Jensen Transformers SUB-1RR Overview

The Jensen Transformers Iso-Max SUB-1RR Single-Channel Subwoofer Isolator is a passive, unbalanced, and mono low-frequency isolator which prevents and eliminates hum and buzz caused by ground loops in subwoofers. It ensures that your music's low-end is faithfully delivered without distortion, coloration, or artifact when used with audiophile systems, home theaters, car audio installations, and more.

The SUB-1RR features a high-performance Jensen transformer which rejects noise by as much as 100 dB, and handles low frequencies down to 20 Hz with less than 0.01% distortion. It also extends your program' subsonic response down to 1 Hz, for maximum bass impact.

Easy to set up with no power required, the Iso-Max SUB-1RR comes with gold-plated RCA connectors that ensure optimal transfer of the audio signal. The unit is equipped with a rugged steel enclosure and fitted with screw-down flanges for mounting inside a rack, under shelves, or directly on the subwoofer.
