The design begins with a rugged flanged enclosure that comes standard with gold plated XLRs and a removable screw-down barrier strip for easy installation in a NEMA enclosure. Plug and play easy to use, this passive interface does not require any power to work. Inside are two specially designed Jensen audio transformers with extended subsonic response to deliver powerful and articulated bass for maximum impact. Even when being subjected to extremes, the SUB-2XX is able to gracefully handle low frequencies down to 20 Hz with less than 0.01% distortion and less than 1 dB of phase shift. To further optimize the performance, a bottom mounted 8 position ‘set & forget’ dip switch enables the user to configure the SUB-2XX grounding scheme as needed. And with better than 100 dB of common mode noise rejection, you can enjoy the full performance of your audio system without noise.

Simply connect the SUB-2XX between the source and the input destination to eliminate ground loops, electromagnetic interference (EMI) and RFI problems. The SUB-2XX will quietly go to work without introducing distortion, phase shift or artifact of any kind. These combined features make the Iso-Max SUB-2XX ideal for balanced home theater systems, professional studios, PA systems and the most demanding post production facilities.
