Manufacturer Info:

The T8 (Transformer Eight) is 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 transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 ohms to 100k ohms. 

The T8 provides balanced XLR, 1/4in phone, and RCA type phono connections on all inputs and outputs simultaneously, with reversible rack ears for either the XLR or phone connections in the front. The T8 fits easily into virtually any audio system and is a clean patch point between all types of systems.

In excellent cosmetic condition.
