Fantastic value; super easy to set up and use
I've owned a fair amount of Behringer gear and I've actually never had any issues with any of it. Granted, it's "bargain" equipment, with some gear noisier than others, but still a really good value for the price. The ADA8200 is perhaps one of the best pieces of Behringer gear I've ever purchased.
The set up is so simple, it's almost hard to mess up! In my setup, I'm using an M-Audio 1814 FireWire interface. I set the Sync switch on the back of the ADA8200 to Master 48.0 Khz, plugged the optical cable into the Out of the ADA8200 and into the In on the M-Audio 1814 and that was it. Of course, I had to check the settings in the audio control panel for the M-Audio to ensure that it was set up to sync to external clock.
I've only been using the unit for a couple weeks, but it's been flawless so far. The preamps don't seem to offer quite as much gain as the built-in preamps on the M-Audio, but they still offer plenty; more than enough for my needs. I haven't needed to use the outputs yet, so I have no comment on those.
The red finish on this unit is really nice to look at. It's a well put together piece, but is standard fare for Behringer, meaning it's not the most rugged unit with the highest quality parts. The knobs are sturdy enough, but not as "solid" as on something like the Focusrite Scarlett 18i20. As with the rest of the Behringer gear I've owned, however, with proper care, I expect it to last for years. I still have a rack mount mixer and a headphone preamp that are both over 12 years old and still work fine.
Overall, I don't think you can beat this unit for the price and features and I highly recommend it to anyone looking to add 8 channels of ADAT to their setup.
