Description
RADIAL J-Iso Balanced +4dB to -10dB unbalanced passive stereo converter, full range. The Radial J-Iso™ and Pro-Iso™ are stereo line isolators designed to convert a professional +4dB line level balanced signal to an unbalanced -10dB consumer level device. This enables you to take the balanced output of a mixer and feed a consumer level recorder or audio input on a computer.
Features
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.
