INTRODUCTION
Thank you for purchasing the ART T8 Universal Eight Channel Transformer Isolator. This is a rock solid, road-worthly 8 channel transformer isolator. “Hum” in an
audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60Hz ( or higher harmonic) hum created by electrical wiring.
Typically, these loops are connected via grounds, more commonly called “ ground loops”. The safest way to eliminate unwanted noise is with the T8.
The T8 is a quality totally passive audio interface that uses eight high performance low distortion transformers to totally separate input and output signal grounds,
thereby isolating two systems and reducing hum and ground-loop noise. The T8’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 T8 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 for use with impedances from 600 Ohms to 100k Ohms.
What further sets the T8 apart from other lesser isolation boxes is its connection versatility. We have provided XLR, ¼” 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. All ¼” and RCA phono jacks
are on the front and all XLR jacks are on the rear. You can use any combination and since the jacks are directly paralleled you can also use them as signal taps or as a
signal splitter.
The T8’s mounting ears are reversible so you can have either the ¼” and RCA phono jacks on the front or the XLRs 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.
The 19” 1U black all steel case and its all passive design allow the T8 to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually
any PA application. It is equally valuable in a variety of studio and AV applications. Its full feature set, rugged construction, and high-end specifications make the T8
the obvious choice.
APPLICATIONS:
LIVE SOUND, D.J.
Long unbalanced cables are more susceptible to picking up hum , Using the T8 to help balance these and eliminate any hum.
When DJs set up for different jobs there is a potential to pick up hum due to the differences in house wiring, using a T8 Eliminates the potential for hum.
