4. Headshell

Headshell is stored in a separated packaging. When assembling, follow instructions:

a) Mounting the cartridge into the headshell:

6

Fitting and connecting the cartridge

Please note: Adjusting a cartridge and tonearm calls for the greatest care in order to avoid damaging the cartridge or tonearm bearings. Leave this work to your dealer if you are in any way unsure of the necessary steps and precautions to be taken.

** All cartridges with half inch mounting holes can be fitted. Leaving the needle's protection cover on, fit the cartridge to the headshell using the screws supplied with the cartridge by passing one screw through each slot in the headshell (14). Do not tighten the nuts yet.

Connect the tonearm wires to the cartridge pins as follows:

b) white left channel positive (L+) c) red right channel pos. (R+) d) green right channel return (R -) e) blue left channel return (L -)

f) The full sound quality of the record player can only be achieved if the cartridge is correctly adjusted.

Particular tools like the Pro-Ject Alignment Tool are required to accomplish this job properly.

g) If you are not well acquainted with the adjustment of cartridges you are advised to call upon the

willing help of your Pro-Ject dealer to accomplish this task for you.

For cartridge assembly use fasteners from cartridge accessories. Fix the cartridge in the middle of headshell oval holes.

h) Connecting cartridge

 White left channel L+  Red right channel R+  Green right channel R-  Blue left channel L-

i) Headshell assembly

Plug headshell into the front of the tube. Connector pin must be oriented into the groove. Fixing nut tighten on the tonearm tube properly.

j) Counterweight assembly

Put on counterweight on the support rod. Tighten the locking screw gradually and watch than the shaft entry

into thread groove. Then tighten the locking screw. Correction of counterweight’s weight is provided by

additional counterweight is also tighten by the set screw.

Setting range of counterweight:

1. Counterweight without additional counterweight

This setting balance cartridge with weight 4.5 – 8 gr.

2. Counterweight with additional counterweight with dimensions Ø15mm, length 30mm.

This setting balance cartridge with weight 8 – 15 gr.

3. Counterweight with additional counterweight with dimensions Ø15mm, length 45mm.

This setting balance cartridge with weight 15 – 23 gr. Please note that the maximum visible part of this additional counterweight is 21mm.

8

k) Assembly of removable tonearm part to the turntable

Detachable tonearm part, which we already prepared, carefully put to it’s place.

Insert output connector carefully into socket in housing. Positioning pin must be directed to cartridge counterweight. After insertion the connector into socket, lock the connector with fixing nut.

l) Tonearm output connection

Attached signal cabel plug to tonearm 5-PIN connector, which is located on the bottom side of the turntable. Keep the right positioning.

m) Anti-skating assembly

9

Assembly of anti-skating is described in the following four steps: Step 1: Mounting the thread on the hook screw

Step 2: Put the thread on the correct position in the tonearm groove

Step 3: Mounting the anti-skating sliding mechanism on the shaft

Step 4: Positioning of the sliding mechanism. Eye of the thread insert on the pin in the groove.

When the tonearm is over the first outer groove of the record, the anti-skating thread must be already tensioned, when it’s in the end, it must be still on tension.

WARNING: When the thread isn’t tensioned at the beginning, at the end already falling on the other side. Be careful, there is a danger to rip off thread by tensile force.

10

Operation and calibration

Please note: Adjusting a cartridge and tonearm calls for the greatest care in order to avoid damaging the cartridge or tonearm bearings. Leave this work to your dealer if you are in any way unsure of the necessary steps and precautions to be taken.

1. Cartridge setting  Effective length = 304.8mm (12”)

(distance between needle of the cartridge and the vertical rotation axis of the tonearm)

 Mounting distance= 291.6mm

(distance between spindle and the vertical rotation axis of the tonearm)

 Inner nullpoint: r= 62,5mm

For correct setting you can use either the protractor or Pro-Ject Align It tool.

 Tool for cartridge alignment and adjustment  Special slip-proof tool for defining the turning centre of tonearm  Adaptable to accommodate differing tonearm lengths  Suitable for other manufacturer’s tonearms

Setting the position of cartridge in the headshell: For setting the correct position of cartridge in headshell grooves we designed for you small tool from transparent plexiglass. Please note that this tool is only for headshell from Pro-Ject SIGNATURE tonearm.

Step 1: Place the tool with groove to the headshell as shown.

Step 2: Then move the cartridge to the correct position. Correct position is, if the top of the needle is in the same plane like as comparative plane of tool. This is illustrated in the following picture.

11

Setting the vertical tracking force (VTF)

Please note: It is advised to remove stylus tip from gauge or fit stylus protection whilst making adjustments to avoid damage to stylus.

