    Jensen SUB-1RR Low Frequency Audio Isolator (RCA)

    Manufacturer: Jensen Transformers

    Item #: JEN-SUB1RR   •   MFG #: JEN-SUB1RR







    The specially designed transformer in this unit provides unparalleled low frequency response while providing over 100dB of common mode isolation, to solve even the most difficult sub-woofer installation problems. The zero dB insertion loss also prevents carefully calibrated system levels from being disturbed.

      • Extended low frequency response: -1dB at 0.4Hz, -3dB at 0.15Hz
      • Extremely low distortion: 0.01% at 20Hz and -10dBV
      • 0dB insertion loss with 600 Ohm source and 47 kOhm load

      Comments about JENSEN TRANSFORMERS Jensen SUB-1RR and SUB-2RR Low Frequency Audio Isolator:

      Tried to tame subwoofer hum in the notoriously hummy Sunfire True Subwoofer. It reduced the hum by 9 dbs, but there was enough left over to persuade me it was not worth keeping. So I returned it.
