Radial J-Iso Stereo +4dB to -10dB Converter

Built from the ground up with 100% discrete components, this passive design prioritises signal integrity above all else. The set-and-forget level control allows you to attenuate input signals, preventing overload of your destination device. Multiple output options cater to various setups, including stereo 1/4" connectors, RCA pairs, and a mini 3.5mm output for direct connection to portable recorders or laptop computers.

Transformer isolation technology eliminates the hum and buzz typically caused by ground loops, while simultaneously blocking stray DC currents from affecting your signal path. This passive approach ensures your audio remains clean and uncoloured throughout the signal chain.

The robust construction utilises 14-gauge steel throughout, featuring Radial's distinctive bookend design that creates a protective zone around connectors and controls for enhanced durability. This steel chassis also provides effective shielding for the internal transformers against external magnetic interference. An innovative I-beam skeletal insert prevents PC board torque, reducing stress-related failures and ensuring long-term reliability of solder joints.
