The T8 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. Connection versatility sets the T8 apart from other isolation boxes. The T8 provides balanced XLR, 1/4 '' phone, and RCA type phono connections on all inputs and outputs simultaneously. Frequency response is 10 Hz - 50 kHz a power supply is completely passive. Dimensions: 44 x 483 x 95 mm. Weight: 1,7 kg.
