德国佬对这个很有情趣,讨论的很热闹,该页都到了200多页了。
The PS1 is made of gray plastic—or, at least, all of the surfaces are that eyes can see or fingers can touch. That was no surprise, and no disappointment: The preponderance of audio products housed in thick, machined alloy enclosures that are heavier, fancier, more metallic, and, worst of all, much more expensive than they need to be—more expensive, often, than the parts they enclose—is one of the most depressing things about this hobby. Plastic is fine with me. Inside the PS1, a KSM-440 transport—widely available as a replacement part for under $20—is isolated from a lightweight sheet-metal frame by three compliant rubber grommets. The edges of that frame provide some measure of shielding between a rudimentary switch-mode power supply (built with some very old-style parts, leading me to assume that it was bought-in from a different manufacturer) and the remainder of the circuitry, the latter heavily dependent on surface-mount technology. The PS1 has a detachable AC cord for household current, and connects to a line-level stereo input in one of two ways: RCA output jacks of the usual sort, or a 12-conductor audio-video socket, only five conductors of which are used. The latter is for use with a supplied cable, with molded RCA plugs at the other end. The only controls on the unit itself are two buttons labeled Reset and Power, and a third for opening the transport cover, which is purely mechanical. All other controls exist only on the remote handset, which is hardwired to the main unit, à la Mattel's Robot Commando toy of the mid-1960s.
