ARTcessories

Designed and Distributed by Applied Research & Technology • Made In China

The DTI 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

DTI’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 Ohms to 100k Ohms.

What further sets the DTI apart from other lesser isolation

boxes is its connection versatility. We have provided XLR,

1/4” phone, and RCA type phono connections on all inputs

and outputs. This allows it to easily fit into virtually any

audio system and be the clean patch point between all

types of systems.

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 a signal

source from your recording equipment, or in many cases,

just a safer connection between two audio systems, the

DTI can accommodate.

The compact black anodized all aluminum case and it’s

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. It’s full feature set, rugged

construction, and high-end specifications make the DTI the

obvious choice.
