Read this manual carefully to get the best performance from this unit.23PRECAUTIONS FOR USE Precautions for use Do not place anything on the dust cover. Objects on the cover might cause noise due to vibrations or fall o, especially during playing. Do not place the unit on an amplifier or any other device that generates heat. Doing so could cause discolora- tion, deformation or malfunction. Also avoid locations that are subject to vibrations or exposed to excessive dust, cold or moisture. As the unit could become warm during operation, always leave sucient space around it for ventilation. When installing this unit, leave a little space between it and other devices and walls to allow good heat dissipation. Do not move the unit during playing, the record rotates. Do not lift or move the unit during playing. Doing so may damage the record, the stylus, the cartridge or the unit. Always remove the record before relocating or moving this unit. Moving the unit with a record on the platter could damage the record, the stylus and the cartridge or could cause a malfunction. The voltage supplied to the unit should match the voltage as printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician. Maintenance Wipe o any dirt on the cabinet and dust cover surfaces using a soft cloth that has been slightly dampened with a diluted neutral cleanser.24 TOP VIEW TOP VIEW

INSTALLING THE DUST COVER

01. Unpack the two hinges and the dust

cover. Please take care not to scratch the bonnet.

02. Note that the hinges have a clip side and

03. Press the two clips into the designated

places on the back of the dust cover until they click into place.

04. Now push the dust cover with the hinges

into the slots provided on the back of the

INSTALLATION AND ADJUSTMENT

After unpacking, the unit is ready to play in just a few steps.

1. Place the turntable on a stable surface so that it is not slippery and stands straight.

2. Carefully place the platter on the axle. The platter is driven directly, so no further step is necessary to install

the platter. Now turn the platter a few times by hand and make sure that it runs smoothly and without noise.

3. Place the supplied rubber mat on the plate with the grooved side on top.

4. Place the pre-installed headshell in the front of the tonearm and fix it in place by turning the cap nut. The

small guide pin points straight up.

5. Screw the counterweight onto the end of the tonearm.

6. Slide the anti-skating adjustment weight in the arm base to the zero position.

7. Fold the lift lever forward so that the lift bench is lowered.

8. Remove the needle guard on the pick-up and loosen the pick-up arm lock.

9. Carefully move the tone arm towards the turntable with the finger lever so that it can swing freely up and

down. Make sure that the needle does not touch the platter or the chassis.

10. Turn the counterweight until the tone arm floats freely and swings back into a straight line by itself. If the

arm is up, turn the counterweight slightly counterclockwise, if it is down, turn it in the opposite direction until it is balanced.

11. Put the tone arm back on the support and fix it.

12. On the counterweight there is a ring with a scale for the tracking force in Pond, which can be moved inde-

pendently of the weight. Now turn this ring alone, without turning the whole weight, until the „0“ at the top is opposite the mark on the bearing block of the tone arm.28 FIRST STEPS

13. To set the desired tracking force, now turn the counterweight as a whole until the corresponding number is

opposite the mark. The supplied Ortofon 2M Blue cartridge requires between 1.6 and 2 pounds of tracking force. It is recommended to orientate yourself towards the upper end of these values.

14. Then move the weight for the anti-skating in the slot between the tonearm base at the back and the arm

support at the front to the same value. On the scale, the long lines indicate an increase of 0.5 when viewed from behind. To adjust the value, it is best to use a small screwdriver or the pin supplied for tone arm height adjustment. Important: the basic position at the base of the arm specifies the value 0.5, i.e. the other values are based on this. This completes all adjustments to the to- nearm. The description of the steps for adjusting the height of the tone arm (VTA) and for adjusting the azimuth can be found later in this document under EXPERT SET-

POWER SUPPLY Connect the external power supply to the socket on the back of the unit and then to a power outlet. Switch the main switch next to the socket on the back to the „on“ position.

CONNECTING TO THE AMPLIFIER

There are two RCA sockets on the rear panel for connecting the TD403 to an amplifier. Connect these sockets to the phono input of the amplifier using the cable supplied. The coding red means right channel and white or black means left channel. IMPORTANT: the Ortofon 2M Blue cartridge preinstalled at the factory requires a phono MM input. A high level input (designation CD, AUX, TUNER or similar) is not suitable for record playback with the TD403. RECORD REPRODUCTION

01. Place a record on the platter and select the appropriate playback speed (33.3 or 45 rpm) at the front of

the lever on the left. For small 45 singles you need the single puck supplied.

02. Unlock the tone arm and make sure the lift is up.

03. Start the platter with the lever on the front right.

04. Move the tone arm over the record with your hand so that the needle hovers over the desired spot and

lower it with the lift.

