Stemming from the adage 'necessity is the Mother of invention', the J-Rak was invented, to provide sound companies with a simple yet very functional solution for DI inventory management. The problem is simple: During peak season, most sound companies must resort to cross-renting just to fill rider requests. Inevitably, they go to a warehouse looking for a stand-alone DI and find that all that is left on the shelf are a few old 4-channel rack units. Or conversely, they have a show going on the road that needs 12 rack-mounted DIs but the investment seems impractical.

All you do is take the book-end cover off the JDI or J48 and attach one of the 8 insert sleeves supplied with the J-Rak. These are then screwed into the J-Rak shelf from the top. The direct boxes can have the XLR facing either the front or the rear of the rack depending on the application; whether one is racking up DIs for keyboards, sound modules, computers or other sound sources.

Radial J48 Features:

• Active 48-Volt phantom powered direct box
• Minimal power draw with high rail voltage
• Will not choke when driven hard
• Low inter-modulation distortion

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 JDI Features:

• Jensen Transformer equipped passive DI
• 100% isolation eliminates ground loops
• Virtually zero phase & harmonic distortion
• Exceptional signal handling
• High common mode noise rejection

The Radial JDI is considered by many to be the world’s finest direct box. It is a passive DI that employs a Jensen isolation transformer for optimum audio performance offering outstanding linearity at all frequencies, combined with extraordinary level handling without introducing distortion. Being completely passive, the plug & play JDI does not require any powering and has the unique advantage of eliminating 60-cycle ground loops. This makes the JDI a definite favorite with informed audio engineers. The JDI is great for guitars, bass, and keyboards and is particularly adept with high-output, broadband instruments such as active instruments and digital keyboards. The JDI may be rack-mounted using the J-Rak and is also available in a stereo (2-channel) version called the JDI Duplex and the 6-channel rack-mountable JD6.
