MPS

About the MPS

The Nagra MPS (Multiple Power Supply) is a sophisticated power supply unit engineered by Nagra to deliver clean, stable, and ultra-low noise power to multiple Nagra audio devices such as preamplifiers, CD players, and DACs. It features four isolated outputs, each capable of delivering 12 V DC at 1 A via Lemo connectors, allowing simultaneous powering of up to four components. An optional internal lithium-ion battery can be installed to power one output, typically used for analog equipment like phono stages, significantly reducing noise and improving audio fidelity. The MPS includes a large custom-designed transformer, massive filtering, and ultra-low noise regulators for each output to ensure optimal performance. The front panel has a meter to display mains voltage, output voltages, and battery charge status. It supports remote switching via Nagra remote control and includes home automation input/output connectors for system integration, enabling features such as remote power-on and maintaining optimal operating temperature before listening sessions. The DC cables are directional with secure locking Lemo connectors. The MPS is compatible with a wide range of Nagra products including BPS, VPS, PL-L, MELODY, JAZZ, CDC, CDP, CDT, and HD DAC. It operates on mains voltages of 100, 115, or 230 VAC ±10%.
