Ideal for use in performance venues, broadcast houses, and broad-scale AV installations, the Jensen Transformers Iso-Max DIN-2LI is a passive, 2-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-2LI features a pair of high-performance Jensen transformers with internal Faraday shields, which eliminate ground loops and reduce 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, 2-channel line-input isolator for professional, balanced audio systems
  • Isolates the input of the connected device
  • Connects between the source and the input destination to eliminate hum and buzz caused by ground loops
  • Reduces electromagnetic interference (EMI) and radio frequency interference (RFI) problems
  • Snaps into place onto a standard 35 mm DIN rail for easy installation in a NEMA electrical enclosure
  • Two Jensen high-performance transformers with internal Faraday shields improve rejection of high-frequency buzz by a factor of 100 to 1000 (40 dB to 60 dB) over traditional transformers 
  • Ruler-flat frequency-response from 5 Hz to 40 kHz 
  • Handles signals in excess of +19 dB at 20 Hz, without discernible distortion 
  • Rejects noise by as much as 124 dB
  • Connections to and from the module are made via removable screw-down wire terminals
