• One information pack and warranty card.
• After removing the product and the above items please retain All packing materials. Correct packing is required for the transportation of your product.

MAINTENANCE

• After disconnecting the Caspian RPP/RPM/VSC from the main supply, the cabinet and front panel may be cleaned with a dry lint-free cloth. Avoid using abrasive substances or solvents.
• Roksan Audio Ltd declares that the apparatus “Caspian VSC / RPP / RPM” complies with the essential requirements and other relevant provisions of Directive 1999/5/EC.

AC MAINS SUPPLY

• Your Roksan Caspian product is set to operate from a fixed supply voltage which is marked on a label next to the mains input plug. Before connecting the mains lead please check that your mains supply corresponds to this label as below.
• 230V products: Voltage range 220V-240V
• 115V products: Voltage range 100V-120V
• The mains lead supplied with this product has an IEC mains socket which plugs into the IEC connector on the unit’s rear panel. The other end is normally attached to the appropriate mains plug for the country.
• The plug should not normally be removed from the lead. If you DO remove it, please dispose of it safely so it cannot be plugged into a mains socket whilst in a potentially dangerous condition. We suggest you obtain a new lead from your dealer.
• Should you move to an area that has a different mains voltage or plug from that originally supplied, please contact your Roksan dealer for assistance.
• Please observe correct mains polarity at all times.
• The main fuses are located on the rear panel next to the IEC main connector. They must only be replaced with a fuse of the type and rating as described on the fuse rating label on the rear panel.
• These products require a connection to the earth (ground).
• The earth wire (green/yellow in the UK) of the mains cable supplied with your product must be connected to a suitable established for this purpose by your electricity supply company. If you are in any doubt, consult a qualified electrician.
• If the equipment is likely to be unused for some time, unplug it from the main supply.

LOCATION

• Your Caspian analog product should be located in a well-ventilated area and kept away from sources of heat, dust humidity, and direct sunlight.
• It may be maybe positioned either as a freestanding unit or alongside another A/V product.
• Never place it on a carpet or any surface likely to hinder normal ventilation.
• Do not remove any panels or text to service it yourself.
• Unauthorized servicing will void the warranty.

ROKSAN CASPIAN VSC ( & VSC 2S)

• The vinyl system control will have one of two options fitted.

Option 1. – VSC

• RPM Reference Speed Control module
• RPP Reference Phono Preamplifier module
• 1 x DS1.5 power supply to power both of the above

Option 2. VSC 2S (recommended for optimum performance)

• RPM Reference Speed Control module
• RPP Reference Phono Preamplifier module
• 1 x DS1.5 power supply for RPM module
• 1 x DS1.5 power supply for the RPP module
• When option 2 (VSC 2S) is chosen by the customer then the relevant LED indicator (2) on the front panel will indicate that a second power supply is installed and in operation. With option 1 the light is off.
• Please note that your VSC can be upgraded to a VSC 2S after purchase.

SETUP

CONNECTING MAINS POWER

• Please refer to the front panel view.
• The molded IEC connector of the supplied mains lead should be plugged into the socket on the rear of the unit first and then plugged into the mains supply.
• The main power switch is on the rear panel of the VCS. This switch is normally left on. If the unit is likely to be unattended for a long period, switch off and unplug the main lead from the wall.

INPUT AND OUTPUT CONNECTIONS

• IMPORTANT: BEFORE ANY CONNECTIONS ARE MADE, ENSURE THE UNITS ARE SWITCHED OFF AND DISCONNECTED FROM THE MAINS.
• RPM OUTPUT LEAD: Connect the RPM output lead to the Xerxes turntable. Simply line up the four pins with the connector ‘key’, insert fully, and secure by tightening the locking nut finger tight.
• RPP: Connect the tonearm cable left and right RCA plugs to the left and right inputs and securely attach the ‘ground’ lead to the ‘ground’ terminal.
• Then connect the left and right output sockets on the phono amplifier to the left and right (line level) inputs of your pre or integrated amplifier.
• IMPORTANT NOTE: For optimum performance, it is recommended to use high-quality interconnect cables such as ROKSAN HDC-02A High Definition Analogue Cable terminate.

RPP REFERENCE PHONO AMPLIFIER MODULE

• To optimize the performance of your phono cartridge there are three gain, four input impedance, and one input capacitance selections on the RPP module.
• The relevant cartridge settings are marked and described as follows. Please make a note of this.
• IMPORTANT: The eight switches on each dip switch set the desired selection for one channel only. Both sets must be identical for correct stereo output.

SETTINGS FOR MM OR MC CARTRIDGES

• (NOTE: The example diagram shows the dip switch settings for a Shiraz MC. For other cartridges please refer to the settings below)
• If no input load is selected, the default is 47K and 47 pF.
• Both sets of dipswitches must be identical

OPERATION

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 fitted modules and the second power supply (if applicable).

USING THE CONTROLS

• 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), and 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, depending 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. Likewise, the voltage can be adjusted.
• Again this should be only necessary in very rare circumstances when operating a non-Roksan product.
• Please contact your dealer or distributor for this service.
