    New Top-Brand Gear From An Authorized US Dealer

    You get top-brand gear, new from the factory, from an authorized US dealer. Our products are shipped from the vendor to our warehouse, and then from the warehouse to you. There is no detour through a retail store, where the boxes are opened, the products put on display, and then sold as leftovers. When you shop online, make sure you are comparing new gear from authorized US dealers. 

    Special Opportunities: When It's Not New, We Tell You

    We occasionally have opportunities to buy B-stock merchandise to offer at special discounts. We also sometimes get returns in less than perfect condition. Sometimes we will offer these products to you - but we always identify it clearly as such using the classifications below. So unless it says otherwise, it's new from the factory.

    Important Guarantee: Your 100% Satisfaction

    Regardless of the condition described on our site, what you should remember is that if you are not 100% satisfied with your purchase you may return it (though exceptions apply for some products). Of course, if you know you will only be happy if a product is 100% cosmetically perfect, then you shouldn't order B-Stock or Blemished merchandise - it's just not a good gamble. And if you will only be happy if a product has never been touched by another human, well then the Resealed products aren't a good choice for you. But if you are looking for even more impressive values than our already-low prices, then these options will be very attractive when available.

    These are our best descriptions of the quality and condition of this merchandise. Because of the highly efficient, automated nature of our warehouse, and the high volume of products we stock and ship, there is no way for us to provide any additional detail on the condition of any individual item. Just remember our 100% satisfaction guarantee!

    Warehouse Resealed

    A warehouse resealed product is usually a customer return. These products are not in absolutely new condition, but will ship with everything the brand new product would ship with including manuals* and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    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! These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    Scratch and Dent

    This is typically a customer return that shows general wear and tear, along with dents and scratches. 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, but will show signs of use. It may be less attractive than Blemished inventory, but it's priced even lower! These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    Factory Resealed

    A factory resealed product is purchased directly from its manufacturer, who may have refurbished the product or used it for training and demonstration purposes. These products are not in absolutely new condition, but will ship with everything the brand new product would ship with including manuals (physical copy or downloadable) and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 

    B-Stock

    A B-stock product is purchased directly from its manufacturer, who may have refurbished the product or used it for training and demonstration purposes. These products may be cosmetically blemished, but will ship with everything the brand new product would ship with including manuals (physical copy or downloadable) and the full factory warranty*. These products are still covered by our 30-day satisfaction guarantee, so they're a great deal! 


    *Warranty coverage for non-new gear varies by manufacturer. To see if the non-new product you’re interested in has warranty coverage, click the "What is Blemished/Warehouse Resealed/etc." text link near the price on the product page.

    Product Description


    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
    - Twice as good as the world's finest phantom-powered active DI!
