the button were right i tried them all ,i was looking to purchase a usb guitar link but i have no idea if there are any good

I still think it's user error but, check out the Line 6 UX interfaces. They are decent and come with amp emulation software. Of course if you want to do more than just guitar, you'll need an interface that does more than just instrument level DI. The M-Audio FastTracks work just fine. It all depends on your budget. This gives you a relatively good scale on price versus functionality: Canada's Music Store, Musical Instruments - Long & McQuade Musical Instruments

ya i think its a user error i cant figure out ,now everything i play through my pc i get latency so i think i need a sound card

You did not mention your OS. You mentioned Win 7 but is that your OS? Most sites have yet to update their info in regards to Win 8. In fact, why don't you post your full system specs so that we can get a better idea of what you are dealing with. Hardware, software, ram, cpu. There shouldn't be any latency at all in Windows. Try this tool to see what kind of potential you have: http://www.thesycon.de/dpclat/dpclat.exe

Sounds like you need to increase the buffer size.

im running win 7 ultimate 32 bit 4gig of ram intel core 2 duo e7400 2.80ghz and onboard sound card realtek,i just rab the tool and it says current latency is 188us
