Mounting armboard and tonearm: 
Be sure that you have an armboard with the correct pre-cut.  Mount armbase on the armboard 
and  then  mount  armboard  on  the  turntable  with four Allen keys.  Fix firmly.  The armboard 
can be fixed in both directions, so be sure you mount it correctly orientated.   If necessary a 
second cut can be made on the armboard, but this is made of aluminium. 
 
Mount the arm as instructed in the tonearm instruction manual.  Readjust the suspension due 
to the added weight, as described before, but now be more precise regarding level so that the 
lower  edge  of  the  subchassis  is  aligned  with  the  markings  on  the  suspension  towers.    Again 
retest movement of the suspension.  Route tonearm cable underneath the turntable, below  the 
armboard. 
 
  
 

Use and adjustments

 

 
Platter rotation: 
Ensure that the red LED lights up and the green display shows selected speed, when the MCU 
is switch on.  Press the start button.  It is normal to hear some crackling sounds made by the 
belt and this will disappear in a few days.  If constant noise is heard, then check the height of 
the subchassis or the position of the belt on motor pulleys. 
                                                   
   
Fine speed adjustment: 
Observe on a strobe disc if the bars are stationary.  If not (bars move in the same direction as 
platter rotation then the speed is too high) then press the plus or minus buttons few times until 
the bars are stationary (there are very small steps- so keep pressing).  On the display you will 
see a green dot in the right bottom corner indicating that change is in process.  Using a sharp 
pen, press the “store” button and the green dot will disappear.  Check speed independently for 
both speeds.  When using the strobe disc, be sure that you use it properly.  Check that you are 
looking at the correct speed and are using the correct strobe light. 
 
Factory preset speed: 
If you find out that your speed selection is out of range for some reason you should reset PS to 
factory set outputs. 
Turn the power off, wait 10 sec, press and hold the speed button and then press the power on. 
When  the  display  shows  CU,  release  the  speed  button.    The  display  will  now  show  FA  and 
then 33.  Your PS is now preset for factory preset speeds. 
                                    
                                                   
Clamp: 
The  function  of  the  clamp  is  to  press  the  record  close  to  the  platter  mat,  thus  minimizing 
vibration between record and platter and decreasing warps of the record itself. 
 
See section “suspension adjustment on page 6 regarding height of the subchassis, when adding 
extra weight like clamp.  
 
The clamp can be used without washers.  Gently screw down the clamp on top of the record.
