Dynavector DV 507 tonearm - Manual (Page 3)

1. Damper plate check
Gently rotate the Main Arm. If the Damper
Plate moves freely through the Damper
Magnet slit no further action is necessary. If,
however, the plates' movement is restricted by
touching or rubbing on the magnet you will
need to gently bend the plate with your finger
to avoid obstruction.
Please be careful not to over bend this
delicate part of the arm, any adjustment
should be minor and free running of the
damper plate soon obtained. Avoid knocking
or touching the plate after it has been set. Be
careful not to scratch the painted surface. (see
Fig. 3).

2. Cartridge mounting and overhang
adjustment
Correct adjustment for the overhang is needed
to obtain good performance of cartridge.
Fix the cartridge to the headshell after
adjustment for the overhang as cartridge
stylus tip is exactly over the mark on the the
aluminum template we supplied.

3. Main weight balance
As you are aware the DV507 is in fact two
arms in one. In the horizontal plane it has very
heavy inertia careful balancing with the main
weight is therefore required in order for the
main arm to rotate smoothly.
DV507 has three kinds of sub weight balancer
A, B and C due to the total weight of headshell
plus cartridge itself. The actual DV headshell
weight of 15 grams should be added to the
cartridge weight for selecting one from these
three sub weights. In this case please refer to
the next table.
In the end of the main arm there are three scale
indications due to the sub weight. For instance
when the total weight is 20 grams, choose the sub
weight A, and adjust the top end of main weight to
the line of 20 of scale A (see Fig. 5) .
