Jensen Transformers DIN-LI Overview

Ideal for use in performance venues, broadcast houses, and broad-scale AV installations, the Jensen Transformers Iso-Max DIN-LI is a passive, single-channel line-input isolator, which prevents and eliminates hum and buzz by isolating the input of the connected device. Designed to work with professional, balanced audio systems, it is also capable of attenuating electromagnetic interference (EMI) and radio frequency interference (RFI) problems. 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-LI features a high-performance Jensen transformer with internal Faraday shield, which eliminates ground loops and reduces common-mode noise by as much as 124 dB. The unit delivers a flat frequency-response from 5 Hz to 40 kHz, and can withstand signals in excess of +19 dB at 20 Hz, without discernible distortion.

Connections to and from the Jensen Transformers Iso-Max DIN-2LI are made via removable screw-down wire terminals. The module comes equipped with a gray, molded assembly made from UL94-VO flame-retardant Noryl.

Key Features

  • Passive, single-channel line-input isolator for professional, balanced audio systems
