Art DTI User Manual

DDTTII
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 DUI the obvious choice.
