Operating instructions
Playing records
The TT50 is compatible with 33 1/3rpm and 45rpm records between 7” and 12”.
Place the record over the spindle holding the record only by its outermost edge.
Before playing it is a good idea to clean the record using an appropriate cleaning brush designed specifically for use with records, we particularly recommend the type with soft carbon fibre bristles which also reduce static charge on the record surface.
Move the arm so that the stylus is over the start of the record and then switch the motor on. Now use the tonearm lift lever to lower the stylus onto the record.
When finished lift the stylus from the record using the tonearm lift lever before turning the motor off. Return the arm to the tonearm rest.
Always return records to their sleeves to prevent dust from being collected by the record due to static attraction.
Changing replay speed
To play records at 45rpm first remove the platter, and using the accessory tool provided, hook the belt over the larger diameter part of the motor pulley. Refit the platter. To revert to 33rpm repeat the procedure using the smaller step on the pulley.
Cartridge replacement/adjustment
IMPORTANT!
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.
It is not necessary to adjust the factory fitted cartridge.
The supplied cartridge has a lifespan of approximately
The stylus assembly is removable for servicing. To replace the stylus firmly grip the green plastic stylus assembly as shown and pull it downward, replace with part number ATN95E.
Fitting of a replacement stylus or whole new cartridge is best left to a dealer as the stylus and its cantilever are very fragile and adjustment of a new cartridge is somewhat fiddly.
Cartridge fitting
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. Do not tighten the nuts yet. The supplied counterweight is suitable for cartridges weighing between 3.5 and 7g.
An alternative counterweight for cartridges weighing between 6 - 10g is available as an accessory part, contact your Cambridge Audio dealer if you need this part.
Connect the tonearm wires to the cartridge pins as follows.
Maintenance and cleaning
Your record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber parts. It is recommended to fit the stylus cover before cleaning or maintenance is carried out to avoid damage.
If the player is not used over a long period of time the drive belt can be removed to prevent unequal stretching.
Note: Always disconnect the record player from the mains power supply as a precaution before maintenance!
