greetings all,

I'm in the market for a computer-based hardware interface to record vocalists with a variety of microphones including condensator mics.

I want the vocalists to lay down lyrics to pre-produced tracks, recording using a pc-based sequencer (e.g. cooledit).

I will build a soundproof booth for the vocalists and arrange the recording i a control-room.

The scope of the recordings is independent releases on vinyl.

Question is: What type of interface will I need to do this?
what are others using?

Things I'd like:
Firewire
record multiple tracks simultaneously
talckback to artist
outboard mixer-console for ease of mastering final product (not decisive)
one single unit (reducing cabling, though not decisive)
good sound quality
1K$ price range

Initially I was excited to learn about Mackie Onyx 1220 with the firewire interface and talkback function - but is this mixer suitable?

Are there existing better performing (sound-quality-wise) products for the buck for my purpose? (price-range matching the onyx)

E.g I'd like if it was possible to use the Onyx' faders and knobs as a midi-interface for ease of mastering. Since it isn't and since the eq's are bypassed when recording, it's just waste of resources.

Hope you can help and suggest a product that will introduce the most functionality and sound quality for my purpose and budget.
