DIN-MS-2P Two-way mic splitter (1x2)

The Iso•Max DIN-MS-2P is a passive single channel mic splitter that lets you take a microphone signal and send it to two consoles at the same time.

  • Balanced isolator sends mic signal to two outputs
  • Elimnates hum and buzz caused by ground loops
  • Linear frequency response from 5 Hz to 50 kHz
  • Easy to use DIN rail format for quick installations

The design begins with a gray molded assembly made from UL94-VO flame retardant Noryl that snaps into place onto a standard 35 mm DIN rail for easy installation in a NEMA enclosure. Connections to and from the module are made via removable screw-down wire terminals. Plug and play easy to use, this passive interface does not require any power to work. Inside is a premium Jensen mic bridging transformer equipped with dual faraday internal shields and external MuMETAL® cans. This isolates the mixing console mic inputs eliminating ground loops while reducing common-mode noise by as much as 130 dB.

Made for the most demanding professionals, the DIN-MS-2P delivers a ruler flat response from 5 Hz to 50 kHz with less than 2° phase shift at all frequencies. This makes the DIN-MS-2P ideal for isolating or distributing mic signals in performance venues, broadcast houses and broad scale AV installations.

Applications

DIN-MS-2P Splitting a mic signal

The Jensen DIN-MS-2P is the perfect interface for splitting a microphone to feed more than one mixer at the same time. 100% isolation eliminates potential ground loops between the two consoles for quiet performance. The main thru-put provides a 48V phantom power return path for condenser mics or active direct boxes.
