It beats me how having additional gain stages combined with unbalanced circuitry that introduce additional noise is somehow beneficial.
And you actually imagine yourself using a mixer into the PC utilizing more than 2 channels?
If you do, I would seriously suggest looking at a higher quality unit than the Behringer.
Personally, remember that you are already at the very bottom of the spectrum regarding mic pres, not the high end. Think "Mr. Microphone" consisting of
at least one op-amp... But hey, Behringer Does offer such specs as "130 dB dynamic range for plenty of headroom" and "A bandwidth ranging from below 10 Hz to over 200 kHz." Funny, they don't cite S/N in the specs I saw... But hey, that 200 kHz sure looks meaningful(sic)! And absolutely no mention of gain and phase linearity......Try to restrain your enthusiasm....
You'll pardon me if I tend to mistrust a 'gift horse' promising to deliver more in a 'do everything' package that costs less than half of what the otherwise cheapest 2 channel mic pre offers.
The ART is already the lowest I would go...
I would opt for signal quality over imagined versatility that, while I may be wrong, I cannot really imagine anyone actually using and receiving more benefit from than they would with a 2 channel unit featuring higher quality pre-amps, fewer gain stages, and less noise. And considering that the normal price for the Art unit is literally double the Behringer, and the ART unit being one of, if not the cheapest 2 channel pre that meets the requirements, I would be hesitant to cut the price in half for a unit portending to have 5 channels.
The ART unit, being 'self-contained' also offers the advantage of being portable, enabling you to use it with a laptop computer as well.
But of course you are free to do as you please. Just do not delude yourself in to thinking that because the list of 'features' is significantly longer that the actual topology and parts' tolerances, etc.,. are somehow better. The fact is that you are looking at an inverse relationship where the more 'features' correspond to a lower quality for each stage.
Also, please note that you want an INDIVIDUALLY CALIBRATED Dayton EMM-6 from Cross Spectrum.
