it from the audio section and other sections of the player. The damper bridge is machined from solid aluminum, increasing mass and rigidity, thus helping to eliminate flexure from day-to-day operation and promoting sta- bility in the physical mechanism. All of these design attributes work in concert to provide smooth, quiet, and consistent transport oper- ation.
The Power Supply
The power supply is the foundation upon which the audio and video signals are built. The analog audio outputs utilize a dedicated power system. This consists of a custom designed low-noise, toroidal transformer, a secondary analog power section which per- forms the first stage of regulation and filter- ing, followed by a final stage of local regula- tion in the output section itself.
Power to the digital audio and video sections is provided by a switch-mode power supply that delivers a single constant voltage. This is distributed to local modules where it is con- verted to the voltages required for each indi- vidual circuit. This “point of load” power dis- tribution technique prevents unwanted inter- actions caused by uneven supply during peri- ods of high demand from any single circuit. Another advantage is the efficient distribu- tion of power reducing thermal dissipation and providing a more stable operating envi- ronment.
The Video Processor
The Nº51 provides the video performance and flexibility that one would expect from a Mark Levinson Media Player. Custom cali- brated scaling and de-interlacing are provided with support for resolutions up to 720p and 1080i. Other features include aspect ratio
