ART T8 - Eight-Channel Transformer / IsolatorThe T8 (Transformer Eight) a high quality totally passive audio interface that uses 8 transformers to separate input and output signal grounds, thereby 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. This gives the T8 a very clean and neutral sound with a wide variety of signal sources. The
