Important safety instructions Please take a moment to read these instructions before installing your TT50, as they will enable you to get the best performance and prolong the life of the unit. We advise you follow all instructions, heed all warnings and keep the instructions for future reference. Positioning Choose the installation location carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibration and excessive dust, cold or moisture.
T T50 Before using your TT50 for the first time it is necessary to remove the transit screws and fit the drive belt, platter and lid. 2. Next fit the drive belt around the sub-platter and the smaller diameter part of the motor pulley (for 33rpm use). Please very carefully remove the parts separately from the packaging. Note: It is very important to avoid getting sweat or grease on the belt as these will deteriorate the performance and reduce the belt's lifespan.
Assembly/setup continued 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. This adjustment must be done carefully. Do not forget to remove the cartridge protection cap if fitted.

Operating instructions Cartridge replacement/adjustment Playing records IMPORTANT! The TT50 is compatible with 33 1/3rpm and 45rpm records between 7” and 12”. The TT50 record player is supplied with a factory fitted and adjusted Audio Technica AT95E Moving Magnet cartridge fully aligned and setup at the factory. The following instructions for adjusting the cartridge are provided in case the cartridge is replaced by a different model at a later date.
Cartridge alignment Because a normal tonearm pivots about its bearing point as it traverses a record, the angle between the cartridge body and record groove will gradually vary as the record is played. 4. Now turn the platter by hand and place the stylus tip at position B. Again look directly from above to see if the cartridge body sides are parallel to the lines on the protractor. The idea of cartridge alignment is to minimise this inherent error.
Cartridge replacement/adjustment continued Adjusting the azimuth Anti-skating (bias) adjustment The cartridge needle must be vertical in the record groove in order to trace the groove wall modulations correctly. Refer to the 'Assembly/setup' section of this manual. 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). 1.
