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.
Overloading
Do not overload wall outlets or extension cord as this can result in a risk
of fire or electric shock. Overloaded AC outlets, extension cords, frayed
power cords, damaged or cracked wire insulation, and broken plugs are
dangerous. They may result in a shock or fire hazard.
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. Do not place the unit on
an unstable surface or shelf. The unit may fall, causing serious injury to
a child or adult as well as serious damage to the product. Do not place
other equipment on top of the unit. Do not install near any heat sources
such as radiators, heat registers, stoves, or other unit (including
amplifiers) that produce heat. No naked flame sources, such as lighted
candles, should be placed on the unit.
Lightning
For added protection during a thunderstorm, or when it is left
unattended and unused for long period of time, unplug the unit from the
wall outlet and disconnect the antenna or cable system. This will prevent
damage to the unit from lightning and power-line surges.
Cleaning
To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray
an aerosol at or near the unit.
Use only with cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the unit. When a cart is used,
use caution when moving the cart/unit combination to avoid
injury from tip-over. This unit must be installed on a sturdy,
level surface. Do not place in a sealed area such as a
bookcase or in a cabinet.
Attachments
Do not use attachments not recommended by your dealer as they may
cause harm to the unit. Only use the specified attachments/accessories
with this unit.
WARNING - To reduce the risk of fire or electric shock, do not expose this
unit to rain or moisture. This unit must not be used near water or
exposed to dripping or splashing water or other liquids. No objects filled
with liquid, such as vases, shall be placed on the unit. In the event,
switch off immediately, disconnect from the mains supply and contact
your dealer for advice. The unit can be used in moderate climate.
Servicing
Refer all servicing to qualified service personnel. Servicing is required
when the unit has been damaged in any way, such as power-supply cord
or plug is damaged, liquid has been spilled or objects have fallen into
the unit, the unit has been exposed to rain or moisture, does not operate
normally, or has been dropped. These units are not user serviceable,
never attempt to repair, disassemble or reconstruct the unit if there
seems to be a problem. A serious electric shock could result if this
precautionary measure is ignored. In the event of a problem or failure,
please contact your dealer.
Electronic audio components have a running in period of around a week
(if used several hours per day). This will allow the new components to
settle down, the sonic properties will improve over this time.
Grounding and polarisation
Do not defeat the safety purpose of the polarized or grounding type plug.
A polarized plug has two blades with one wider than the other. A
grounding type plug has two blades and a third grounding prong. The
wide blade or third prong are provided for your safety. If the provided
plug does not fit your outlet, consult an electrician for replacement of
the obsolete outlet.
Contact the service department should any of these conditions occur:
- When the power-supply cord or plug is damaged.
- If liquid has been spilled, or objects have fallen into the unit.
- If the unit has been exposed to rain or water.
- If the unit does not operate normally after following the operation
instructions, adjust only those controls that are covered by the
operation instructions.
Power sources
The unit should be operated only from the type of power source
indicated on the marking label. If you are not sure of the type of power-
supply to your home, consult your product dealer or local Power
Company.
- If the unit has been dropped or damaged in any way.
- When the unit exhibits a distinct negative change in performance.
Power cord protection
The unit must be installed in a manner that makes disconnection of the
power supply from the mains socket outlet (or appliance connector from
the rear of the unit) possible. Where the power supply is used as the
disconnect device, the disconnect device shall remain readily operable.
Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
unit.
Be sure to insert each power cord securely. To prevent hum and noise, do
not bundle interconnect leads with the power cord or speaker leads.

Assembly/setup
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.
Use absorbant kitchen paper to remove any oil or grease from the outer
edge of the hub and the belt if necessary.
3. Fit the main platter over the spindle of the sub platter.

6. 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
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.
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.
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.

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.

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.

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. One mark on the
scale represents 1 mN (0.1g) of downforce.

Note: The recommended downforce for the factory fitted cartridge is
20mN / 2.0g.
7. Carefully remove the protective cover from the supplied cartridge.
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.
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.
The anti-skate adjustment has been designed so that it is matched to
the tracking force adjustment (higher tracking force requires higher anti-
skate) and should be set to the same numerical value.
Before adjusting the downforce, first set the anti-skating adjustment to
zero.
Setting the correct anti-skate ensures that the average pressure on both
sides of the stylus is equal for best stereo separation and tracking
ability.

IMPORTANT!
Playing records
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.
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.
It is not necessary to adjust the factory fitted cartridge.
The supplied cartridge has a lifespan of approximately 1000-1500
hours.
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.
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.
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.
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
L
R
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.

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.
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.
The idea of cartridge alignment is to minimise this inherent error. A
simple alignment protractor is included in this manual to facilitate this.
Note: The TT50 is fully aligned at the factory for the supplied AT95E
cartridge and does not require this adjustment to be made unless a new
or different cartridge is fitted.
The supplied protractor allows the error to be adjusted out at two critical
positions on the record surface (63mm and 120mm radius) in such a
way that then minimises the error at all other positions. The protractor is
simply cut out from the manual and placed on the turntable as
described, a printable version is also available for download on the
Cambridge Audio website at: www.cambridgeaudio.com/support.php
5. If the cartridge body sides are not parallel to the lines on the
protractor, move the cartridge body back in the headshell a little (a
millimetre or so).
The procedure is as follows:
1. Move your cartridge to the front-most position possible in the
headshell as shown.
6. Lift the tone arm up and turn the platter by hand to go back to
position A, realign the cartridge body so that it is again parallel to the
lines on the protractor without moving it back or forwards in the
headshell (i.e. try to rotate the body only).
2. Using a scalpel or similar, cut the dotted line where the hole shown
on the Alignment Protractor and place it over the turntable spindle.
The Alignment Protractor is located in the ‘Technical specifications’
section of this manual.
The cartridge protractor can also be photocopied or downloaded from
our website and printed. After copying/printing always check the mm
measurement reference scale against a ruler which then makes sure
your protractor is accurate. Copiers and printers can sometimes slightly
distort the images they print, so if you find this to be the case make
adjustments to the copier or print scaling and reprint until the scale is
correct.
7. 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.
8. 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.
Cartridge downforce adjustment
Refer to the 'Assembly/setup' section of this manual.
3. Turn the platter gently by hand so that you can carefully rest the
stylus tip exactly on the cross at position A. Looking directly from
above carefully rotate the cartridge body so that its sides are parallel
to the protractor lines as shown.
Note: Lift the tone arm before turning the platter to avoid damaging the
the needle/stylus.

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.
Anti-skating (bias) adjustment
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. Slacken off the screw just enough to be able to revolve the arm tube
without applying force.
Side view
Note: Do not remove the screw completely!
2. With the aid of a good magnifying glass adjust the needle until it is
vertical in the groove (i.e. perpendicular to the record's surface).
Ideally this should correspond to the top surface of the cartridge body
being parallel to the record surface. When you are satisfied that the
needle is vertical, retighten the screw carefully.
Under no circumstances should the arm tube be adjusted with the
needle still in the record groove! Irreparable damage may be caused to
the cantilever suspension! The arm must be lifted to make each
adjustment and lowered afterwards to check it.
