Jensen Transformers MS-2XX overview

  • 1Description

Designed for use in recording studios, broadcast houses or performance venues, the Jensen Transformers Iso-Max MS-2XX is a passive, two-channel mic splitter that lets you distribute a microphone signal to two consoles at the same time, while attenuating radio frequency interference (RFI) such as AM radio broadcast frequencies.

The MS-2XX features two premium Jensen mic bridging transformers, which eliminate ground loops and reduce common-mode noise by as much as 130 dB. An 8-position DIP switch lets you optimize grounding and RF filtering to suit your specific installation needs. The unit delivers a flat frequency-response from 5 Hz to 100 kHz, with low distortion down to 20 Hz. It also passes 48V phantom power for use with condenser microphones.

Easy to set up with no power required, the MS-2XX is equipped with a rugged, flanged-steel enclosure, gold-plated XLR connectors, and is well suited to stand up to the rigors of live use.
