The Radial JDI Stereo is a passive stereo direct box designed for musicians, sound engineers, studios, and service providers seeking flawless audio transmission. It handles very high signal levels without clipping and operates without a power supply. Thanks to its Jensen transformers, it guarantees a natural, noise-free signal that is perfectly suited for long audio runs. It sets the standard for discerning users who prioritize sound quality and reliability.

Features

A passive design capable of handling the most powerful signals

The JDI Stereo requires no external power supply. Its Jensen audio transformers directly provide signal balancing and impedance matching. You can connect high-level sources without risk of distortion, even in the most demanding setups.

The natural sound of Jensen transformers

Jensen transformers are renowned for their excellent handling of transients and their particularly musical sound reproduction. You retain the full dynamics of your instrument with smooth highs, deep lows, and a faithful reproduction that evokes the character of vintage high-end audio equipment.

Audio quality preserved over long distances

The low-impedance conversion allows for the use of long cable runs without any loss of quality. With a frequency response of 10 Hz to 40 kHz and perfectly controlled phase, the JDI Stereo reproduces the original signal with great transparency.

Effective protection against interference

The transformers also provide galvanic isolation between the input and output. They eliminate unwanted DC voltages and effectively reduce ground loops. The Ground Lift switch complements this protection to eliminate hum and noise in complex setups.

Connectivity Designed for Professional Applications

Each channel features a jack input with a -15 dB attenuator to handle high output levels. The balanced XLR outputs facilitate integration into all professional mixing consoles and sound reinforcement systems.

A build designed to last

The rugged steel enclosure effectively protects the electronics during transport and live performances. Combined with the mu-metal transformer shields, it acts as a Faraday cage to minimize electromagnetic interference caused by amplifiers or other electrical equipment.
