Music Interface Technologies MIT z-ISO DUO power conditioner $1,495 Retail.MIT Z-Cord 2 Meter Length Power cordSee the photos for details. The Spectral DMC-20 and other equipments in the photos other than this listing are NOT INCLUDED IN THE SALE!MiT Z-iso Duo spec: Excellent working condition, perfect cosmetics.It contains TWO isolation transformers inside, with over-voltage protection, surge protection, noise filtering.Measures 17 x 5.5 x 11.5 Weighs 35 poundsIf all your components were plugged into one AC power outlet, everything would be fine. As soon as you plug your various components into different outlets, though, the grounds may not all be at the same ground “potential”. Even worse, many cable systems are not perfectly grounded, so they may have a very high “potential” on them. This will result in “buzz” or “hum” in your speakers, and/or “hum bars” that slowly move up your TV screen and drive you crazy! A great solution is to use an isolation transformer. This device has two of them inside, each with “bank” of two AC power outlets. Each of the AC outlet banks can handle 130 Watts. It will help filter noise from your AC line, and will protect your equipment from over-voltages which can burn them out. It also has built-in surge protection. It also isolates the two AC outlet banks on its rear panel FROM EACH OTHER, which few other similar devices do. As a bonus, it’s drop-dead gorgeous, unlike almost all other power isolation devices which tend to be very...shall I say...utilitarian. Please note that this is not just a FILTER or CONDITIONER, but an ISOLATION TRANSFORMER (times 2) in the true sense of the word.
