PI-XX - Overview

The Iso-Max PI-XX is a single channel line input isolator designed to eliminate noise in professional balanced audio systems by isolating the input of the connected device.

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 Jensen transformer that is able to withstand signal levels to +19 dBu at 20 Hz without discernible distortion. This provides galvanic isolation between the input and output to eliminate hum and buzz caused by ground loops, rejecting noise by as much as 124 dB.

You simply connect the PI-XX between the source and the input destination to eliminate ground loops, electromagnetic interference (EMI) and RFI problems. The PI-XX will quietly go to work without introducing distortion, phase shift or artifact of any kind.
