Optional parts
SSBS/B(Sorane Sliding Base with Silver/Black color) is optional parts to replace SME
standard base for customer's convenience.
Direction of sliding sub-base should point to the turntable spindle, while the mounting

Mount the tonearm base to turntable plinth
/ Arm Boad
1-a Determine where the arm base should be mounted by using the supplied
arm mounting template.
1-b Put the larger hole of the template onto the center spindle. Take the
attached marking pin supplied (as illustrated below) and push it through the
small hole at the opposite end of the tonearm template (the hole opposite the
spindle hole). Keep the needle perpendicular to the template. You may now
mark the center point of the tonearm base. The center point of the tonearm
base is also the pivot point.
1-c At the same time, mark the 3 holes for the screws that mount the arm
base to the armboard.
1-d Do not drill holes yet !
1-e Having marked the center, check to see if there is sucient clearance
for the tonearm and the dust cover (if you have a dust cover). Pay
particular attention to the counterweight shaft.
1-f After you have veried the dust cover will work with the chosen arm
base location, drill one 22mm hole (this is the center, which allows access
to the tonearm stem and cable) and three 3.5mm holes (for the screws that
mount the arm base).
*22mm diameter hole: For tonearm shaft!
*3 x 3.5mm diameter holes: For tonearm base xing screws!
Attach the cartridge to headshell
Connect the wire leads to the cartridge pins, and attach the cartridge to
the headshell with screws. (See the gure below) Screws are not included
in this tonearm kit. They are usually included with the cartridge, from the
cartridge manufacturer.in mm, will give accurate results.
Headshell Azimuth Adjustment
6-a Sorane tonearms come with adjustable headshells. There is an Allen or
hex set-screw in the side of the headshell. There is a corresponding Allen/Hex
Key to allow the user to adjust the headshell.
6-b As shipped from the factory, the headshell adjustment Allen set-screw
is set to approximately 90 degrees, with the intention that customers should
adjust the headshell to match their unique setup (cartridge, plinth, platter,
etc.). Customers are requested to make nal adjustments after mounting the
cartridge, then installing the headshell on your Sorane tonearm. It is important
to make sure the stylus is perpendicular to the surface of the record. Often
it is helpful to use a mirror (if you do not have a mirror, a CD will also work).
The main thing is to understand that many stylus assemblies are not perfectly
perpendicular, and sometimes platters are concave, so that it is important to
adjust the stylus until it is perpendicular with the groove.

Mount SA-1.2 shaft through the Base hole
2-a Carefully push the tonearm shaft through the hole in the arm base and
then fasten the set-screw with the hex key supplied with the tonearm. Be
careful not to over tighten!
2-b Adjust the tonearm height to make the tonearm parallel with the
surface of the record when the stylus is touching the record. This is the
starting point, and further fine tuning may be necessary depending on
the geometry and the stylus type of the cartridge. Consult the cartridge
manufacturer for correct VTA and VTF!
2-c The cueing platform has already been set at the correct height but can
be adjusted by using the supplied hex key.
Cartridge tracking force adjustment
3-a Verify that the anti-skating knob (number 3) is set at 0 grams.
3-b Ensure that the sliding tracking force adjustment knob (number 4 ) is
set to zero (the point furthest to the back of the tonearm and closest to the
pivot point).
3-c After the cartridge is correctly adjusted for overhang, adjust the
counterweight (number 1) so that the arm is floating with the stylus
approximately 3-5mm clear of the vinyl record. Once this adjustment is
made, the counterweight should be xed by the set-screw located on the
side of the counterweight (number 2 below), using the supplied hex key.
3-d Add tracking force by using the sliding counterweight located in the
middle of tone arm (number 4 below). As the middle counterweight slides
forward, the tracking force increases. The tracking force can be increased
to a maximum of 3.0 grams with the middle sliding counterweight pushed
all the way forward to the headshell end of the tonearm (each step is
equivalent to 0.5 grams x 6 steps, making 3 grams).
3-e The auxiliary weight is 1.5 grams (see 5). If more than 3 grams of
tracking force is needed, as might be the case when playing 78 rpm
records, place the ancillary weight in the hole as illustrated in the drawing
(see 5). Only use this auxiliary weight if additional tracking force is needed!
If it is not needed, store it away in a safe place.
Note
Because the tracking force mechanism (see 4) of SA-1.2BCS is different
from a standard counterweight system, the use of a separate VTF gauge for
precise fine-tuning is recommended. The relative accuracy of the SA-1.2
tracking force mechanism is somewhat affected by the complex interaction
of the mass of the main counterweight, its position, the mass of the cartridge,
and the mass of the headshell. So, as is usual with all tonearms, you should
verify the desired tracking force with a calibrated VTF gauge.
Auxiliary counterweight stem
In case the standard counterweight is not heavy enough to
balance your cartridge/headshell combination, an additional
counterweight stem has been supplied to give additional mass,
and greater range of adjustment.
4-a Remove the counterweight and headshell, setting them

If the tracking force needed is 3 grams, set the middle sliding
counterweight at the mark for 3 grams on the weight gauge. If more
than 3 grams of tracking force is needed, use the auxiliary weight
of 1.5 grams, along with the counterweight, in order to secure your
desired tracking force. For instance, the ancillary weight of 1.5
grams, plus 2.5 grams of tracking force set by the middle sliding
counterweight, is equivalent to 4 grams total tracking weight.
Example
aside in a safe place.
4-b Inspect the threads on the auxiliary counterweight stem.
If there is any debris, please brush it with a small paint brush,
or clean toothbrush. Debris can cause the threads to become
stuck.
4-c Attach the auxiliary stem by carefully threading clockwise
into the main stem. The threads are normal “right-hand
threaded”.
4-d Tighten firmly with your fingers, but do not apply
aggressive force. Do not use a wrench, or other tool that would
apply too much force on the bearings. Do not use thread-
locking compound (removal would require excessive force).
Finger-tighten only!
4-e The auxiliary counterweight stem provides two methods of
counter-balancing heavier cartridges and headshells.
1--The weight of the auxiliary stem provides additional force.
2--The stem also provides much greater range of adjustment of
the main counterweight (the zero-set counterweight).
Anti-skating (bias) adjustment
Set the bias adjustment knob to the same number as the tracking force.
Some experimentation may be necessary based on the specific stylus
profile used by the cartridge.
