Introduction
Please take time to read this Instruction Manual before unpacking your Nexus tonearm.
This product is meticulously engineered and damage is unlikely with careful handling.
Whilst it is likely that the retailer will install this tonearm, this instruction manual has presumed the customer buying this
product has some degree of understanding about tonearms, however if in any doubt, you should contact your retailer.
Warnings
1. Do not expose the tonearm to liquids or moisture.
2. Do not adjust any screw that is highlighted as ‘DO NOT TOUCH’ on the Parts Identification page (5).
3. The tonearm bearings are precision adjusted and should not be tampered with under any circumstances.
4. When transporting the tonearm the counter weight should be removed.
5The internal wiring should not be tampered with and the 5 pin DIN connector not removed.
Packaging
The packaging is expensive to replace, so save all the packing in a dry place away from fire hazard.
The Nexus tonearm is a precision instrument and the packaging has been especially designed so that all component
parts are safe during transportation. If you should need to return your unit for service or repair, you will be required to
use the original packaging to keep it safe from damage. In the event of the packing being lost or damaged further
packing can be provided at cost.

Tonearm fitting Options
AVID TURNTABLE FITTING SME STYLE FITTING UNIVERSAL FITTING
Three types of fitting option are available, complete with the bolts required to install the tonearm.
The tonearm is supplied with the AVID fitting, the other two can be purchased separately.
Fitting Tonearm to Mounting
Before installing the tonearm, screw the VTA wheel onto the
threaded stem about half way. Then insert the tonearm into the
mounting, aligning the locking screw with one of the key ways so
the arm is positioned forward when in the armrest. Use the 2mm
A/F Allen Wrench to lock the arm in position. You do not need
excessive force to lock the arm in position.

Cartridge Installation and Set Up
Twist counter weight onto tonearm
making sure not to dislodge the
rubber O-Rings.
At this stage, push on so that the
tonearm is not applying any down
force to the cartridge.
Attach cartridge to matching colour
coded wires, being careful not to
touch stylus, keeping the guard on.
The coding is:
Red - Right channel signal
Green- Right channel ground
White- Left channel signal
Blue- Left channel ground
Review cartridge instrucons supplied
Fasten the cartridge to the head
shell using the provided screws.
For AVID cartridges, position the
cartridge approximately 0.2-0.4mm
(0.007”-0.15”) from the front face of
the headshell. Double check this
position later with the alignment
gauge provided with tonearm.

Using suitable scales, adjust the
counter weight to achieve correct
tracking force as recommended by
the cartridge manufacturer.
Scales are not supplied as most
audiophiles at this level will have
their own personal choice of scale.
Your retailer will be able to assist.
Commonly called ‘Vertical Tracking Angle’
or VTA, adjust the level of the tonearm so
that the arm tube is parallel to record
surface when stylus is sitting on the record.
For excellent sound, the VTA of the tonearm
is a critical adjustment for good sound.
We would encourage turntable owners to
adjust the angle until the vinyl sounds right.
A poorly aligned cartridge
will cause the sound to
distort and potentially
damage your records.
Called 'Overhang' is set
using the alignment gauge
supplied to position the
cartridge in the headshell
for best vinyl playback.

Bias Adjustment
Natural forces pull the tonearm, ever increasingly
towards the centre of the record, which left
uncorrected can result in mistracking, distorted
sound and record damage. Bias compensation, also
known as Anti-skate, is the mechanism that
counteracts this, and our design, gradually increases
the level of force as the tonearm gets closer to the
centre, applying increasing compensation as the
cartridge spans the record. The amount of bias
required depends on various factors such as the
shape of the stylus tip and even the record material
itself, there is no definitive amount or setting.
To start, we suggest you rotate the bias screw to the
end stop and then unwind six full turns. Listening to
music with the cartridge approximately two thirds
across the record is the most reliable method,. If you
notice left channel mistracks, reduce the force and
unwind the bias screw, and if you notice the right
channel mistacks, increase the force by screwing
further in. If you do not trust your ears, a suitable
test record can be used to adjust the bias force
correctly and also your retailer can give assistance.
Arm Lead
Insert the 5 Pin DIN connector into the tonearm base
properly, clicking into place. Create a loop with the
lead for suspended turntables and lock it in place.
Connect the colour coded plugs and ground cable
to the amplifier.
Arm Lift Notes
The lift device does not require any adjustments, but
its proper functioning is contingent on the arm-tube
being level. Contrary to popular belief, variables
such as the height of the cartridge body do not
impact the calibration of the lift device. The factory
settings of the lift device are designed to work
optimally once the arm height has been accurately
set. To achieve this, the arm-tube must be parallel to
the surface of the record when the cartridge has
been lowered onto it. Should the lift or the cue bar
need service, a 1.27 A/F Allen wrench is supplied.
To operate the Lift device correctly, begin by raising
the lever beyond the vertical position to lift the
cartridge above the record's surface. Then, pull the
lever downwards gently, in line with the cue holder,
without applying excessive pressure or pushing it
any further as it can cause the internal cam to lock. If
the device stops descending before the stylus lands
on the record surface, you may need to lift the arm
lift slightly to assist the process.
Static Charge
Static charge can build up on the arm, causing noise
when touching the finger lift, especially in dry or air-
conditioned environments. Solutions include adding
moisture to the air with a plant, wiping the arm with
an antistatic fluid like L'art du Son, and avoiding
synthetic materials.
