Introduction
The RB303 is the latest version of Rega’s most popular tonearm.
Replacing the hugely successful RB301, the RB303 utilises a
completely redesigned arm tube. This tube design uses intelligent
re-distribution of mass to optimise performance and reduce stress
on the bearings even further. This ensures improved tracking and
maximises the amount of information a cartridge can extract from the
record surface. The hand assembled Rega RB303 tonearm is a
precision crafted product. To create the low friction levels and meet
minimum mass requirements, many parts of the arm are delicate and
require careful handling. The arm should always be treated with
respect and under no circumstances should any part be removed or
tampered with.
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 usually 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.
Fully extended 0.0 First position 1.0 Second Position 2.0
Simply push the slider in to the required anti skating setting .Your arm
is now balanced, setup and ready to use. If you have any doubts
regarding installation or setup please contact your official Rega
dealer who will be able to carry out the work for you. Thank you for
purchasing this Rega product and we wish you many hours of musical
enjoyment.
