The DTI (Dual Transformer/Isolater) from ART is a high quality, totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise.

The unit's audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the DTI a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 Ω to 100k Ω.

Useful for making a "clean" interface between a computer based audio workstation and a speaker system, isolation on long cable runs in a fixed installation, isolation of a signal source from any recording equipment, or in many cases, just a safer connection between two audio systems.
Provides XLR, 1/4" phone and RCA type phono connections on all inputs and outputs. This allows the unit to easily fit into virtually any audio system and be the clean patch point between all types of systems.
A compact black anodized, all aluminum case and passive design allow the DTI to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J. and virtually any PA application.

I'm thinking of purchasing this unit, but am curious to how you would connect it from your motherboard to PC speakers. I know it has RCA inputs/outputs, and would assume:- Speakers connect to the output?- Motherboard connect to the corresponding input?Only asking, as their website doesn't have an instructional/manual on this...Thanks.

You can only use this line level unit with internally powered speakers that connect to the motherboard with line level signals, not speaker level. Usually, this means via the connectors on the unit itself.

LINE input or MIC input or both ?

LINE input or MIC input or both ?

Both, but I think only one at a time.
