Brand:: Radial

Main Features

Stereo pro-to consumer audio interface
RCA, 3.5mm and ¼” outputs, XLR inputs
Variable output control to set optimum levels
Transformer isolated to eliminate hum & buzz
Passive design doesn’t need power
‘Plug & play’ easy-to-use anywhere

The passive design begins with 100% discrete components throughout. A set & forget level control lets you attenuate the input signal to prevent it from overloading the destination device. Output connections include a stereo pair of ¼" connectors, a set of RCAs and a mini 3.5mm (1/8") for interfacing to a mini recorder or lap-top computer. Transformer isolation helps eliminate hum and buzz caused by ground loops while eliminating stray DC currents from flowing. Construction begins with 14 gauge steel throughout utilizing Radial's unique bookend construction. This creates a protective zone around the connectors and controls for added durability. The steel construction also assists by shielding the transformers from outside magnetic fields. Inside, the J-Iso features an innovative I-beam skeletal insert that makes it virtually impossible to torque the PC board. This reduces potential stress which could cause premature solder joint failure.

J-ISO has the smart features of the Pro-ISO but with the added sonic excellence of genuine JENSEN audio transformers. Jensen transformers feature nickel cores for high input levels before saturation, Mu-metal shields for protection against electromagnetic fi elds, 100% isolation to eliminate noise caused by ground loops, virtually zero phase shift and they sound great!
