DRIVE SYSTEM

The turntable is driven by a custom made bi-phase AC synchronous motor. The speed control unit uses a dedicated DSP engine to generate two independent pure mathematical sine waves which provide total control of frequency, phase relationship and amplitude. These in turn are matched (tuned) to the motor for accuracy to obtain the best possible performance. The output driver stage is a 2 channel, class AB Bi-polar design with low distortion and relay coupled directly to the motor. The entire design is implemented using high quality surface mount technology on a gold plated FR4 PCB.

SPEED RANGE

The speed range is 331/3 and 45rpm with independent memory settings via a switched encoder.

UNPACKING

Unpack and check all items against the packing list in Section 7.
Having opened the packing box carefully lift upwards the top section high density foam module which covers the turntable/ tonearm unit. Lift out the turntable lifting from under the main chassis (bottom of turntable). The turntable should be sited on a substantial table or strong audio stand which must be capable of supporting the turntable weight.
With the turntable sited lift the left side of the turntable to gain access to the motor transit screw which secures (clamps) the motor to the main chassis. Remove the motor transit screw and position the turntable squarely and centrally onto an audio stand. Ensure that the motor base posts are securely inserted into the compliance cups.
The turntable is shipped with only a small quantity of oil in the bearing housing and this should be filled before setting up the turntable. A measured quantity of oil is provided in the syringe and needs to be injected into the bearing housing.
Remove the syringe from its packing and insert the tip into the oil filler adaptor, which will be found factory fitted next to the spindle (as illustrated).
Slowly inject the complete quantity of oil into the bearing housing maintaining downward pressure throughout the operation to prevent leakage. Remove the syringe and dispose of it responsibly
Unscrew and remove the oil filler adaptor using the box spanner found inside the tool kit. Retain the adaptor for possible future use.

SETTING UP – TURNTABLE

Levelling
With the use of a spirit/bubble level ensure that the main chassis (lower chassis) is level in the lateral and longitudinal planes. The 3 feet are height adjustable and can be used to achieve a level chassis. When adjusting the feet it is recommended to slightly lift the chassis adjacent to the foot being adjusted. This aides ease of rotation of the foot and prevents the foot rubber pad binding.
Transit Locks
For transit the suspension is locked (secured) by two screws; these are accessible through holes in the driven pulley. The transit screws should be turned anti-clockwise with the supplied 4mm hex wrench and removed. The main bearing is off-loaded by four pulley transit screws. These are captive and should be turned anti-clockwise with the 3mm ball-ended hex wrench until they stop. Ensure the wrench is fully engaged to avoid damage to the transit screw socket (see page 9, transit screws).
Drive Belt
Place the drive belt over the large driven pulley down as far as the pulley flange, ensuring that it is free from twists and stretch over the motor pulley. The pulleys will be out of alignment without the weight of the platter so rotation must not take place until the platter has been fitted.
Platter
Unpack the platter and place it carefully and squarely over the turntable spindle lowering it gently down until it rests on the driven pulley, having first ensured that both mating surfaces are clean. Rotate the platter slowly by hand to position the belt on the pulleys.
WARNING:
The unique damping material (isodamp) installed on the platter top surface has been diamond turned and scrolled for intimate contact with the record. Avoid handling the isodamp material and treat it like a vinyl record as it could be easily damaged.
Suspension
The sub-chassis suspension system is set to the operating height by way of inserting the 3mm hex wrench into the centre hole of each upper gallery cover and rotating clockwise to raise the sub-chassis. The operating height is correct when a 3.5mm clearance (gap) is achieved between the sub-chassis and column base as indicated on page 9. The 3.5mm clearance is measured by use of the height setting gauge. Anti-clockwise rotation of the 3mm hex wrench will lower the sub-chassis. After setting the suspension height hold the sub- chassis fully down and then release it. Check and re-adjust as needed, noting that new suspension bands take a little while to settle down.
A single band arranged horizontally beneath the sub-chassis centralises the sub-chassis against the opposing pull of the drive belt.
If it is desired to increase sub-chassis isolation because of unusually close proximity to the speakers the recommended suspension height clearance of 3.5mm can be reduced to 2mm. This lowers the spindle/bearing housing deeper into the dampening bath and subsequently increases the dampening action.
Power Unit & Speed Control Unit
The power unit is connected to the speed control unit and turntable by way of the connection cables (Section 16) with LEMO connectors. The cables cannot be confused as they carry a different number of pins which are purposely configured to observe both safety and miss-identification. The cables are identified as A and B.
Connection Cable A – Power Unit Output to Speed Control Unit Input
Connection Cable B – Speed Control Unit Output to Turntable Input The AC mains power cable is connected to the power unit AC input.
A push ON/OFF switch is located on the rear of the power supply unit.
IMPORTANT
The mains voltage setting is indicated on the rear panel of the power unit. Before fitting the mains power cable check carefully that this matches your mains voltage.
Phono Stage Power Unit
Connect the Nagra power unit low voltage output cable into the turntable chassis connector at the rear of the turntable.
Tonearm Set Up
Synergy is equipped with a factory fitted SME tonearm. Refer to the tonearm instruction manual for set up procedure

CARTRIDGE

The tonearm and cartridge are factory installed and set up. It is advised that post shipping transit a digital stylus pressure gauge is used to check that the stylus pressure has remained at the factory setting of 2.3 grams.
Should the cartridge need to be replaced, observe the following guideline points and refer to the tonearm manual.

