The TT50 has been jointly developed between Cambridge Audio and Pro-Ject and features several parts unique to this model such as a proprietary arm with non contact magnetic anti-skate. Other features include a Cambridge Audio made acrylic platter, coated with a layer of elastomer paint for careful control of resonance and matched acoustic impedance to the vinyl record for maximum detail retrieval. The isolation type feet also control resonance and provide a measure of feedback resistance to vibration. [. . . ] Use absorbant kitchen paper to remove any oil or grease from the outer edge of the hub and the belt if necessary. Fit the main platter over the spindle of the sub platter. Accessories (included) 30 0 5 2 4 0. 5 1 0 Drive belt Hook Earthing lead Counterweight 4. Fit the lid to the turntable, carefully over the hinge prongs and adjust the screws if necessary until the lid stays open where you want it to without being too stiff to open or close. L R Rear view 5. First remove the two red transport screws which secure the motor during transportation. Connect the TT50 using a RCA/phono to RCA/phono interconnect lead to an amplifier with either an internal or external phono stage. Always use the phono input (sometimes labelled Gram, Disc or RIAA) on your amplifier. As the TT50 is supplied with a Moving Magnet type cartridge use either the input marked for MM phono on your amplifier, or switch your phono stage to MM mode. Remove 30 0 5 2 4 0. 5 1 0 The earthing wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided). These protect the motor and its assembly by preventing it from moving around in transit. The screws must be removed before use to allow the motor to float on its suspension, this provides a level of isolation of between the motor drive and external vibrations and vice versa. Retain the screws so that they can re-fitted should you need to move the turntable in the future. 5 If your amplifier does not have an input suitable for phono cartridges you will require a separate phono amplifier stage such as our Azur 540P or 640P models which are then connected between the record player and a free line level input of the amplifier. For further information contact your Cambridge Audio dealer. Assembly/setup continued Connection using phono stage 2. Carefully rotate the counterweight until the armtube balances out, i. e. The arm should return to the balanced position if it is moved up or down. Do not forget to remove the cartridge protection cap if fitted. TT50 L R Phono Stage Amplifier Connection using amplifier with built-in phono stage 3. Hold the counterweight so it cannot rotate and your setting is not lost, and gently revolve the downforce scale ring only until the zero is in line with the white line. Check whether the arm still balances out. TT50 L R Amplifier with phono stage 4. Now rotate the whole counterweight and scale ring together counter clockwise (seen from the front) to adjust the downforce according to the cartridge manufacturer's recommendations. Note: The recommended downforce for the factory fitted cartridge is 20mN / 2. 0g. 7. Carefully remove the protective cover from the supplied cartridge. Cartridge downforce adjustment The supplied counterweight is suitable for cartridges weighing between 3. 5 and 5. 5g. An alternative counterweight for cartridges weighing between 6 - 9g is available as an accessory part, contact your Cambridge Audio dealer if you need this part. Before adjusting the downforce, first set the anti-skating adjustment to zero. Anti-skating (bias) adjustment The TT50 features a magnetic anti-skate which applies a non contact force to the arm to counter-act the natural force applied by the record as the stylus is forced towards the center of the spiralling groove. [. . . ] Again lift the tone arm and turn the platter by hand then place the stylus tip back at position B. Again look directly from above to see if the cartridge body sides are now parallel to the lines on the protractor. If not, move the cartridge body back in the headshell by another millimetre or so and repeat the procedure. The idea is to find the position in the headshell front to back that allows adjustment of the cartridge so that its sides are parallel to the lines on the protractor at both positions A and B.
