I am getting a MacPro with Logic 8 Studio.

Now I am trying to decide on an Interface.
(between the Apogee Ensemble, or the Lynx Aurora 8LT)

But before doing so, I have this question on whether it was possible &/or advisable
to use a Mixer with a built-in Interface instead? - (and if so, which model could be suggested).

I am building this home-type studio inside a Social Club, where we have live performances.
The Social Club will be set-up with a live sound system.

I wanted a Mixer that I could also possibly use for both the live sound performances and the studio as well.
I thought it could serve two purposes (for recording & live sound) - and thirdly, also record the live sound performances.

Is such a thing advisable? - or is it better to keep the two separate? - (and just stick to the Mac/Interface system for recording?)
Then, just get a Mixer for the live performances? - In this case, how do I record the live performance?

In this connection, I checked out the Tascam FW1884 ($1,000) - Would this be better that a Mackie, Euphonix, etc?

However, if it is not advisable to go with Mixers (instead of an Interface) - Then I will move on to choose an Interface.

Thank you.
