Congratulations on purchasing your Thorens TEP 302!

The TEP 302 amplifies signals from a turntable to meet the require
ments of the “line level” input of any power amplifier. At the same time
it performs a RIAA equalization to provide you with the highest music
quality available.

The whole product is “Made in Germany”, which guarantees highest
sonic quality combined with a long lifespan.

We understand that you would like to start listening at once, yet you
should take a few minutes and carefully read this manual first. It con­tains important information that will help you to avoid damages and
to ensure proper wiring with the rest of your system. However, if you
still have questions of any kind, please feel free to contact us.

PLEASE READ THIS PAGE BEFORE OPERATING YOUR UNIT!

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

ATTENTION: DANGER D’ELECTROCUTION. NE PAS OUVRIR.

CAUTION

To reduce risk of electric shock, do not
remove the cover (or back). No user­serviceable parts inside.

EXPLANATION OF GRAPHICAL SYMBOLS

The lightning flash with arrowhead symbol, within an equilateral
triangle, is intended to alert you to the presence of uninsulated
‘dangerous voltage’ within the product’s enclosure that may be of
sufficient magnitude to constitute an electric shock to persons.

The exclamation point within an equilateral triangle is intended to
alert you to the presence of important operating and maintanance
(servicing) instructions in the literature accompanying the appliance.

FOR YOUR SAFETY:
Units shipped to the U.S.A. and Canada are designed to operate on 115-120 V AC

only. Safety precaution with use of a polarized AC plug. However, some products may be

supplied with a non-polarized plug.
CAUTION: TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS (POLARIZED) PLUG

WITH AN EXTENSION CORD RECEPTABLE OR OTHER OUTLET UNLESS THE BLADES
CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.

WARNING

TO PREVENT FIRE OR SHOCK HAZARD,
DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.

This product was tested and
complies with all the require
ments for the CE Mark.

IMPORTANT: DISPOSAL OF WASTE EQUIPMENT BY USERS IN
PRIVATE HOUSEHOLDS IN THE EUROPEAN UNION

This symbol on the product or on its packaging indicates that this
product must not be disposed off with your other household waste.
Instead, it is your responsibility to dispose of your waste equipment
by handing it over to a designated collection point for the recycling of
waste electrical and electronic equipment. The separate collection and
recycling of your waste equipment at the time of disposal will help to
conserve natural resources and ensure that it is recycled in a manner
that protects human health and the environment. For more information
about where you can drop off your waste equipment for recycling,
please contact your local city office, your household waste disposal
service or the shop where you purchased the product.

Unpacking and installation

Unpack the TEP 302 and place it on a level surface in proximity of
the turntables. We suggest that you save the cardboard and packing
materials for later use.

Please make sure that the following items were delivered with
your TEP 302 before you proceed:

Scope of supply:

Never expose the unit to either of the following conditions:

Locations near air ducts, radiators or other sources of
heat or direct exposure to sunlight

Extremely cold locations

Locations subject to extensive dust, moisture,
mechanical vibration, shock or poor ventilation

1 x Thorens TEP 302
1 x Power supply unit
1 x Power cord
1 x RCA interconnect

Power Supply 

Connect the included power cord with the 3-pin AC socket of the
power supply unit with an AC outlet that meets the power supply
conditions (see Specifications for more information). Connect the
power supply unit with the power connector  of the TEP 302.

Please make sure that the unit is switched off before you
proceed! (To turn it off press the Power button on the front panel).

Do not pull out the power cord when the amplifier
is switched on. The unit might be damaged.

Required line voltage for the power supply unit

U.S.A. and Canada...........................................................115-120 V

Europe, Australia and Asia................................................220-240 V

Japan...................................................................................100 V

Connecting the TEP 302

Audio input 

Connect the TEP 302 input  with the output sockets of your
turntable (use the turntable’s RCA cable).

Audio output 

Use the included RCA cable to connect the TEP 302 output with
a “line level” input (e.g. CD, Aux, DVD, Tuner...) of your amplifier or
preamplifier.

Never connect the TEP 302 with the phono
input of your amplifier! High distortion and an
extremely high input level may cause damage to
your amplifier.

When connecting the RCA cables, always make sure you
don’t mix up the channels!

Grounding 

Please check if the TEP 302 needs to be grounded: Turn the vol­ume knob of your amplifier to zero (silent) and switch it off. Now turn
on the TEP 302 and afterwards your amplifier. If you hear a hum­ming noise from the speakers, turn off the amplifier and connect the
ground socket of the TEP 302 with the ground cable of your turn-
table (This step is not necessary for Thorens turntables).

If you still hear the humming noises, they are probably caused by
power cords or DVD/CD cables. Try to place the TEP 302 as far
away as possible from possible sources of interference and remem­ber: Distance is the best protection against disturbance.

If your sound system stays silent, put on a record and slowly increase
the volume on your amplifier.

Note: When the needle touches the record you may hear
some cracking noises.

Configuration for use with MM- and MC-pickup-systems

There are two different kinds of pickup systems on the market, the so
called MM (Moving Magnet) and MC (Moving Coil) systems. Having a
MM system, a magnet attached to the pickup system moves inside a
coil and a voltage proportional to the vibration amplitude is induced.
On the other hand, when you have a MC system the coil is wrapped
around the needle and the magnets are arranged around the coil. As
the coils used in MM systems have to be rather small to save weight,
a higher output voltage is needed. While MM systems usually deploy
a voltage of several mVolts, most MC systems only use 100 µV. Now
adays you often find mixed types as well, they are called high-output
MC systems and have a voltage of up to 2.5 mV.

Due to the better sampling resolution today most high quality turnta­bles make use of the MC system. However, there are still some very
sophisticated MM systems available.

The TEP 302 was designed to handle both systems without any loss
in quality. To handle the differences between them (MC: higher ampli­fication, adjusted by resistors MM: adjusted by capacitors) there are
four adjustment units on the bottom of the appliance (two for each
channel – on the left: left channel, on the right: right channel):

Configuring the TEP 302

The following steps don’t have to be repeated until you change
your pickup system.

Keep in mind to set both channels to the same value!

Begin with setting the adjustment units

 to either MC or MM, de­pending on the pickup system you use (MM is recommended for
high-output MC systems).

Both switches On: MC
Both switches Off: MM

Now you can conduct your fine tuning. Most manufacturers of pick
up systems don’t give any recommendations regarding the ideal set­tings, they suggest that you adjust the system to your personal taste
(e.g. while listening to your favorite record).

Adjustments for MM systems

Input impedance: 47 kohms
Input capcitance: 15 pF

By using switches 1 and 2 (adjustment units ) you can connect
additional matching capacitances. For an overview over possible set­tings and values, please refer to the following chart.
