We hope that you will enjoy many years of listening pleasure from it. 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. [. . . ] 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. Connect the supplied power supply unit. L R 1. 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. Line inputs (such as CD, Tuner, Tape or Video) are not suitable. 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. Note: A Philips screwdriver is required. 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. floats horizontally parallel to the surface of the turntable. 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. Once the arm is correctly balanced return it to the rest. 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. [. . . ] Refer to the 'Assembly/setup' section of this manual. Note: Lift the tone arm before turning the platter to avoid damaging the the needle/stylus. 9 Cartridge replacement/adjustment continued Adjusting the azimuth The cartridge needle must be vertical in the record groove in order to trace the groove wall modulations correctly. A small screw at the bearing end of the arm allows incorrect azimuth to be corrected if your needle is not mounted exactly perpendicular to the cartridge body (which can be the case). Slacken off the screw just enough to be able to revolve the arm tube without applying force. Anti-skating (bias) adjustment Refer to the 'Assembly/setup' section of this manual. Side view Note: Do not remove the screw completely! [. . . ]
