SUB-1RR Sub-woofer isolator
The Iso•Max SUB-1RR is a single channel low-frequency isolator designed especially for use with sub-woofers to eliminate hum and buzz caused by ground loops.
- Eliminates hum and buzz caused by ground loops
- Extended low frequency response down to 1 Hz
- Less than 0.01% distortion at 20 Hz
- Plug and play easy to use, no power required
Inside, a specially designed Jensen audio transformer with extended sub sonic response delivers powerful and articulated bass for maximum impact. Even when being subjected to extremes, the SUB-1RR is able to gracefully handle low frequencies down to 20 Hz with less than 0.01% distortion and less than 1° of phase shift. And with better than 100 dB of common mode noise rejection, it solves the most difficult installation problems so that you can enjoy the full performance of your audio system without noise.
Housed in a heavy duty steel enclosure, the SUB-1RR is equipped with a ‘screw down flange’ for easy mounting inside an equipment rack, under a shelf or directly on the sub woofer. Gold plated RCA connecters ensure optimal signal transfer and will not corrode over time. The passive design does not require any power. You merely plug in and it goes to work without artifact or signal degradation. These combined features make the Iso•Max SUB-1RR ideal for home theater, studio and car audio installations.
