PMA-2000 is PMA-S10 on the basis of appropriate simplified low-priced versions, there is also a model PMA-2000 with no remote control. Perhaps someone will ask, since PMA-2000 is a simplified version of PMA-S10, that PMA-S10 is what? Main line PMA-S10 is ported from TL-company Hi-End PMA-S1 body,ExPservice manual download site

Launched in 1995, get around the spoke highly of audio publications. PMA-S10 two of the most important features is the use of the UHC-MOS (ultra high current FET) amplifier, the second is suspension structure of the machine has a great deal of effort. Because of cost considerations, PMA-2000 not PMA-S10 the perfect shock absorber structureExPservice manual download site

But UHC-MOS circuit technology are inherited down. According to information on the Dragon company, PMA-2000 per channel with a pair of UHC-MOS single-ended push-pull output transistors do. Although traditional FET characteristics of excellent, but the internal resistance is higher, the maximum current is small, to get a high current output, generally require the use of a pipe parallel.ExPservice manual download site

Parallel pipe needs to be closely matched, and this pairing work is very difficult, requires extensive screening measure, spent a lot of time, which in turn led to rising costs. UHC-MOS has made some improvements from the structure, both high input impedance FET easy drive and output characteristics of vacuum tube-like properties and greatly reduces internal resistance, increase the output current. So you need a pair of UHC-MOS, they can do 80W (8 ω) output power.ExPservice manual download site
PMA-2000 shape is typical of Japanese @# the native style, color is gold for Japan @# manufacturers love. Production process there is no need to say more, whether it is the appearance of the details of the deal, or internal structure, component Assembly, have a very high standard, two day native Marantz and Onkyo @# is true.ExPservice manual download site

@# This level to produce the world's first. PMA-2000 and comments on the other machine, only low-priced imports in the amp, but the sound is senior day @# the amplifier the provoking of delicate feeling.
