Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Compatibility: The 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, Media Source 200, and
Meridian Explorer (all sold separately). The power supply matches Meridian's
Prime Headphone Amplifier/DAC chassis for perfect stacking. The addition of the
Prime Power Supply to these components provides an enhancement in their
Highly-Regulated Power Supply: The Prime Power Supply incorporates a
special low-noise, highly regulated linear power supply to help deliver the
highest possible audio performance to your Meridian components and connected
gear. 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.
Multi-Stage Regulators: 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
utilize heavily over specified 5A linear regulators, selected by a rigorous
evaluation process, including extensive listening tests.
USB Input/Output: The Meridian Prime Power Supply is fitted with a USB
(type-B) input which connects to the USB output of your computer or PC, using a
USB-A to USB-B cable (sold separately). The power supply's USB (type-A) output
connects to the Meridian Prime Headphone Amplifier, using the included USB-A to
mini-USB cable. The USB input/output features a new high-efficiency low-dropout
(LDO) linear regulator design that features less than 5μVrms output noise in the
range of 10-100kHz.
12V Power Outputs: Up to five Meridian products, using Meridian Prime
power leads (one included) can be connected to the power supply.
6' AC Power Cord: The Meridian Power Supply includes a detachable IEC
3-prong AC power cord.
