| Content | Radial J-ISO Stereo Isolator
- 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 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.
J-Iso Part # R800-1025: 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.
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.
Designed for full range applications, the J-Iso combines exceptional signal handling with the type of durability that has made Radial famous. | Rackmount PG-X Power Conditioner with PG-90 Filtering Technology, Panasonic and Wima capacitors, eight rear switched, filtered and surge protected outlets, one front-panel switched convenience outlet and USB port for device charging.
