I wouldn't recommend trying vinyl control without a preamp. If you want, you can bump the input gain by using Mixxx's software pre-amp (available in the Vinyl Control pane of the preferences). Though the Maya44 doesn't have any input gain controls, this software amplifier will do its best to amplify the signal. However, depending on your environment, it can be extremely noisy. Try it out though; you may be lucky. But remember the environment that you're in can strongly impact the quality of your signal.
I use a $17 Pyle Pro preamp on one of my turntables (Stanton STR8-60) and my other (Stanton T.80) has a built-in preamp that I select. Both work fine; the signal quality is almost excellent. Joe Adam Spence @ Wed 22 Jun 11 21:30:27 +0930:

So do you think i still need a hardware preamp with the Maya44 USB.

Yes, there are no input gain controls. But this is not a problem for me, as the input levels are fine. What are you using your card for? If it's for vinyl control, make sure you have preamps attached as the Maya44 does not have internal phono-level preamps. If you're using it as a microphone input, it should work fine. I haven't tried that though. Now, the Maya44 has 3 output level controls: master, line 1 and line 2. I think Line 1 and Line 2 are called "Line" and "Line 1" or something due to poor ALSA naming. On my system, ALSA defaults by turning master to 0, which makes things coming out of the card barely audible. So, you'll need to turn that up quite a bit. I turn it to full. The other two control whether you pass audio input from Channels {1,2} or {3,4} directly to the output (I think it ties them to both Channels {1,2} and {3,4} of the output, but I haven't tested this). I'm not sure if this is analog passthrough or if it's digital. Obviously, though, you want to leave these muted if you use timecoded vinyl, unless you like treating your audience with annoying high-pitched noises. :P I've used this card with every Linux Kernel from about 2.6.37 onwards. Important note: your computer may not be able to handle four channels of input and four channels of output! This is really weird. I've tried the card on 4 computers. Two of them were Intel's newer Core system. On my Core i7 desktop, 4 channels of sound input and 4 channels of sound output isn't a problem. On a Core i5 Dell desktop, if I tried that configuration, Mixxx would crash and ALSA would complain about insufficient bandwidth (check the output of dmesg). On a Core 2 Duo laptop, I had the same bandwidth issues. But on a slightly newer Core Solo laptop, all 4 channels worked, but with some occasional skipping. Crazy, huh?
