Applied Research and Technology (ART) announced the release of T8™ (Transformer Eight), a high-quality totally passive audio interface that uses eight transformers to separate input and output signal grounds, isolating two systems and reducing hum and ground-loop noise. The T8’s audio transformers have flat and wide frequency response and handle high signal levels while maintaining an isolated balanced output. The transformers are wound for 1:1 unity gain and have been designed for use with impedances from 600 ohms to 100k-ohms.
The T8 provides balanced XLR, 1/4-inch phone and RCA-type phono connections on all inputs and outputs simultaneously. The 19-inch single-high, all-steel case and its passive design, full feature set, rugged construction and high-end specifications were designed for live sound, permanent/fixed install and virtually any P.A. application. The T8 retails for $179 and has been available at music specialty stores worldwide since April 2005.
