Radial J48 Stereo Phantom Powered Active Direct Box

The J48 Stereo is a high-performance two-channel active direct box engineered for live concert touring and professional recording studio applications. Unlike typical active DIs that overload at 3 volts, the J48 Stereo employs a unique switching power supply that raises internal rail voltage to handle up to 9 volts, providing exceptional headroom for battery-powered instruments and stereo keyboards that can produce 7 volts at maximum output. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of instruments to pass through unaltered. Powered exclusively by 48V phantom (no batteries required), the J48 Stereo maintains excellent stereo separation and low crosstalk between left and right channels, making it equally suited for stereo sources like keyboards or dual mono applications with two separate instruments. A built-in pad reduces sensitivity when needed, while the compact design delivers sound quality rivaling DIs costing five times as much.

Key Features:

  • Exceptional 9-Volt Headroom: Unique switching power supply raises internal rail voltage to handle up to 9 volts, preventing overload from high-output battery-powered instruments and digital keyboards that produce up to 7 volts.
  • Ultra-Low Distortion Performance: Additional headroom significantly reduces distortion of all types, preserving the natural tone and character of instruments without coloration or compression.
  • True Stereo Operation: Maintains excellent stereo separation and low crosstalk between left and right channels for accurate reproduction of stereo keyboards, synthesizers, and sample players.
  • Dual Mono Capability: Connect two completely different instruments (bass and acoustic guitar, fiddle and mandolin, two basses) through a single compact direct box with independent channel performance.
  • 48V Phantom Powered: Operates exclusively on phantom power from mixing console or preamp, eliminating battery replacement and ensuring consistent performance throughout long sessions or tours.
  • Built-In Pad: Reduces input sensitivity when connecting extremely hot sources, providing additional signal management flexibility across diverse instruments and output levels.
