The Radial Engineering J48 Stereo is a high performance, stereo, active direct box designed for professional touring and studio recording. It features the same award-winning signal path that has made the single channel J48 the most specified active direct box on tour today. 

The design begins with a rugged 14 gauge steel construction and a bookend design that protects sensitive switches and connectors from damage. The internal I-beam construction ensures the fragile internal PC board will not torque, which in turn could lead to cold solder joints developing and premature failure. All connectors are made from glass-filled nylon and feature extra large nickel-silver contacts that will not tarnish over time.

Inside, a unique switching power supply converts the 48 volt phantom to AC, increasing the headroom for improved signal handling and lower distortion. This results in an exceptionally linear frequency response that spans from 10Hz to 40kHz while being able to handle high output instruments without choking. In addition, a -15dB pad may be engaged for extreme signal handling. This is supplemented with a high-pass filter that gently rolls off low frequencies below 80Hz to clean up mud and excessive resonance. A side-access 180º polarity reverse aids when using the J48 Stereo with dual element pickups to either phase align the sources or eliminate acoustic hot spots that can cause feedback on stage.

Key Features:
