Jensen Transformers DIN-LOF Overview

Ideal for use in performance venues, broadcast houses, and broad-scale A/V installations, the Jensen Transformers Iso-Max DIN-LOF is a passive, single-channel line output isolator designed to drive balanced and unbalanced audio signals over long distances, while eliminating hum caused by ground loops. The unit is plug-and-play with no power required, and snaps into place onto a standard 35mm DIN rail, for easy installation in a NEMA electrical enclosure.

The DIN-LOF features a high-performance Jensen transformer with internal Faraday shield that isolates the input from the output to reduce common-mode noise by as much as 94 dB. Furthermore, a choice of connection point options allows you to optimize the grounding circuitry to suit your specific installation needs. The unit is capable of withstanding input levels in excess of +21 dB at 20 Hz, without discernible distortion. It delivers an extra-high output level of +21 dBu with a flat frequency response from 10 Hz to 50 kHz.

Connections to and from the Iso-Max DIN-LOF are made via removable screw-down wire terminals. The module comes equipped with a gray molded assembly made from UL94-VO flame-retardant Noryl.
