Overview

Increased headroom, uncompromising sound.

The Radial J48 is a great-sounding active direct box that has 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 intermodulation distortion and significantly improved dynamics over other DIs.

Features include a -15dB pad, 180 degree polarity reverse, a unique merge function to mix 2 signals to mono, an 80Hz high-pass rumble filter, and ground lift. Like all Radial products, the J48 is built to handle abuse on the road and features a unique welded I-beam construction for years of trouble-free performance.
