DIN-LI Line input module

139.99 Request

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

  • Eliminates hum and buzz caused by ground loops
  • Delivers exceptionally low distortion down to 20 Hz
  • Ruler flat frequency response from 5 Hz to 40 kHz
  • Plug and play easy to use, no power required

The design begins with 35 mm DIN rail molded in gray UL94-VO flame retardant Noryl format that snaps into place for easy installation in NEMA enclosures via removable screw-down wire terminal. Plug and play easy to use, this passive interface does not require any power to work. Inside is a Jensen high performance transformer that is able to withstand signal levels to +19 dB @ 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. To further optimize the performance, a choice of connection point options enable the user to determine the most appropriate grounding scheme to suit the installation.

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

Applications

DIN-LI with a PA system

Eliminating noise in a PA system can sometimes take hours of trouble shooting, particularly when the mixer, amplifiers and speakers are distanced apart. Simply connect the DIN-LI at the input of your amplifier to instantly eliminate ground loop hum and buzz.

DIN-LI Isolating subs

The use of sub woofers in a PA system has become common in most touring setups. Use the DIN-LI to isolate the sub-woofer amplifier racks to eliminate ground loops without affecting the audio signal path. The DIN-LI is able to withstand tremendous signal levels without distortion.

DIN-LI in the studio

Recording and broadcast studios require a noise-free signal transfer while delivering the most accurate sound possible. The Iso•Max DIN-LI eliminates ground loops and lowers RF without introducing distortion, phase shift or artifact.
