Radial Engineering J48 Description
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 inter-modulation distortion and significantly improved
dynamics over other DIs.
Features
include a -15dB pad, 180º polarity reverse, a unique merge function to mix two
signals to mono, an 80Hz high-pass rumble filter, and ground lift. Like all Radial
products, the J48 is built to handle the abuse on the road and features a
unique welded I-beam construction for years of trouble free performance.

Radial J48 Review /
See All ZenPro Audio Reviews Here: Review Page
The J48 is a phantom powered preamp,
accepting instrument levels and converting to balanced microphone levels for
mic preamp gain. The feature set is great: -15dB pad, polarity reverse, ground
lift, merge (takes 2 inputs to 1 output) and a high pass filter. It is great
for sending a long run instrument output to the mixer’s preamps without induced
noise or distortion.
The J48 is super clean, and somewhat
brighter than passive models and very detailed sounding. When you do not want
to alter the source’s sound and are driving a long cable run, this active box
delivers the goods if you’ve got the phantom power it needs. No noise, no
issues, and the build is so sturdy you could likely toss it off a building and
fire a bullet at it and it will still hold up.
Conclusion: Recommended for taking
passive outputs (or active) and sending them over long distances in a clean,
uninterrupted way!
