My console has 8 subgroups that have direct outs that are 1/4" unbalanced outs. The 8ch. AD/DA box has 8 inputs and 8 outputs that are also 1/4" unbalanced. This allows me to send directly to the sound card from the subgroups. You can install up to 4 of these DSP2000's in 1 PC for a total of 32 inputs.

Interesting. I assume that the converter clocks for all channels are synchronous, and that you can slave one box off the other?

I just want to use 2 units for a total of sixteen channels simultaneous. My problem is how do you split the 16 channels on the snake to go balanced into the console and then unbalanced into the AD/DA converters? I have found some 8ch. mike preamps that have XLR balanced inputs that are 2K ohm loads.

That's standard.

My console has 150 ohm inputs.

No, it doesn't, and I don't even know what kind of console you own.

If I use some kind of XLR Y's to split the snake the load on the console would drop to 139.5 ohms if my math is right.

You math may be right but your assumption is wrong.

Also the 8ch. mic preamps S/N ratio is listed as being greater than 80db. Isn't this kind of low?
|
It Is What It Is. At what gain is S/N specified? Perhaps you're confusing S/N with EIN (Equivalent Input Noise), which is usually something around -126 dB or lower.

Isn't signal to noise usually listed as a negative number?
|
No. If it was, then the noise would be greater than the signal. Remember the ratio is signal to noise; when expressed in decibels, if signal is greater than noise then the number is positive. It's the Power Of Logarithms!

I think my sound cards AD/DA box is listed as being around 105.

It may very well be, or may not.

I'm doing this on a budget and these 8ch mic pre's are only $99.00 Does anybody know of any other way to do this?

Get a couple of Firewire mic pres. Get a Pro Tools system with appropriate A/D hardware. How much do you want to spend?
