Unpacking and set - up
Take the record player and all accessories out of the carton.
Insert each hinge into the respective recess (Fig. 3).
Hold the dust cover parallel to the hinges (opening angle
approximately 60°), insert and push as far as it will go.
Being in this position the dust cover may be removed at
any time.

Electrical connections
By choosing the appropriate THORENS mains
transformer this record player can be operated from
nearly all existing public mains supplies. The
low-voltage plug on the cable that is coming from
the mains transformer unit is to be inserted into
jack 17 (Fig. 4) at the rear side of the record
player.
The stereo signal leads have two phono plugs which
are also known as "Cinch" or RCA-plugs. They are
marked with either the letter "L" for the left
channel or "R" for the right channel. lf these letters
are missing then most likely the right channel is
marked red, perhaps by featuring a red plug at both
ends, and the left channel is marked white or black
accordingly. The RCA-plugs are inserted into the
phono input jacks of an amplifier or receiver. The
separate single litz-wire is making a connection to
ground and is to be fastened underneath the ground
screw of the amplifier or receiver.
IMPORTANT!
ALWAYS KEEP THE SHIPPING CARTON IN A DRY PLACE FOR THE EVENT THAT THE RECORD
PLAYER HAS TO BE PACKED AGAIN FOR TRANSPORTATION.
IN THIS CASE IT IS IMPORTANT TO DETACH THE PLATTER AND PUT IT ON THE BOTTOM OF
THE SHIPPINGBOX, JUST AS IT WAS ORIGINALLY DELIVERED TO YOU.

Adjusting tone arm and pick-up cartridge
Remove stylus guard carefully. Turn the anti-skating
knob (2) counter-clockwise until it stops (Fig. 6).
Screw the tonearm counter weight (3) onto the rear
tonearm tube (Fig. 5).
Unlock the tone arm (4) a bit towards the centre of
the platter. Bring the lift-lever (5) into position
while holding back the tone arm (Fig. 6).
By turning the counter weight (3) the tone arm can
be precisely balanced in order to make it hover
freely above the platter. Move the tone arm back to
its rest.
You can now adjust the tracking force (1) and
the anti-skating force (2).
Hold tone arm counterweight and adjust tracking
force indicator until “0” is in line with the marking
on the tone arm tube.
Slowly rotate the counterweight towards the tone
arm’s bearing assembly until the required tracking
force ist set.
Adjust to 15 mN (Milli-Newton) for the factoryinstalled pick-up cartridge OMB 10.
Fig. 5
As for the required anti-skating force refer to the table
below:
Scale Tracking force (1) Anti-skating force (2)
1 = 10,0 mN 1
1,25 = 12,5 mN 1,25
1,5 = 15,0 mN 1,5
2 = 20,0 mN 2
2,5 = 25,0 mN 2,5

Mounting or exchanging a pick-up cartridge
Instead of the factory-supplied pick-up cartridge any
other cartridge with standard half-inch mounting
holes and a weight between 3 and 10 grams can be
installed.
Unscrew the cartridge and carefully remove the
coloured signal leads from the cartridge pins with a
pair of tweezers. Screw the new cartridge onto the
headshell but do not tighten. Attach the leads to the
pins while observing the correct coding.
Please note: The example shown in Fig. 8 is applicable only for the pick-up cartridge Ortofon OMB 10!
Fig. 8
Put the supplied mounting gauge onto the platter
and align the cartridge in a way that the stylus tip
is exactly above the crossover point of the auxiliary
lines and the cartridge body parallel to the auxiliary
lines. After the cartridge has been properly adjusted
tighten the screws carefully.
Adjusting the start position of the tone arm
The start position of the tone arm has been adjusted in the factory. However if there is a
deviation it may be readjusted by turning screw (9, Fig 11) to either left or right until the stylus
can be lowered exactly at the lead-in groove of the record.
Electrical Safety
Fig. 8
R = red right channel
RG = green right channel ground
L = white left channel
LG = blue left channel ground
This device is in conformity with international safety regulations (IEC 65) and
EC regulations 76/499/EWG.
ATTENTION!
During these mounting and adjustment procedures you
must be very careful not to damage the delicate stylus
and cantilever by uncontrolled and brisk movements.
Replacing the stylus
Any stylus is subject to wear even under normal playing conditions. Therefore, it is highly
recommended to have the cartridge, respectively its stylus, inspected after about 500 hours of
playing. This is because a worn or damaged stylus will eventually damage your precious vinyl
records! In order to playback vintage shellac records (78's) with optimal results the original
stylus should be exchanged with a suitable special stylus for shellacs. Please consult your
THORENS dealer for further information and details.

Selecting Speed
9
With the knob on the left the speed can be set
at 33, 45 und 78rpm (Fig. 10)
Selecting record diameter
With the button (6) on the right near the tone arm,
the diameter of the records can be pre-set, whereby
17 cm is used for "Single" and 30 cm for "Long Play
(LP)" vinyl records. This function is necessary only
when the record player is operated in its automatic
mode.
Automatic start
Remove the transparent stylus guard by carefully
pulling it towards you
The lift lever (5) must be in position UP.
Move the knob (7) into position Start and the tone
arm will be automatically lowered onto the record (Fig.
11)
Manual start and tone arm lift
Bring the lift-lever (5) into position UP.
Unlock the tone arm from its rest and move it above
the lead-in groove of the record. The motor and
platter will now start turning. By lowering the
lift-lever (5) the tone arm gently declines, thus
being very kind to your precious records. With the
help of the lift-lever the tone arm may be moved up and
down again anywhere across the record while the platter
keeps turning (Fig. 11)
Stop
After reaching the lead-out groove the tone arm will
be automatically lifted up and returned to its rest.
The motor is switched off. You can also switch off
the record player by either moving knob (7) into position
Stop, or by raising lift-lever (5) into
position UP and returning the tone arm manually
to its rest Fig. 11)
