Radial Engineering JDX 48

The Radial JDX 48 is an active guitar amp direct box (DI) designed to capture the sound of a guitar or bass amplifier with incredible accuracy, while maintaining the warmth and character of the tone. It's widely used for both studio recording and live performances, offering a natural, amp-like sound without the need for miking the speaker cabinet.

Key Features:
Active Direct Box:

Requires 48V phantom power to operate, making it compatible with mixing consoles or audio interfaces that supply phantom power.
Amp and Speaker Capture:

The JDX 48 connects between the amp head and the speaker cabinet, capturing the true tone of the amplifier along with the natural response of the speaker.
Frequency Response:

Designed to emulate the response of a 4x12" guitar cabinet, producing warm, smooth mids and punchy lows, perfect for guitar and bass.
Cabinet Simulation:

Built-in proprietary cabinet emulation circuit that delivers the sound of a mic’d cabinet directly to the PA or recording console without the need for an actual mic.
Passive Amp Through:

Pass-through connection sends the signal to the speaker cabinet for real-time monitoring, while the balanced output feeds the mixing console.
Specifications:
Input:

1/4" speaker input from amplifier head (max input 300W RMS).
Output:

1 x balanced XLR output for direct signal to mixing console or audio interface.
1 x 1/4" thru output to send the signal to the speaker cabinet.
Frequency Response:

Flat response from 20Hz to 20kHz with gentle filtering for a natural, amp-like sound.
Ground Lift Switch:

Eliminates hum or buzz caused by ground loops.
Phantom Power:

Requires 48V phantom power from a mixing console or preamp to power the unit.
Impedance:

XLR output impedance: 600 Ohms
Thru impedance: 8 Ohms
Applications:
Live Sound:
Provides a consistent guitar or bass tone to the front-of-house engineer without the hassle of mic placement.
Recording:
Ideal for direct recording of guitar and bass amplifiers, capturing the full character of the amp and speaker while minimizing bleed from other instruments.
Bass Guitar:
Equally effective for bass, providing deep, punchy lows and clarity in the mids and highs.
Build Quality:
Durable Design:
Built with heavy-duty 14-gauge steel for rugged performance and long-term durability.
Compact Size:
Small enough to fit in a pedalboard or gig bag, making it a convenient solution for both studio and live use.
Ideal For:
Guitarists and Bassists:
Ideal for players who want to achieve a consistent, mic-free tone for live or studio environments.
Sound Engineers:
A reliable tool for getting clean, direct amp signals without the hassle of mic placement, room acoustics, or phase issues.
The Radial JDX 48 is a powerful solution for capturing the sound of a guitar or bass amplifier with clarity and warmth, making it a must-have for musicians and sound engineers alike.
