The Iso-Max PO-2XX is a two-channel line output isolator for balanced signals where extreme signal handling is required to drive long cable runs. The design begins with a rugged flanged enclosure that comes standard with gold plated XLRs and a removable screw-down barrier strip for easy installation in NEMA enclosures. Plug and play easy to use, this passive interface does not require any power to work. Inside are two high performance nickel core Jensen transformers that are able to withstand signals in excess of +20dBu 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. To further optimize the performance, a bottom mounted eight position ‘set and forget’ dip switch enables the user to configure the PO-2XX grounding scheme as needed.
