Customer Questions & Answers
-
Question:
Can the JDX-48 capture the details of an electric guitar properly?
Answer: Yes, the JDX-48 is specifically designed to capture the guitar's details accurately by deriving its signal from a powered signal from the head. -
Question:
What makes the JDX-48 different from DI built into guitar heads?
Answer: The JDX-48 captures the characteristics that power tubes and solid state power stages lend to a guitar sound, while DI built into guitar heads typically tap the preamp output, missing these characteristics. -
Question:
Is the JDX-48 suitable for bass as well?
Answer: Yes, the JDX-48 is also popular for bass as it delivers clarity and punch in the lower midrange, reminiscent of an Ampeg SVT connected to an 8x10 cabinet. -
Question:
Can I use this to go from the "ext. speaker" jack on a Fender Princeton Reverb into the JDX 48, then from the XLR out on the JDX 48 to the PA?
Answer: Only if you use an external speaker. The JDX 48 needs a speaker load. You could also use a Load Box in place of an actual speaker cabinet. -
Question:
Can the unit be powered with the provided power supply or with mixer supplied phantom power?
Answer: Yes, you can use either one depending on your type of use. If going into an amplifier-to-a mixer board, you can use the phantom power from the mixer. -
Question:
Does it come with a power source or can one be purchased separately?
Answer: Mine came with a 9 volt adapter.
Radial Engineering Direct Boxes R800 1402 Editorial Review
The Radial JDX 48 1-Channel Active Instrument Direct Box has garnered enthusiastic feedback from musicians, particularly guitarists, who appreciate its clarity-enhancing capabilities. Users report that the unit operates seamlessly, significantly elevating the quality of their guitar tones with minimal effort. Musicians find it especially valuable for live performances, where connecting to the front-of-house sound system (FOH) without the hassle of miking a cabinet is a major advantage. The JDX 48 effectively simulates the sound of a mic’d cabinet, providing an impressive tone that translates well through PA systems. Another praised feature is its phantom power capability, enabling ease of use and reducing the clutter of additional power supplies for setups that support it. While the JDX 48 is recognized as ideal for various configurations, users note that it is most effective when paired with head units or combo amps that can be disconnected from their cabinets. This adds versatility for different performance scenarios. Overall, the Radial JDX 48 appears to be a solid choice for musicians looking to simplify their live sound setup while achieving outstanding tonal clarity. **
