Radial EngineeringJDX-48 Reactor Guitar Amp Direct Box
1/8
Independent shopping perspective
The Korena take
A transformer-isolated, Class-A guitar amp direct box designed to capture a powered amp signal with reactive-load speaker emulation and consistent direct tone.
Strong match
Who this is for
- Guitarists seeking a direct signal derived from a powered amp head
- Players using in-ear monitors who want consistent tone between shows
- Bass players who want extended low-frequency response
Consider the trade-offs
When to look elsewhere
- Players who do not need a direct output from a powered guitar amp
- Users seeking an unprocessed, non-speaker-emulated direct signal
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Discrete Class-A, transformer-isolated circuit
The direct output uses discrete Class-A circuitry and transformer isolation.
Detail 03
Bass extension
Lowers the frequency response for bass guitar.
Detail 04
Polarity reverse
Inverts signal polarity at the XLR output.
Final check
Know before you order
- 01It is designed to take its source signal from a powered amplifier.
- 02Its active filter is voiced for 4×12 half-stack cabinet emulation.
- 03Power is supplied by 48 V phantom power or the included +15 VDC/400 mA adapter.
- 04The supplied data states power handling for amps up to 300 W; it also lists a separate 120 W @ 8 Ω maximum-input figure.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What signal does the JDX-48 use?
It is designed to derive its signal from a powered amplifier head rather than a preamp output.
02Does it include speaker emulation?
Yes. Its active band-pass filter emulates the tone of a 4×12 half-stack cabinet.
03Can it be used with bass guitar?
Yes. The supplied data states that it has extended low end for deep bass frequencies and a bass-extension feature.
04How is it powered?
It can use 48 V phantom power or the included +15 VDC/400 mA adapter.
