Using Audio Hijack To Record From Powered Mixer, looking for best way to record from powered mixer to computer Options

[johnnyboy]

I am working with a new sound system setup at my church and trying to get a good recording set up using the Behringer powered mixer PMH1000. I am recording to a mac mini using audio hijack.

In the past we used a Telex device that just has an stereo jack input on one end and USB on the other. We were recording directly from the wireless mic reciever and using the effects on audio hijack to enhance the sound and it did quite well. Now we want to run the mixer to the computer so we can record everything, the problem is now I'm getting a lot of hissing and diminished sound quality.

I am connecting to the mac mini from out of the main line from the mixer as Behringer suggests. Some people have told me I need some type of interface device to change from analog to digital, but I was wondering why I was able to get a good signal from the wireless mic reciever without an interface before.

What I would like to know is what is the best set up to use to record from a powered mixer to the mac.

Should I not use audio hijack?

Do I need an interface?

If do need an interface device what is the best deal I can get for a simple operation? (low budget)