Place counterweight halfway along the counterweight support rod, being sure to have the locking screw uppermost. With the power of and platter static, place the stylus pressure gauge onto the platter. To set the required VTF place the tip of the stylus on the pressure gauge. Moving the counterweight towards the cartridge will reduce VTF and away will increase VTF. In order to avoid the damage oh the cartridge be sure that all time all the cartridges movements must be done in upper tonearm lift position. Repeat the measuring procedure until you get the correct VTF.

Adjust the VTF prior to installing the anti-skating weight. For adjustment and control of vertical tracking force (VTF) is supplied in the package electronic stylus balance Pro-Ject Meaure IT II

Product information:

 Case made of aluminium  4 digit LCD-Display with backlight  Capacity 0-5g  Variance ± 0,002g  Auto calibration function  Auto off after 60 seconds  Batteries supplied (teo AAA cells)  Dimensions (W x H x D) 122 x 25 x 55mm  Weight 170g

Adjusting the vertical tracking angle (VTA) Put a record on the platter. When the needle is lowered into the record groove and the tonearm is not resting on the tonearm rest, the tube of the tonearm should be parallel to the surface of the record. If it is not, loosen both VTA adjustment screws in the tonearm base just enough to allow vertical movement of the arm pillar without force and slide the arm up or down until it is parallel. Carefully retighten VTA adjustment screws without applying excessive force which would deform the arm pillar.

12

2. Adjusting the azimuth

The cartridge needle must be vertical in the record groove in order to trace the groove wall modulations correctly. A small azimuth adjusting screw on the headshell allows incorrect azimuth to be corrected. Correct position can be checked from the front view, preferably with needle placed on a mirror which is placed on platter.

Examples of incorrect azimuth setup:

Too much left angle: Too much right angle:

The correct position is 100% perpendicular to the record.

13

3. Mounting distance adjustment

Loosen the locking nut allows the linear shifting of the tonearm. Adjust correct distance by using of the scale. The correct mounting distance 304.8 mm on the scale is valid only if the cartridge is in the correct position on the headshell. However there are exist very special and different cartridge types which makes a correct mounting distance impossible. In this case you can change the distance of the arm easily and allow you to use all available cartridge types. Additional this feature allows you to use different alignment tools. There are existing different versions of alignment tools for setting and optimization of null points. You can get with different settings small sound variations.

4. Anti-skating force adjustment

With the anti-skating slider adjust the position of the arm weight at 45 degrees.

Downforce: Anti-skating groove: Lower than 13mN 1 13 - 18 mN 2nd from bearing rings 18 - 25mN 3rd from bearing ring

5. Adjusting the turntable plane

Put the spirit level on the top of the turntable. With feet that are screw-type balance the turntable. Control the plane in several directions.

6. Connect the turntable to the power supply and amplifier

Turntable is supplied with a power supply suitable for your country’s mains supply. Check the label before connecting to ensure compliance with the mains rating in your house. Connect the low voltage plug from the power supply to the socket on the rear of the turntable before connecting the power supply to the mains.

Connect the signal cable to your phono preamplifier Red – right channel White – left channel

7. The turntable control

 Turn on the switch located in the bottom of plinth

Turntable control is performed by the touch screen. After turning the switch on, the display shows logo Pro-Ject. Touching the screen you can control the turntable functions.

15

Touching on field 33 or 45 selects the desired speed. The display shows „WAIT“ . After reaching rated speed is displayed selected value 33,3 or 45,1 . Rated speed can be correct by touching the + or –, which changes the value by 0.1 % Turn off or pause the recording, touch STOP.

Please note : The actual shown speed must not be as the speed in reality. A lot of different possible physical variations may influence it. For correct control of turntable speed is supplied Pro-Ject Strobe it

Determining the correct spinning speed of a turntable with Strobe it: Strobe it shows circularly arranged dashes that are assigned to speed and frequency. Please remember the ring that matches speed and frequency (33 1/3 rpm with 50 Hz and 45 rpm with 50 Hz are valid for Europe). Put Strobe it on the turntable platter and start the turntable. The tonearm remains in its initial position. Align a mains powered light source directly to the turntable with Strobe it rotating. The dashes of previously pinned ring should now give the impression to stand still. If they seem to move slightly forward or backward, the speed is either too high or too low.

Note: Use normal mains-operated lamps. Daylight, fluorescent lamps (energy saving lamps) as well as flashlights

and LEDs, which are operated with direct current are not suitable.

Time and date setting

16

By touching the screen on the „T“ go to time and date setting window. Touch the mark with altered number and correct value by + or -. The set values can be saved by touching the „S“. To return to control touch the „C“.
