Radial J48 Phantom powered DI box £146.80
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.

Technical Specifications
- Welded I-beam construction makes it impossible to torque the PC board. This virtually eliminates cold solder joints - the No.1 cause of system failure in the field.
- An innovative ‘slide-in-place’ XLR trace makes it possible to use I-Beam girder construction.
- A digital switching power supply steps-up the internal rail voltage to 9-Volts. The J48 will not choke like other DI’s when hit with large transients.
- A military-grade PC board is employed for maximum wear and tear in abusive environments. Welded steel standoffs ensure the PC board will not shift.
- A -15dB pad allows super hot inputs such as that from a CD player to be connected and balanced for long runs.
- Momentary 48V Check LED will flash once when the 80Hz filter is depressed to tell you phantom power is present.
- The Merge function turns the input & thru into ‘left & right’ inputs to mono mix at the XLR output. This handy function saves valuable inputs on the mixer!
- The input is connected to the instrument.
- The thru-put is connected to the instrument amplifier. The JDI has a high input impedance to reduce loading.
- Our book-end design creates a protective zone around the switches & connectors for best protection!
- A heavy-duty baked enamel finish for excellent durability and great looks for years! 100% 14-gauge steel construction.
- The 600 Ohm balanced XLR out is mic level to properly match concert splitters - will drive 1000 feet without appreciable noise.
- A polarity reverse switch flips the polarity from the AES standard Pin-2 to Pin-3 on the XLR and is used when combining sounds that may be out of phase.
- An 80Hz low-cut (high-pass) filter gently reduces excessive bass for more headroom and clarity. Eliminates run-away resonant feedback from acoustics!
- The ground-lift disconnects the ground path to the transformer at the XLR output. This is used when a ground path is made at the input side such as with a keyboard.
- A no-slip full bottom pad reduces mechanical vibration, improves electrical isolation and keeps the JDI from moving around on busy stages!
