IF YOUR PHONO SECTION INVERTS PHASE, THE HOT
BECOMES THE GROUND COLOR
The arm tube should be on its side on the foam pad when doing this.
Using tweezers or fine tipped pliers, grip the center of the red wire's connector (do
not grip the wire) and push it onto the cartridge's right hot terminal pin. In the
same way, connect each of the remaining connectors to its respective cartridge
terminal. Do not push the connectors all the way on, as this could damage the
cartridge. Always back up the cartridge with your finger when pushing on the clips.
At the rear of the arm base assembly is the connector block. Plug the Lemo
connector into its receptacle on top of the block. Notice that the connector can plug
in only one way. Align the red dots on the arms plug with the red dot on the
receptacle. Push gently and do not force the plug.
B. THE COUNTERWEIGHT:
The JMW 12.6 tone arm comes with one large counterweight installed on the rear
shaft of the tonearm. For most cartridges you will only need this large weight. The
counterweight is held in position by a setscrew.
The counterweight is used for setting the azimuth (lateral balance) of the cartridge
and the vertical tracking force.
For now, position the large counterweight to give a minimum of tracking force, just
enough force to keep the cartridge on the alignment jig.
In some rare cases it may be necessary to use two counterweights together.
Contact your dealer if a second counterweight is needed.
C. OVERHANG ADJUSTMENT & ALIGNMENT
This adjustment will yield the lowest overall distortion when playing a typical 12"
record. Do not go crazy over this adjustment. You do not know if the stylus is
aligned properly on the cantilever. You are also facing a constantly moving target
when playing a record. The arm is moving in 3-dimensions and will only
approximate the accuracy you have built into your alignment.
With the arm wand removed place the Alignment Jig into position by sliding the “V”
cutout against the male bearing and the hole over the spindle. If loose, adjust
using the two screws.
