ROKSAN CASPIAN
MANUAL
SWITCHING ON
The mains power switch (No.1) is located on the underside of the VSC unit to the left. This
switch should be left on for normal operation. If unattended for a long period, the mains power
should be switched off and the leader disconnected from the main supply.
When switched on, your VCS display will illuminate the indicators of all fi tted modules and the
second power supply (if applicable).
Please refer to the front panel view.
RPM REFERENCE SPEED CONTROL MODULE
The VSC has two push buttons on the front panel. One (No.3) selects between the speeds (33
and 45), the other (No.5) switches the power of the RPM speed control on or off. When the RPM
is selected off the indicator will be indigo and when it is on, the indicator will be blue or red, de-
pending on the speed setting. For 33rpm the light will be blue and it will indicate red for 45rpm.
SPEED & VOLTAGE ADJUSTMENT
The VSC has is highly advanced speed control that regulates the current to an extremely high
level of accuracy. The factory settings are the following:
50Hz @ 33rpm
67.5 Hz @ 45rpm
This drives the platter speed at a level of extremely high accuracy. However, in the very rare
occurrence of needing to adjust the speed the ability to micro-adjust is available. This reaches
from 0% to 6.25% of the relevant speed (33 or 45 rpm) either way (slower or faster). Should you
require any adjustment this is a service procedure that needs to be completed by Roksan. Like-
wise the voltage can be adjusted. Again this should be only necessary if very rare circumstances
when operating a non-Roksan product.
Please contact your dealer or distributor for this service.
