Radial Engineering J48 Phantom Powered Stereo Active DI Box ( R800-3002-00 )

The Radial J48 is a high-performance active direct box designed for both live concert touring and professional studio recordings. Known for its ability to handle extreme transients without distortion, the J48 ensures that the natural tone of your instrument is preserved, providing exceptional clarity and fidelity.

Key Features:
  • Unmatched Headroom: The J48 boasts an internal rail voltage of 9 volts, offering significantly more headroom compared to standard DIs. This allows it to handle loud transients without clipping, keeping your sound full and natural.
  • Phantom-Powered: Powered directly by 48V phantom power—no batteries needed—making it convenient for both studio and live environments.
  • Dynamic Range: Optimized to operate efficiently with the 5 milliamps available from standard phantom power, the J48 delivers superior dynamic headroom, ensuring that your instruments sound clear and powerful.
  • Versatile Controls: Includes a low-cut filter, -15dB pad, and polarity reverse switch to provide maximum flexibility in managing your audio signal.
  • Merge Switch: Easily sums stereo signals to mono, making it ideal for stereo instruments like keyboards or dual-pickup guitars.

Applications:
Perfect for active acoustic guitars and basses, capturing their true sound without distortion.
Works beautifully with keyboards, drum modules, and any instrument prone to producing high transients.
Equally suitable for both live performances and studio recordings, providing consistent and reliable sound quality.

The J48's advanced switch-mode power supply efficiently boosts the internal rail voltage, resulting in richer tones and more natural harmonics.
Durable build quality and backed by a 3-year transferable warranty, ensuring long-term reliability.

Whether you are on stage or in the studio, the Radial J48 offers the exceptional clarity, enhanced headroom, and dynamic response you need to bring out the best in your music. No more choking on transients—just pure, unadulterated sound every time.
