Product Overview

Many typical active direct boxes can't handle the load of a electric keyboard or a battery-powered guitar or bass, which can get as hot as 7 volts. However, the Radial Engineering J48 Stereo is not only a great sounding active direct box, it's been optimized to produce maximum headroom while working within the limited current available from standard 48V phantom power. By employing a unique switching power supply, the J48 is capable of peak transients to 9 volts without choking. The result is lower harmonic distortion, half the inter-modulation distortion and significantly improved dynamics over other DIs.

Several switches are available to help clean your sound and make the direct box more versatile. A ground lift eliminates buzz from ground loops, while the high pass filter switch removes unwanted boomy bass response. Finally, the 15dB pad helps cool off signals that would otherwise be too hot to handle!

The compact J48 Stereo is built road-ready with 14 gauge steel in our unique book-end design that provides protective zones around the switches and connectors. The internal welded I-beam construction assures outside stress will not torque the PC board thus assuring longer product life.

You've probably already heard great thinks about Radial's infamous J48 direct box; the J48 Stereo offers all of the same qualities but suited for stereo instruments! Grab yours today to own the quality direct box Radial is known for.
