MS-2XX Two channel mic splitter

269.99 Request

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

  • Stereo isolator sends mic signal to two outputs
  • Delivers exceptionally low distortion down to 20 Hz
  • Ruler flat frequency response from 5 Hz to 100 kHz
  • Plug and play easy to use, no power required

The design begins with a rugged flanged steel encloser for easy mounting in a rack or inside a NEMA enclosure. Standard gold plated 3-pin XLR-female inputs and XLR-male isolated outputs. Removable screw-down terminal block as a direct output and phantom power return for condenser mics. Inside are two premium Jensen mic bridging transformers equipped with dual Faraday internal shields and external MuMETAL® cans. These isolate the two consoles, eliminating ground loops while reducing common-mode noise by as much as 130 dB. This is augmented with a 8 position DIP switch that lets you optimize grounding and RF filtering to suit your specific installation needs.

Made for the most demanding professionals, the MS-2XX delivers a ruler flat response from 5 Hz to 100 kHz with less than 2° phase shift at 20 Hz. This makes the MS-2XX ideal for isolating or distributing mic signals in recording studios, broadcast houses and performance venues.

Applications

MS-2XX with dynamic mics

To eliminate noise, isolate your microphones using the XLR-female inputs and send the output to your mixing console via the XLR-males. For mic splitting, use the screw-down terminal block as a direct out. This also lets you pass 48V phantom for condenser microphones.
