Connecting:
Position the PS DC so that there is space above, of at least 10-20 mm, for ventilation. By
using the control pad the PS does not need to be readily accessible.
At the rear of the PS are two female XLR outputs: 7pin XLR for motor connection and 5pin
XLR for control pad.
Connect the XLR cables to the motor input in the motor tower and at the back of the control
pad. Connect the other ends of the cables to the XLR outputs on the rear of PS DC panel.
Connect the mains cable and then switch on POWER on the front panel, which is then left
permanently on. A red LED above the START button and a green display will light up on the
front panel. There is a row of 4 round buttons. With the round button marked SPEED you
select the speed ( 33, 45, indirectly also 78 ), which is then displayed on the green screen.
The START button has LED above (red). Pressing it will start platter rotation and the LED
will turn to green. The middle two buttons are for fine speed adjustments. Above them is a
small push “store” button. Fig. 9-10.
Control pad:
This controls start/stop and speed selection. On the left side is a red/green LED and start/stop
button. On the right hand side is a button for speed selection with two green LED ( left
indicating 33rpm speed and right 45rpm). Fig.7.
Operation:
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.
