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.
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!
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 1000-1500
hours.
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.
White - Left channel positive (L+)
Red - Right channel positive. (R+)
Green - Right channel return (R -)
Blue - Left channel return (L -)
