Description

Radial J48 Stereo Active DI Box Hire

The Radial J48 Stereo is a high performance 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.

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.

A unique aspect of the power supply is the way that the J48 handles buzz and hum caused by ground loops. The traditional solution is to lift the audio ground by disconnecting pin-1 at the XLR output. When this is done, the 48 volt phantom power from the console is shut off, forcing one to introduce a battery into the equation. Unfortunately, batteries are inconsistent, and when they begin to drop power, severely affect the available voltage and resulting headroom. Instead, the J48 employs a DC to DC converter with a high frequency transformer that enables the audio ground to be lifted at the power supply. This does not shut off the phantom power and is invisible to the user.
