LPS9  Ultra Low Noise Power Supply for Hi-End Audio

 

The LPS9 low noise  power supply is a universal low power extra clean power supply designed to operate the entire line of our MUSES® enabled audio boards and corresponding MCU controllers. Can power a complete Hi-End preamp. Provides ultra clean isolated analog +/- 14V rails and a filtered +5V for digital circuits. 

 

The LPS9 board features dual stage voltage regulation and a sophisticated filtering system to provide clean analog voltage rails.  The top quality components and a conservative design provide long life trouble free operation.  The circuit uses no electrolytic capacitors.

​

The isolated analog power rails provide extremely low noise power free from power line harmonics and switching circuitry artifacts.  That ensures a very low noise floor (audio "black level") unachievable by other power supply topologies.

​

The LPS9 board features a "Power On" indicator, an undervoltage, overheating, and short circuit protection.

 

The board features three input connectors, including a popular USB-C for the +5Vdc primary power source.
