    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!

    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 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.

    Product Description


    The Radial PZ-DI is a unique direct box that is specifically designed for acoustic and orchestral instruments. Unlike most direct boxes that are limited to a 'one size fits all' design, the PZ-DI lets you properly match the input impedance to the source to optimize the frequency response, dynamics and feel so that no matter what type of pickup you employ, you will enjoy smoother, more musically pleasing results. The design begins with a 3-position load adjustment switch: The 1 meg-ohm position delivers the classic impedance found on most active DI boxes. The 220k-ohm setting warms up the tone of a magnetic pickup to give you the feel and tone as if connected to a tube amplifier. The ultra-high 10 meg-ohm impedance is used to compensate for the harsh, squawky tone that usually plagues piezo-equipped instruments. This is followed by a fully variable high-pass filter that lets you 'size the instrument' by gently rolling off bass frequencies to eliminate unwanted resonance. You could for instance, retain the low frequencies on a cello or increase the cut-off point to better suit a violin. For active instruments such as acoustic guitars that incorporate a battery powered preamp, you can engage a low-pass filter to gently soften the hard edge for a smoother more natural tone.To maximize signal handling and reduce distortion, the PZ-DI incorporates an innovative DC to DC switching supply that converts the phantom power to deliver extra headroom. This provides ample dynamic range for acoustic instruments. Should an extra loud source such as an active bass or digital keyboard be encountered, simply activate the -15dB pad to satisfy the situation. Other problem solvers include a 180* polarity reverse switch to tame hot spots on stage that can cause feedback and a ground lift switch to help eliminate hum and buzz caused by ground loops.

    Features:

    - Optimized for orchestral instruments on a live stage
    - Adjustable load for piezo and magnetic pickups
    - Variable low-cut filter to control bass resonance
    - 48V phantom powered, does not require batteries
