The Purple Audio Sweet Ten is an advanced 500 Series rack that stands out for its innovative use of a switching power supply, challenging the traditional notion that linear power supplies are ideal for audio applications. This rack addresses challenges associated with heat generation and magnetic hum fields in linear power supplies, especially in larger configurations like a 10-slot series 500 rack.

Key Features

• Switching Power Supply Advancements: The Sweet Ten utilizes a switching power supply, a departure from the traditional linear power supplies commonly used in audio racks. This switcher is designed to deliver or exceed specified current needs without compromising audio performance.
• Global Voltage Considerations: The variation in line voltage across different regions worldwide can pose challenges for traditional linear power supplies. The Sweet Ten's switching power supply addresses this issue, providing a consistent and efficient power solution for 500 Series modules.
• Extensive Testing: Purple Audio conducted comprehensive testing on the Sweet Ten and various competitor modules. The testing involved full bandwidth assessments (10Hz – 500kHz) on lab-quality, overbuilt bench supplies. The goal was to ensure that the Sweet Ten does not compromise audio performance and allows 500 Series modules to perform at their highest level.
• Improved Audio Performance: The Sweet Ten's design, including the switching power supply, contributes to considerable audio performance improvements. The rack ensures that connected modules deliver optimal sonic characteristics without introducing unwanted noise or interference.
• Trivalent Yellow Chromate Finish: The top, side, and back panels of the Sweet Ten are finished in trivalent yellow chromate cold-rolled steel. This choice enhances grounding and shielding, addressing potential issues associated with painted steel.
• Ground Plane Motherboards: The rack incorporates ground plane motherboards to provide additional grounding, contributing to improved overall performance and reduced noise.
• Frequency Bypass Capacitors: The rack motherboard features frequency bypass capacitors at each slot, enhancing filtering capabilities, especially for modules equipped with DC/DC converters.
• Versatile I/O Configurations: Each slot in the Sweet Ten offers 2 inputs and 2 outputs. This flexibility allows for various module configurations, and future modules can leverage the additional I/O options for expanded functionality.
• Future-Ready Design: The Sweet Ten is designed with future expansion and module developments in mind. Additional functionalities, such as stereo balanced source injection and fader loops on future modules, are anticipated.
