A powerful transformer pair ensures complete mass separation of the input and output signals. This isolates the two signal paths, allowing for the suppression of hum and noise caused by ground loops. With an extraordinarily linear frequency response and a wide frequency range, the device can also handle high signal levels. Regardless of the signal sources used, an absolutely pure and neutral sound image is guaranteed. It can operate with impedances from 600 ohms to 100 kOhms. Inputs and outputs are available as XLR, jack, and RCA connectors. It comes in a compact, black anodized aluminum housing.
