I absolutely the ART T8 (8 ch) and the ART DTI (2ch) I first bought the DTI to resolve hum problems when connecting laptops and smart phones that create a bad hum when they are being charged. Then a few weeks later we did a show and had some hum in our mains and monitors. We use all powered speakers so the mains, monitors, center fill and delay speakers are often on different circuits causing ground loops. I tried the ART DTI and it cleaned it up 100%. I now have the T8 in my front end rack and every output is patched through it. I also have two DTIs that we use for outside inputs. The are also very helpful when changing from one connector to another because the have XLR, 1/4" and RCA inputs and outputs. I will never build another fron end rack without one.

Everyone should have on of these in their rack or at least loose in their bag of tricks. It makes a great DI if you dont need a pad, really inexpensive 8 channel mic splitter if you dont mind using a TRS to XLR adapter. The thing is dead quiet and doesn't add any coloration. ART outdid themselves with this piece. In my own rig I have one in my drive rack to isolate it from the processing rack. I have another to use to patch computers, ipods, and whatever last minute emergency sources someone brings me. I also have another loose that is brought out for the guest artist's CD, Ipod, MP3, computer to be able to patch in from on stage. If you have hum or buzz in your rig you owe it to yourself to try one of these things out, and at less than 20 bucks a channel its a great investment.

I purchased the T8 to reduce interference on longer cable runs and to change connector types easily for PA and on location recording application. It did that very well. I am not impressed with using it in the studio however, because to my ears, it changes the tonality of sound a bit, when attempting to capture a higher quality of recording. It seems to be built very well and the customer service is very good.

I've now purchased 2of these units. They're great for eliminating ground loop an they're quiet. It also reduces the cost of cabling because they have most connectors covered. I go from the snake directly into the T8, then into the mixer. I love the price and the quality is good. I recommend it and I recommend ZZounds. I haven't had to use manufacturers support but this survey makes you put something; so I put 5-stars.

I bought this to re-amp raw guitar signals, hoping that its noise performance would exceed that of the ADA8000. The main difference between the two is that the 8000 introduces hum before the preamp stage, and the 8200 introduces hum after the preamp stage. With no input signal, if the 8000's gain knob is set low, there is no hum audible at the output, only hiss. As the preamp gain is increased, hum will become audible and the hiss will also increase, until they are about equal in level. With no input signal, if the 8200's gain is set low, hum can be heard along with hiss (hiss equal in level to the 8000). As the gain knob is increased, hiss will rise but hum will not, until eventually the hiss masks the hum. The end result is that, if both units are sent a strong signal that allows the gain knobs to be set low, the ADA8000 lacks the hum that the ADA8200 introduces. If you send both units a weak signal that requires raising the gain knobs, then the 8200 will not boost the hum as the 8000 will, but this scenario is not as desirable as providing either unit with a strong signal in the first place. Bottom line, if you send either unit a strong signal, the ADA800 is quieter than the ADA8200 in regards to hum. Both have the same amount of hiss. I isolated both units and made absolutely sure that the hum was internally generated and was not part of the input or any ground loop. Most importantly, the hum (or his) should not be noticeable if not using either unit before a high gain guitar amp, as is the case when re-amping. This is a special case that exposes even slight differences in noise performance. I can recommend the ADA8200 for other applications, but not for my intended use. Also, I am using a MOTU 2400 audio interface and have learned that these units have a compatibility issue with the ADA when both optical cables are used simultaneously. Even though I must return the ADA8200, I feel that it is a good value if used as a standard interface.
