Raising the VTA by rotating the toothed knob, will show increased height above this
reference point in mm and lowering it will show minus numbers. The precision achieved by
this is 0.01mm. If the change in height of the tonearm comes outside this range of
measurement, the brass weight can be repositioned. The measuring device will not be
damaged by being outside its range. Each rotation of the knob corresponds to 1mm change
in VTA and it can be moved while playing records.
Use and adjustments:
Operation & speed selection
:
1. Press the power button at the front of the PS DC firmly. After 10 sec the PS is ready. The
display will show 33( or 45) and above the start button a red LED will be shown. You can
keep the PS DC switched on all the time.
2. On pressing the start button the red LED will turn green and the platter should start
rotating. To stop the platter, simply press the start button again. The red LED will show and
the platter will slowly stop rotating.
3. Press the speed button and the selected speed will change from 33 to 45. Press again and it
will return to 33.
4. Do not press and hold the start button before the mains switch is on( see Reset function).
5. 78rpm- see below
Fine speed adjustment:
Observe on a strobe disc if the bars are stationary- that is the correct speed. If they are not
(for example if the bars move in the same direction as platter rotation) then the speed is too
high. Press the plus or minus buttons a few times until the bars are stationary (there are very
small steps, press several times). On the display you will see a green dot in the right bottom
corner indicating that a change is in process. Using a pointed pen or toothpick, press the
“store” button and the green dot will disappear.
Resetting the PS causes the speed change. After the PS is reset there will be comparatively
large steps towards plus or minus speed change**. When the “store” button is pressed next
the changes will be smaller until, finally the speed changes are barely visible.
Check the speed independently for both speeds. When using the strobe disc, be sure to use it
properly. Check that you are looking at the correct speed and are using the correct strobe
light.
Temporary options:
78 rpm speed:
While platter is not rotating ( press start/stop button), then press and hold + button for 7- 10
seconds, then press speed button to show 78. Then press start for platter rotation. Pressing the
speed button will show all three speeds.
Clamp: (
Gently screw down the clamp on top of the record)
Put a washer under the LP (thin for thick records and thick for thin records) and start
screwing the clamp down. Observe the outer edge of the LP. To start with, this edge will be
above the mat but will slowly lower to touch the mat. With fingers hold the LP so that it
does not rotate. If the clamp is further screwed, the outer edge will rise.