Before removal and installation of the cartridge, ensure that its stylus guard is in position as a precaution against accidental damage.
The Siltech silver cartridge leads have 1mm diameter receptacles for the headshell and standard 1.25mm for the cartridge. The latter may require adjustment with pointed nose pliers or a screwdriver blade for a snug fit on non-standard terminals. Connections to the cartridge must never be made by direct soldering.
The cartridge lead colour coding is as follows:
Red – Right Channel
Green – Right Channel Ground White – Left Channel
Blue – Left Channel Ground
Replacement Siltech silver cartridge leads can be obtained direct from SME.

POWER CABLE CONNECTIONS

NOTE: Mains power must be off when connecting and disconnecting Cables A and B.

OPERATION – TURNTABLE

The Model 15 precision turntable is partly run-in before leaving the factory but will benefit and improve after a few weeks of use. Do not worry if initially the bearing is not totally silent. A slight ‘swish’ barely audible at very close range in a silent room will quickly disappear after use of the turntable. If you should wish to check the speed settings and make your own adjustments the procedure is as follows:

Mains Power: the power ON/OFF button is located on the rear of the power unit. With power ON the last used speed indicator LED light will illuminate on the speed control unit fascia.
Motor Power: pressing the power button on the speed control unit fascia will start the motor. With power OFF and pressing the rotary button on the fascia the speed settings of 331/3 and 45rpm will cycle and be indicated by the speed LED. With the motor running, pressing the power button will stop the motor.
Speed Testing: the stroboscopic disc installed on the platter is used to check speeds of 331/3 and 45rpm. Use the strobe bands appropriate for your mains AC frequency. The disc should be viewed in a fluorescent or neon light. The appropriate band will synchronise and appear stationary when the speed is correct. Whilst forward and reverse band movement will indicate fast or slow running respectively. This is best observed with the cartridge fitted and the tonearm in the raised position and placed directly over the band being viewed as a reference point.
Speed Adjustment: with the motor running press and hold the rotary button for two seconds, the speed indicator LED will begin to flash. The motor is now in speed adjust mode and the speed can now be adjusted in conjunction with the stroboscopic disc. Turning the rotary button anti-clockwise will reduce speed and clockwise will increase speed. The method provides a microfine incremental adjustment. When the speed adjustment is completed depress and release the rotary button, the speed indicator LED light will stop flashing and become constant and the speed setting will be stored in the system memory for future use.
Repeat this process for the 45rpm speed range if required.

OPERATION – PLAYING A RECORD

Place the record spindle washer on the spindle followed by the record and clamp. The clamp should be screwed down clockwise enough to deflect the record flat into firm contact with the platter. With a fingertip, tap the record in three places equally over its surface and with a little practice it will soon become evident whether or not the record is touching the platter. If not, some further tightening of the clamp may be necessary.

OPERATION – TONEARM

With the control lever in the raised position move the tonearm out of the armrest and position the tonearm so that the stylus is over the selected record groove.
To lower the stylus onto the record move the control lever forward until it is just past top dead centre. This will set the lowering control in motion, at which point it will take over the movement of the lever, giving a smooth controlled descent.
Note: For the correct descent time the control must be operated exactly as above. The speed will be increased considerably if the lever is pushed down instead of being allowed to fall of its own accord.
To raise the stylus from the record slowly move the control lever back to its original position. When the tonearm is not in use it should always be returned to the armrest for safety.

MAINTENANCE – TURNTABLE

There are no critical adjustments or need for ‘tweak’ and only very little maintenance. Clean the drive belt occasionally by drawing it through a piece of soft tissue or linen moistened with lighter fuel. The same material may be used to clean the periphery of the motor and driven pulleys.
The suspension dampening bath is automatically sealed when the sub-chassis is locked down and does not require maintenance.
Replace the drive belt after 1000 hours use. A replacement belt is available from SME.
The life of the suspension bands will depend on climatic conditions. If eventually they should stretch beyond further adjustment, replacements are available from SME.
Changing the suspension bands is simple. Unscrew and remove the upper gallery cover from the top of the suspension column and lift off the lower gallery cover. Remove the old band(s) and attach the new band(s) onto the anchor studs. Replace the covers and re-check the suspension height with the height setting gauge.
The motor retaining and centralizing bands will last indefinitely. However should they require replacing refer to the illustration on page 9.
There are no user-serviceable parts inside the speed control unit or power unit. A safety fuse is located below the mains socket, its replacement should only be undertaken by qualified service personnel.

TRANSIT PRECAUTIONS

The Model 15 can be safely transported,

SUBJECT ABSOLUTELY TO THE FOLLOWING PRECAUTIONS:
Short journeys by car: remove the platter, disengage the drive belt from the motor pulley, and replace the two packing strips beneath the motor and secure with the motor transit screw. Lock down the suspension. Screw down the four driven pulley transit screws not more than one turn, just enough to prevent the pulley rotating freely. The turntable itself is best placed on the floor of the car in front of the passenger seat. The platter and other items can be stowed elsewhere provided they are carefully protected. For all other transportation purposes the original packing case and materials must be used.
