ART T8 8-Channel Transformer/Isolator

No longer available at zZounds
A complete hum-destroying machine, the ART T8 isolates input and output signal grounds into two systems to curb ground-loop noise.
The T8 (Transformer Eight) is a totally passive audio interface that uses 8 transformers to separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The T8's audio transformers have flat and wide frequency response and handle high signal levels while maintaining an isolated balanced output. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 ohms to 100k ohms.

The T8 provides balanced XLR, 1/4 in. phone, and RCA type phono connections on all inputs and outputs simultaneously. The T8 fits easily into virtually any audio system and is a clean patch point between all types of systems.

The T8s mounting ears are reversible so you can have either the XLRs on the front or the 1/4 in. and RCA phono jacks on the front. This maximizes flexibility in cabling your system. Whether you need an interface between a computer-based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of multiple signal sources from your recording equipment, or in many cases, just a safer connection between two audio systems, the T8 can accommodate.

"8-Channel Transformer fixes ground loops with powered speakers"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
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.
