Thank you for purchasing this Cambridge Audio TT50 turntable. 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.

The isolation type feet also control resonance and provide a measure of
feedback resistance to vibration. The TT50 turntable is supplied with an
Audio Technica AT95E Moving Magnet cartridge fully aligned and setup
at the factory.

The TT50 should always be mounted on a good quality level support,
preferably one designed for use with turntables.

Your turntable can only be as good as the system it is connected to.
Please do not compromise on your supports, amplification, speakers or
cabling. Naturally we particularly recommend models from the
Cambridge Audio Azur range which have been designed to the same
exacting standards as this turntable. In particular pay attention to the
quality of your phono stage. The Cambridge Audio Azur 540P or 640P
models for instance are an excellent match for the TT50. Your dealer
can also supply excellent quality Cambridge Audio interconnects to
ensure your system realises its full potential.

Thank you for taking the time to read this manual; we do recommend
you keep it for future reference.

Matthew Bramble,
Cambridge Audio Technical Director
and the Turntable design team.

Safety precautionsLimited warranty

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.

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.

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.

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.

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.

- If the unit has been dropped or damaged in any way.

- When the unit exhibits a distinct negative change in performance.

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. 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.

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.

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.

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.

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 power­supply to your home, consult your product dealer or local Power
Company.

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.
