Brand: Radial

The Radial J48 Stereo is a high-performance active direct box designed for professional touring and studio recording. It features the same award-winning signal path that has made the single channel J48 the most specified active direct box on tour today. And with users as diverse as Paul McCartney, Tommy Emmanuel and Joe Chiccarelli, you can be sure it will meet the most demanding qualifications.The design begins with a rugged 14-gauge steel construction and a bookend design that protects sensitive switches and connectors from damage. The internal I-beam construction ensures the fragile internal PC board will not torque, which in turn could lead to cold solder joints developing and premature failure. All connectors are made from glass-filled nylon and feature extra-large nickel-silver contacts that will not tarnish over time.Inside, a unique switching power supply converts the 48 volt phantom to AC, increasing the headroom for improved signal handling and lower distortion. This results in an exceptionally linear frequency response that spans from 10Hz to 40 kHz while being able to handle high output instruments without choking. In addition, a -15dB pad may be engaged for extreme signal handling. This is supplemented with a high-pass filter that gently rolls off low frequencies below 80Hz to clean up mud and excessive resonance. A side-access 180o polarity reverse aids when using the J48 Stereo with dual element pickups to either phase align the sources or eliminate acoustic hot spots that can cause feedback on stage.A unique aspect of the power supply is the way that the J48 handles buzz and hum caused by ground loops. The traditional solution is to lift the audio ground by disconnecting pin-1 at the XLR output. When this is done, the 48-volt phantom power from the console is shut off, forcing one to introduce a battery into the equation. Unfortunately, batteries are inconsistent, and when they begin to drop power, severely affect the available voltage and resulting headroom. Instead, the J48 employs a DC to DC converter with a high frequency transformer that enables the audio ground to be lifted at the power supply. This does not shut off the phantom power and is invisible to the user.The Radial J48 Stereo

New Products
Brand-new products are shipped from the vendor's factory to our warehouses, then from the warehouse to you – there's no detour through a retail store where the boxes are opened, and the products put on display and sold as leftovers. When you shop online, make sure you're comparing new, factory-fresh gear from authorized US dealers like zZounds.

Clearance Gear: Special Opportunities to Save Big!
When It's Not New, We Tell You
We occasionally have opportunities to buy B-stock merchandise from manufacturers. And sometimes, we get customer returns in less than perfect condition. We offer these products to you at special discounts – and we always identify it clearly using the classifications below. So unless it says otherwise, your product is new from the factory.

Warehouse Resealed
Warehouse Resealed gear is typically a customer return. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*. However, the packaging may be slightly compromised and thus not in absolutely perfect, unused condition like our new inventory. This inventory is a great value.

Blemished
This is typically a customer return with minor cosmetic imperfections, such as superficial scratches or scuffs on the finish. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*. It has been tested to manufacturer's specifications and is guaranteed to work perfectly. It may be less attractive than Warehouse Resealed inventory, but it's priced even lower!

This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*.

Factory Resealed
Factory Resealed gear is typically a purchase directly from the vendor, who may have used the product at a training session or at a trade show. It may also be a factory-refurbished product. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*. However, the packaging may be slightly compromised and thus not in absolutely perfect, unused condition like our new inventory. This inventory is a great value.

B-Stock
B-Stock gear is typically a purchase directly from the vendor, who may have used the product at a training session or at a trade show, or it may be a refurbished product. This inventory includes all parts, components, manuals (hard copy or downloadable) and the full factory warranty*. It has been tested to manufacturer's specifications and it is guaranteed to work perfectly, but it may have a cosmetic blemish.
