Jensen Transformers' Description The SUB-1RR does not include any cables, but if you need them, we have some very high-performance subwoofer In order to insert the SUB-1RR into your signal path, and you may want to consider upgrading your existing cable(s)Īs well. You will need at least two short patch cables Good cables are very important in the fight against hum and noise. That one can install in an audio system that can do so much with so little effort. Immediately, the effects of the ground loop become a non-issue. 0dB insertion loss with 600 Ohm source and 47k Ohm load.Extremely low distortion: 0.01% at 20Hz and -10dBV.Extended low frequency response: -1dB at 0.4Hz, -3dB at 0.15Hz.Common-mode ground noise rejection of 105 dB at 60 Hz.Eliminates the inherent ground noise coupling mechanism.The receiver or preamp LFE output and the sub-woofer input and it immediately provides these benefits: Just insert it anywhere in the audio line between The Jensen Transformers SUB-1RR is elegant in its simplicity. Ground loops can occur in a mobile installations as well, because all of theĪmplifiers in the system have their own internal power supplies, and voltage drop percentages in a 12 volt systemĬan be even more challenging than in a home system. Ideally, ground loops would be prevented at the design level, but if you are working with an existing room, it Other, or any number of other reasons that are beyond the scope of this article. ItĬan be because one of the circuits is loaded more heavily than the other, or because one run is longer than the The result is that the neutral or ground side of the two circuits can be at a slightly different potential. It's easy to understand why, because the sub-woofer may be across the room,Īnd/or it may require so much power that a single branch circuit just isn't enough to handle the load. Ground loops are often the result of the fact that sub-woofers tend to be powered by a different electrical branchĬircuit than the rest of the A/V system. Loops can induce enough hum on the input to keep the amplifier running continuously. Most powered sub-woofers use a signal-sensing circuit to turn the amplifier off when no signal is present, but ground This hum is most often heard in powered sub-woofers, but may also be present in the main channels as well. When ground loops happen, the result is unwanted Ground loops can happen even in the most carefully planned A/V system. It is a subject that is seldom discussed in manufacturers publications, or even in magazines of the trade, but Ground Loops? (or why the best planned systems sometimes sound bad) The SUB-1RR is made in the USA, is backed by the manufacturer'sĬomprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself. The USA, and we are proud to be able to offer their products. Jensen Transformers, actually designing and manufacturing some of the finest products in the world, right here in With inferior products coming from all over the world, we think it is a genuine treasure to find a company like They solve the fundamental problems associated with ground loops, Jensen Transformers' ISO-MAX Studio-Quality Audio Isolators provide SUB-1RR with similar (but inferior) products. If you're not sure which model to choose, please check out our The flanges have mounting holes, which are handy for W x 2.6" D x 1.45" H., including the flanges. The SUB-1RR is housed is a sturdy metal enclosure, measuring 3.63" The zero dB insertion loss also prevents carefullyĬalibrated system levels from being disturbed. Solve even the most difficult subwoofer installation problems. In this unit provides unparalleled low frequency response while providing over 100dB of common mode isolation, to The Jensen Transformers ISO‑MAX SUB‑1RR Low Frequency Audio Input Isolator is designed specificallyįor subwoofer amplifier isolation in home theater and automotive applications.
