What is the best signal routing choice in this scenario?

I'm in the process of improving what I have as far as studio gear. I don't have all of these things yet, but ultimately I plan to buy an RME Fireface, a Sytek MPX-4Aii preamp unit, and then eventually one more of each. I will either be recording into the Fireface or into a 1/2" analog 8 track machine that I already have. The Sytek preamps have no output level control--all you get is a gain control, mute button, phase reverse, and phantom power control. I may be operating under an erroneous theory here, but I've always been under the impression that one should run one's preamps so they are close to clipping but they don't actually clip in order to get the best S/N ratio. If I'm going to do that, I want to be able to use my mixer (an Alesis Studio 24) to attenuate the preamp signal before it goes into the tape machine, as it doesn't have any input trim control. I don't believe the line ins on the Fireface do either. What I'm worried about is taking the nice clean signal from my good high-quality Sytek pre and jamming it through the cheap-ass pre on the Alesis board (the line ins on the board's channels do pass through the preamp, I believe). I'm considering putting the preamp signal into the mixer at the point of the channel insert instead, as that would bring it in post-trim and pre-EQ. However, that's not a balanced input. So my dilemma is this: do I give up balanced connections from my pres into my recording device for the sake of keeping the channel pres on the Alesis out of the chain, or do I simply use the TRS line ins on the board and not worry about whatever changes that might impart to the sound of the outboard pre?

Yes, you are operating under an erroneous theory, for the most part.

The whole point of having "nice" pres - like the Sytek - is so you don't have to worry about all that crap that you're worrying about right now. :D

I see. So all I need to do is just hook the pres straight to the recorder and adjust the pres for the proper level on the recording device?
 
You got it.

Unless, of course, you'd like to use the mixer for things like signal routing, monitoring, effects sends, or maybe you want to use the board's EQ or something.

But if it's just for what you're talking about, then it's just taking up space. :D


(Hopefully your recorder has the option for -4 or +10 at the input ... in which case you've got extra control right there as to how hot the signal is going to be going in. But if not, then no big deal, really.)

The analog machine (a Tascam ATR-60-8) doesn't. Dunno about the Fireface. I'll cross that bridge when I come to it, I guess.
 
With the tape machine, you might want to worry a little more about the signal to noise ratio you're getting, obviously.

Not so much with the RME.

The nice thing about the Sytek is that it has a much larger sweet spot than a "budget pre," hence why it tends to be thought of as more of a pro / semi-pro piece of gear. Pretty much any position on the dial is going to sound good, clean, full, etc. So yea, as long as you're not clipping anything, you just use the gain on the Sytek to control how much signal you're feeding the next stage ... that's really what it's made for, so I would hope it would work in that capacity! :D

Chess has you covered, so I'm just here to co-sign. Don't take that pristine output from the Sytek and run it through an Alesis anything. Think of it as having an optically perfect/squeeky clean pane of glass, and then laying it on top of a dusty smudgy old pane of glass. It doesn't matter how perfectly clear the first pane is, you will only see as clearly as the dirty pane.
