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 con-
tains 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.

DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
ATTENTION: DANGER D’ELECTROCUTION. NE PAS OUVRIR.
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.
This product was tested and
complies with all the require-
ments for the CE Mark.

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.

Grounding 
Please check if the TEP 302 needs to be grounded: Turn the vol-
ume 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 hum-
ming 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 remem-
ber: 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.
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.
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.
Note: When the needle touches the record you may hear
some cracking noises.
When connecting the RCA cables, always make sure you
don’t mix up the channels!

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 turnta-
bles 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 ampli-
fication, 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):

Both switches On: MC
Both switches Off: MM
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, de-
pending on the pickup system you use (MM is recommended for
high-output MC systems).
Now you can conduct your fine tuning. Most manufacturers of pick-
up systems don’t give any recommendations regarding the ideal set-
tings, 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 set-
tings and values, please refer to the following chart.
Table of values (capacitance)
Switch “ON” Capacitance
none 15 pF
1 115 pF
2 235 pF
1+2 350 pF

Adjustments for MC systems
Input impedance: 1000 ohms
Input capcitance: 15 pF
The permanent input resistor cannot be deactivated. The input im-
pedance can be adjusted by using switches 3 to 6 (adjustment units
). All matching resistors are connected in parallel, therefore allow-
ing impedance values between 99 ohms (all resistors used) and 1000
ohms (no additional resistors used).
This is how you can find the best settings:
First listen to your favorite record using the highest impedance, then
the lowest, and finally select a resistor with a value of about 600 ohms.
Now try different adjustments until you get the results you want. All
values can be found in the table below.
Keep in mind to set both channels to the same value!
Table of values (impedance)
Switch “ON” Impedance Switch “ON” Impedance
none 1000 ohms
6 783 ohms 3 130 ohms
5 600 ohms 3+6 126 ohms
5+6 514 ohms 3+5 120 ohms
4 405 ohms 3+5+6 116 ohms
4+6 364 ohms 3+4 109 ohms
4+5 319 ohms 3+4+5 102 ohms
4+5+6 293 ohms 3+4+5+6 99 ohms

Operation
12
Once the TEP 302 is properly set up, the unit is fully functional
after switching it on.
Please consider that it takes around 50 hours of operation until the
TEP 302 reaches its full sonic quality.
Ambience 
Adjust the brightness of the blue illuminated Thorens logo at the front
panel by jiggering the rotary switch  (see drawing at p. 7).
Switching on/off
Push the power button on the front panel to switch the unit on and
off. While the appliance is turned on, the blue Thorens writing is il-
luminated.
Always turn on the TEP 302 first and the amplifier(s) afterwards. For
shutting down the system, repeat the steps in reverse order.
Ultimately put on a record and slowly increase the volume at the
amplifier.
When the needle touches the record you may
hear some cracking noises.

Maintenance
Cleaning
Remove dust by wiping the unit with a soft dry cloth. The chromium
front-plate can be polished with a soft purpose-designed cloth. If
necessary use a soft glass-cleaning detergent on a soft cloth. The
wooden side-cheeks can be cleaned in the same way.
Never use benzine, thinner, alcohol or other volatile agents
and avoid spraying cleaning detergents into the ventilation
slots on the cover!
No user-serviceable parts inside. Unauthorized
opening, repair or modifications of the unit will
result in loss of warranty.
TO PREVENT RISK OF ELECTRICAL SHOCK, DO
NOT OPEN THE POWER SUPPLY UNIT.
