ART DTI overview

  • 1Description

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.

    ART DTI reviews

    DTI - Transformer/Isolator is rated 3.9 out of 5 by 8.
    Rated 4 out of 5 by from Gigsaver Great versatility, a real gig saver. A must for people who do audio for a variety of different events.

    Rated 2 out of 5 by from Low Quality It looks great and it has RCA, but, do not waste your time or money. Spend the extra ten bucks and get the Ebtech HE-2-XLR and buy the converters. Why? Because it does eliminate much of the hum, but adds a squirlly noise on the high end. I bought both this and the Ebtech HE-2-XLR at the same time because there were no good reviews so I thought I would buy both and compare. I returned the DTI and bought another Ebtech. Please don't try and be cheap, spend the few extra dollars and save yourself some time.

    Rated 1 out of 5 by from Not good enough for professional audio! I give it one star for form-factor. Otherwise it fails in the MOST important aspect of all: SOUND QUALITY. Not much humm/buzz reduction in my experience. You 're better off with the EBTECH Hum Eliminator (which costs a little more). But you WILL get what you pay for!

    Rated 4 out of 5 by from Just what I needed I use this between the audio signal from the sound board to the audio input of a video camera. Before using this I had a hum when I was plugged into the wall outlet and not using battery. Once in place the hum has dissipated and I now have clear audio on my recordings.

    Rated 5 out of 5 by from Has RCA inputs The DTI box has the RCA inputs I needed for running a unbalanced subwoofer out RCA jack to the balanced XLR input jack on my Crown CE 1000 subwoofer amp. The Ebtech HE-2-XLR does not have RCA inputs. The hum is gone in my home theater room.

    Rated 5 out of 5 by from Works Great! We use this product to clean up a long unbalanced streaming video feed that has a nasty buzz. Works great!
