Rega RB2000 User Manual

The RB2000 tonearm is packed with new features pushing the
boundaries of tonearm design. As with all Rega tonearms, each one is
meticulously hand built by a team of highly skilled technicians. The
RB2000 uses improved bearings with each one being hand selected to
be an interference fit with the paired spindle matching both the inside
and outside diameters. This is a Rega developed method of increasing
the amount of detail retrieved from the record surface, designed
specifically to maximise performance of the tonearm and cartridge.
The entire tonearm structure is designed to have the minimum of
mechanical joints whilst using the stiffest materials in all critical
areas. The tolerance of the RB2000 tonearm is so tight that no
adhesive is used at any point throughout the construction. A brand
new low mass, precision engineered, vertical bearing assembly has
been manufactured to further compliment the inherent design
philosophy of the RP10 turntable. The RB2000 uses the latest award
winning Rega arm tube. Each one which is meticulously hand polished
(keeping mass to an absolute minimum) and has been completely
redesigned to redistribute mass and further reduce stresses and
resonances. This advanced design tube increases the stiffness and
rigidity of the overall assembly whilst reducing stress on the bearings
even further.

Arm balancing and setup

With the cartridge correctly mounted and with the stylus guard
removed, ensure that the tracking force dial and Bias adjustment are

set to zero. Adjust the balance weight until the arm is “floating” with

the stylus approximately 1mm clear of the record. Note: It is normal
for the arm to swing back towards the arm clip position even with the
bias set at zero. Therefore it is advisable to gently hold the arm
bearing carrier (just below the tracking dial) thus preventing
horizontal movement during the balancing procedure.

Applying tracking pressure

Once the arm is balanced rotate the tracking force adjustment dial to

the required tracking force. Numbers ‘0’ to ‘3’ are marked on the dial.

If in doubt it is advisable to use a tracking force that corresponds

with the upper limits of the cartridge manufacturer’s range.

Applying Anti - Skating (bias) adjustment

Set the bias adjustment slider to the same figure as the cartridge
tracking force pressure quoted by your cartridge manufacturer.
Note: This is not critical and a figure between 1.0 & 1.5 will normally be
suitable for moving magnet cartridges and 1.5 & 2.0 for most moving
coil cartridges.

is now balanced, setup and ready to use. If you have any doubts
regarding installation or setup please contact your official Rega

Fitting your Tonearm

The RB2000 will directly replace any other Rega tonearm that
currently uses the 3 point mounting without any modification. If fitting
to another manufacturers product or an older Rega turntable (with
the single point nut fixing) the supplied template should be used as a
guide to ensure correct position and alignment. With so many variants
in turntable models it is important to contact your turntable
manufacturer if in any doubt before making any holes in plinths or arm
boards. Before attempting to fit the RB2000 arm to the turntable it is
important to ensure that there is sufficient clearance beneath the
turntable and that the arm does not hit the lid, top or sides. Having
checked that there is sufficient clearance in all directions (including
the maximum potential arm movement horizontal and vertical). The
next step is to find the position of the centre of the arm mounting hole.
The easiest way to do this will probably be to use the arm mounting
template supplied.

Arm mounting template guide

The supplied template is for mounting Rega three point fixing arms to
other manufacturers turntables. N.B protractor for cartridge
alignment is also printed on the same template.

1. The template should be kept flat and not bent. The distance between
the centre of the spindle and the centre of the arm hole is critical and
must be 222mm. This template will help you check your positioning
before you attempt fitting and drilling.

3. Position the other end of the template so that the clearance arc is
within the rear and side edges of the turntable base (and the lid when
closed). Also check that there is at least 250mm clearance from the
centre of the hole to the inside front of the turntable.

4. Use a long pointed probe such as a needle and push it through the

‘arm hole centre’ on the template. Keep the needle perpendicular to

the template and mark the position of centre on the turntable.

5. Having marked the centre, check again that if the arm is placed in
this position it will clear the under side of the turntable and the lid.
Also, check that the arm is in a satisfactory position to ensure easy
operation and that the position is pleasing aesthetically. When you are
certain that the arm hole centre is in its correct position (exactly
222mm from the record centre) you can drill the required arm hole.

6. The arm mounting pillar requires a diameter of 25mm which will
provide adequate clearance for accurate fitting. You can then drill the
three screw mounting holes as illustrated on the template. Make sure
the arm is straight and the holes are correctly aligned before drilling.

7. With the holes drilled, you are now ready to fit the arm to the

turntable. Ensure that you also follow the turntable manufacturer’s

instructions regarding arm fitting. Each individual turntable
manufacturer may have different requirements regarding positioning
of the arm signal lead.
