User manual DENON PMA-360

[. . . ] UHC-MOS technology uses a minimum number of amplifier elements while achieving approximately 10 times the normal supply of current, balancing artistic expression with high output power. The PMA-360 thus masterfully reproduces the full sonic range from soft delicate details to powerful transparent climaxes of a musical performance. [. . . ] These and other measures to minimize the effects of both internal and external vibration, such as in the mounting and placement of the various parts, contribute to impeccable sound transparency and improved localization. Chassis construction with 6 independent blocks The PMA-360 features a twin monaural axisymmetric construction with separate power amp blocks for the left and right channels to prevent mutual interference between the circuits, shut out noise, and obtain a clear stereo image. Circuits with different signal levels have been isolated into six separate blocks. And 1. 6mm thick blackcoated steel plates have been used for chassis to eliminate sound coloration caused by mutual interference between the blocks and ensure the playback of sound with a clear sense of space. Precision Direct Mechanical Ground Construction, to thoroughly suppress vibration The vibration-resistant construction was reviewed to ensure that the adverse influences of vibration on sound quality are thoroughly suppressed. The power transformer, a major source of vibration, has been "float" mounted using a variety of vibration-resistant materials. The radiator has been dampened with a vibration resistant material and a radiator stabilizer, and by mounting the radiator near the foot, interference with the power transformer and other sources of vibration is minimized. This design results in a clean, transparent sound, since the signal is amplified under ideal conditions. Independent preamp and output stage power supplies, plus powerful high current dynamic power circuit The preamp power circuit that requires stable voltage and the output stage power circuit that requires a large current supply have been placed independently from the stage of the power transformer coils. This configuration of the power circuitry that eliminates adverse influences caused by the operating current of the output stage significantly enhances the resolution of the preamp stage handling low-level signals. On the other hand, large-current Schottky barrier diodes have been used for the rectifier elements to support the expressiveness of the UHC-MOS with their low-noise characteristics and high-speed operation. And a large-capacity, block-type electrode capacitor for audio applications has been used for the power capacitor. This power circuitry supplies clean, stable power to realise a sound space that eminently balances delicate musical nuances and high power. Twin transformers with leakage cancelling mount Two transformers have been connected in parallel to dramatically improve electrical and magnetic characteristics.

Twin transformers with leakage cancelling mount Two transformers have been connected in parallel to dramatically improve electrical and magnetic characteristics. The Leakage Cancelling (LC) mount-in system, a method of cancelling mutual magnetic influences, has been used to minimise the leaking of magnetic flux, a source of noise inside the amp. [. . . ]
