how do i convert the mpc outs to adat(2000xl)

Whats up guys i have a motu 828 that has the option for optical adat and it also has 8 analog inputs on it. I am using a mpc 2000 xl with the 8 out lets and a motif with the 6 outlets. The motif es i have has a optical out put but its not adapt so i cant send 8 channels out of it so i was wondering if there any thing for a good price that i could run 8 analog tracks into that ill be able to out put it to adapt optical so i can use all my ins and outs on my motu. I want to use the 8 outputs on the motif for the 8 inputso n the motif and find out was so i can covert my analog signal to optical adapt on my mpc so i can use those inputs also.

I guess it depends on the price tag. I'm not sure if there is anything cheap that would sound good. For about $600, you can get a Frontier Design Tango 24. That's sweet sounding. Maybe Behringer has something, but I wouldn't trust it.

Good luck.

Alesis AI-3. They are like 400. 8 ins and 8 outs. I got one and I think it sounds better than the converters on the 002.

behringer ADA8000, £170 8 analogue ins.
