The 8-channel multi-interface audio isolator is a high-quality, fully passive audio interface that uses 8 to separate the input and output signal grounds, isolating the two systems and reducing and ground loop noise. The T8's audio have a flat and wide frequency response that can handle high signal levels while maintaining isolated balanced outputs. This gives the T8 a very clean and neutral sound from a variety of signal sources. The are wound with 1:1 gain and are designed for impedances from 600 ohms to 100k ohms. The versatility of connections sets the T8 apart from other isolation boxes. The T8 offers balanced XLR, 1/4-inch phone, and type phono connections simultaneously on all inputs and outputs. The T8 easily fits into almost any audio system and is a clear patching point between all types of systems. The mounting ears of the T8 are reversible so you can place the XLRs on the front. The T8's full feature set, rugged construction and high-end specifications make the T8 the obvious choice for live sound, permanent/fixed installations, DJ and virtually any PA application.
