    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!

    Product 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, 180 degree 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. The single most important development goal of the Radial J48 was increasing the headroom without compromising sound quality. To this end, every possible effort was made to deploy the limited energy resources of phantom power to the audio signal path.To begin, phantom power is converted using a super-efficient digital switch-mode power supply that steps up the internal rail voltage to an impressive 10 volts. This allows one to hit the J48 with as much as 9-Volts without choking! To further increase available horsepower, all non-essential devices such a power-hungry LEDs are turned off when the J48 is in use. A typical LED requires almost as much current as does the complete audio circuit!FeaturesWelded 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
