The Iso-Max PO-XX is a single channel output isolator for both balanced and unbalanced signals where extreme signal handling is required to drive long cable runs. The design begins with an extruded aluminum case that comes standard with gold plated XLR connectors. Plug and play easy to use, this passive interface does not require any power to work. Inside is a high performance nickel core Jensen transformer that is able to withstand signals in excess of +26dBu without discernible distortion while delivering a linear response to 150kHz. This provides galvanic isolation between the input and output to eliminate hum and buzz caused by ground loops, rejecting noise by as much as 110dB.
