Meridian Prime Power Supply
Meridian’s Prime Power Supply is a reference-quality, high-current design based on the new linear power supplies developed for Meridian’s 800 Reference Series and specifically built for audio applications.
Meridian Prime Power Supply can be used to power a range of Meridian products, including the Meridian Prime Headphone Amplifier, Audio Core 200, Meridian Director and Media Source 200. The addition of Prime Power Supply to these components provides an enhancement in their performance, much like supercharging your car’s engine.
At the heart of the Prime Power Supply is a hand-assembled true toroidal transformer: a high-mass, low-profile, low magnetic field design. In addition to its integral magnetic shield, it’s mounted on a metal plate to shield electronics from noise.
Each output on the Prime Power Supply includes multi-stage regulation using a total of six extremely low noise linear regulators. Both the 12V and 5V USB outputs include pre-regulators prior to the output regulators. Even though the 12V outputs are rated at just 500mA, they utilise heavily over specified 5A linear regulators, selected by a rigorous evaluation process, including extensive listening tests.
Meanwhile, the USB supply features a new high-efficiency low-dropout (LDO) linear regulator design that features less than 5μVrms output noise in the range 10 – 100k Hz.