05. Playback begins.

06. When playback is finished, raise the arm with the lift and move it back to the support. Stop switches o

the motor. If necessary, put on the needle guard of the pick-up system.

07. When not in use for a longer period of time, switch o the power supply at the back with the switch.30 MAINTENANCE

The following refers to the supplied Ortofon 2M Blue cartridge and the other models from the 2M series.

• Put on the needle guard, loosen the headshell cap nut and pull it o the tonearm tube.

• Remove the needle guard again and pull the needle carrier o towards the front.

• Slide the new needle carrier onto the system body.

• Put on the needle guard again and fix the headshell to the tonearm again.

• It is not necessary to change the settings on the tone arm if it is a replacement needle of the same type. The needle should be checked after approx. 500 hours of operation and replaced if necessary. If you are unsure about this, leave the replacement of the pick-up to your dealer or another competent person. IMPORTANT RECOMMENDATION Clean your valuable records regularly with a commercially available antistatic brush or use a record washing machine. Make sure that the diamond is clean. To do this, it is best to use the small brush supplied, which you can carefully brush over the diamond from the back to the front.

TRANSPORTING THE TURNTABLE

It is best to use the original packaging of the unit for transport. Put on the needle guard and lock the tone arm in its support. For longer transport or for shipping, loosen headshell and pull it o. Then remove the rear counterweight and set the anti-skating value to zero. Then re- move the turntable and stow it on the bottom of the box. Lift the dust cover o its hinges and pack it securely.31EXPERT SETTINGS EXPERT SETTINGS

REPLACING THE CARTRIDGE

To replace the complete cartridge with another model, please follow the steps below.

• Put on the needle guard, unscrew the headshell and pull it o the tone arm tube.

• pull o the four coloured cables from the pins on the cartridge and unscrew it.

• Screw the new pick-up into the headshell and connect the cables. Do not tighten the screws yet.

• Move the pick-up in the headshell until the overhang and zero crossings fit. You will need an adjustment template for this.

• Tighten the screws. Wiring diagram of the coloured cables: Red = signal right Green = ground right White = signal left Blue = ground left If you replace the complete catridge, the tone arm must be readjusted as described above.32

CARTRIDGES WITH DIFFERENT INHER-

ENT WEIGHTS The counterweight of the TP150 tonearm is made of two parts in order to balance cartridg- es with dierent weights. The two parts are connected with two screws that can be easily loosened. However, it is advisable to adjust the weight so that it is as close as possible to the bearing of the tone arm in order to minimise the leverage eect on the arm. Therefore, always check first whether the arm can be balanced with the two weights connected. If this is not possible, unscrew the rear part of the weight. If both weights are in combination, pickups up to approx. 30 g own weight can be balanced.

ADJUSTMENT OF THE AZIMUTH

The azimuth is the correct vertical angle of the diamond needle into the grooves of the record, i.e. seen from the front, the diamond must be exactly perpendicular to the record. The easiest way to check this is to use a mirror onto which the pick-up head is lowered. The pick-up system and the image must form a line without any kinks. Alternatively, it is advisable to use a transparent stencil with a line grid, through which a slanted position of headshell and pick-up becomes directly visible. You may also be able to use a commercially available set square for this purpose. To correct a possible deviation from the correct position, the tone arm can be turned. To do this, loosen the cover of the arm base with a small flat-blade screwdriver and then slightly loosen the cross-head screw (1) located centrally underneath.

EXPERT SETTINGS33EXPERT SETTINGS

CAUTION: please only loosen slightly, never unscrew! After loosening the screw, the arm tube can be turned a few degrees in both directions. When doing so, always check the current position with a mirror or template. Make sure never to move the arm lengthwise, but only sideways.34

ADJUSTMENT OF THE TONE ARM HEIGHT

Replacing a pick-up may require a correction of the arm height. As a rule of thumb, when playing a record from the side, the arm should be parallel to the surface of the record. If this is not the case, because the new cartridge is either higher or lower, the arm height must be adjusted accordingly. A normal Phillips screwdriver (Ph2) and the metal pin supplied are needed for this. For checking purposes, a triangle or a transparent template with parallel lines printed on it are suitable. First, carefully loosen the screw (1) a little. Then use the pin (2) to turn the ring in the necessary direction until the tone arm has reached the desired height. Then tighten the screw (1) again. In some cases, the lift may also need to be adjusted afterwards because the arm sits on the lift bench even when it is lowered or cannot be raised far enough. After loosening the screw (3), the lift height can be adjust- ed.
