Micro Seiki DDX-1000

1970s design cutie - and drool object still today !

The DDX-1000 is the original design, with two sculpted strobe markings around the 2kg / 31cm diecast aluminium platter. The resulting moment of inertia is at 330kg / cm2 and the top mat in fact covers a thick cork sub-mat set inside the platter itself.

The DDX-1000, in real late 70s modernism is a direct-drive. The motor is a DC-Servo with FG frequency generator reference set through the strobe neon lamp which "checks" how many stripe it sees and rectifies if necessary ; the resulting speed accuracy is of 0,03%.

The starting torque is of 1,2kg / cm and load characteristics allow the DDX-1000 to remain below 0,04% deviation up to a 3g load set at the outer limit of the platter - specs-wise, we're here under the contemporary Sony TTS-8000 for instance...

The heigh-adjustable feet are typical Micro Seiki (or Luxman, of course :) and contain a mix of inert damping (neoprene stuffing) and mechanical damping (spring).
The is no Quartz Lock on the DDX-1000 ; the MD-1000 power-supply box holds the power on/off, start 33rpm, start 45rpm and stop buttons plus two ± 6% speed controls.

The AX-1G to AX-6G tonearm bases fit everything from the ubiquitous SMEs to the Technics EPA-100 or PUA-1600L.

Of course, the motor of the DDX was used as basis for the Marantz Tt 1000 (1979), and that of the DQX-1500 (an updated DQX-1000) for the Tt 1000 mkII (1992). And, as often, Micro's direct-drive motors came from... Victor.

The DDX-1000 naturally spawned a myriad of lookalikes and still does today - perhaps better than the original, perhaps not. Or not that much :)


The b/w images come from a swedish catalog dedicated to the DDX-1000 and MA-505 tonearm printed by Septon Electronic AB - courtesy of Göran Karlsson ; color ones from japanese catalogs of my own.
