Many manufacturers 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 theirs, 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 a Purple Sweet Ten 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 the Purple modules already take advantage of second output and the 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!
