The Radial J-Iso stereo line isolator uses a premium Jensen transformer to convert a +4dB line level balanced output to an unbalanced -10dB input, allowing you to send a balanced pro-level mixer signal to a consumer-level recorder or computer audio.

  • Converts balanced line level signals to unbalanced
  • Stereo signal path with set & forget level control
  • Transformer isolated to eliminate hum & buzz
  • J-Iso features Jensen™ transformers for optimal signal path

The passive design of the Radial J-Iso Stereo Line Isolator 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.

The J-Iso employs a premium Jensen transformer for optimal signal transfer to minimize distortion and artefact. Full bandwidth performance makes the J-Iso ideal for music production.

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.

Designed for full range applications, the J-Iso combines exceptional signal handling with the type of durability that has made Radial famous.
