The Purple Audio Sweet Ten 500-Series Rack utilizes a special, internal switching power supply that provides tons of current to your modules and will not compromise audio quality in any way shape or form. The Sweet Ten Rack is perhaps the finest 500-Series power supply, and will power up to 10-slots of modules in your studio.

The Purple Audio Sweet Ten 500-Series Rack is a 10 Slot 500 module rack. Many manufactures, including past Purple Audio prototypes, use linear power supplies for their racks. Traditional wisdom holds that linear power supplies are ideal for audio and generate less noise and interference. In many cases, especially with poorly designed "off the shelf" switching power supplies, this is true. However, in the case of a 10 slot series 500 rack, even a well designed linear power supply generates a substantial magnetic hum field and far too much heat to allow for internal mounting. This problem is caused in part by the wide variation of line voltage across the world. External power supplies are cumbersome and inconvenient and consideration still has to be taken as to their placement in relation to other equipment. With the advancement of switching power supplies it is now possible to have a switcher that does not compromise audio performance and delivers or exceeds all specified current needs. Purple Audio has spent years perfecting just such a power supply. They have comparatively tested all of their, and many of their competitors, modules at full bandwidth (10Hz - 500kHz) on lab quality over built bench supplies to make sure that the Sweet Ten is not compromising audio performance in any way. Simply put, your 500 series modules will perform at their highest level in this rack. Audio performance improvements are considerable.

The Sweet Ten top, side, and back panels are finished in trivalent yellow chromate cold rolled steel instead of painted steel for improved grounding and shielding. Purple Audio's ground plane motherboards provide additional grounding. Additionally, the rack motherboard has .1uf high frequency bypass capacitors at each slot to improve filtering, especially for modules with DC/DC converters. Functionally, the Sweet Ten offers 2 inputs and 2 outputs per slot. Many of Purple Audio's modules already take advantage of second output and their Moiyn mixer module will use the second input to allow for stereo balanced source injection. Future uses of these connectors include fader loops on future modules as well as a few surprises!

    Sweet Indeed! Superb 500 Chassis!
    Gerry Diwa

    Purple Audio's Sweet Ten is one of the best 10-slot chassis for me, and I have 3 of them, too! Solid consistent current supplied to the modules and smart/advanced input output options at the back.

    For a power supply, this thing is sweet!
    Cory Plaugh

    Has features that I was looking for and 2 db quiter noise floor in action than my other power supply. Only thing that would improve the feature set is channel chaining/linking. You just have to use a short patch cable to daisy chain, but with what I needed it for, I only needed to do that once. It feels and looks solidly constructed!

    Sweeeeet X 10
    Nathan Tannenbaum

    I have been using this for about 2 years now and it totally rocks! I have tried about 20 different 500 series modules and they all worked flawlessly. Having ten bays is really nice. Plus I like the big handles on the front for when I installed it.

    Paul Bento

    There is NOTHING like the Purple Audio Sweet Ten 500-Series Rack. After using and spending good $ on other racks for 500 series, I have found this one to be the best. From its quiet almost not there feel to its tight integrated power supply, You cant go any better!

    Little Tank!
    Madgan Sound

    Having owned API and BAE 500 series racks over the years I was quite interested to check out Purple's offering. The rack was very well thought out when designed, assembled with super tough/high quality materials and includes tons of features no other rack provides. This may be the best one currently on the market IMO.
