Radial Engineering J48 Stereo – Active Two-Channel DI with High Headroom & Phantom Power

The Radial Engineering J48 Stereo is a premium active direct box designed for dual-mono or stereo instruments that demand exceptional clarity, headroom, and low distortion. Built on the foundation of Radial’s renowned J48, this stereo version uses a unique switching power supply driven by 48V phantom power to achieve greater dynamic range and transparency than typical active DIs. Ideal for keyboards, acoustic instruments, bass, and high-output active pickups, the J48 Stereo delivers pristine, phase-accurate sound on stage and in the studio.

Key Features

  • Phantom-powered active design: Innovative power supply maximizes headroom and minimizes distortion.
  • Stereo / dual-mono operation: Perfect for keyboards, drum machines, and stereo acoustic rigs.
  • Rugged 14-gauge steel construction: Radial’s bookend design protects switches and connectors on the road.
  • High-pass filter & pad: 80 Hz HPF clears rumble; -15 dB pad handles hot signals.
  • Ground lift & polarity reverse: Tools for eliminating hum, buzz, and phase issues.

Customer Benefits

The J48 Stereo captures every nuance of your instrument with clean, accurate detail—even at high volume.
