Description:

The Trackabillity provides information on the sampling characteristics of your tonearm / cartridge combination. The higher the value achieved, the better the relevant tonearm / cartridge combination is to scan difficult groove modulations without distortion. Amplitude accurancy +- 0.1 dB


Tracking Ability Test

If you´d like to learn more about the tracking abilities of your tonearm-cartridge combination,
this test is a perfect tool. We cut a 315 hz signal and increase the amplitude in steps of 10 (1 =
0.001 mm) from 50 to 100. The higher the value, the better your tonearm-cartridge combination
should be able to track even heavily modulated grooves without audible distortion.
Please make sure that your turntable is pefectly leveled, the azimuth and vertical tracking angle
are properly set (We recommend using the Clearaudio Azimuth Optimizer). Start this tracking
ability test by using the minimum recommended tracking force (antiskating set accordingly) and
gradually increase both values until your cartridge is tracking 80 in both channels. Attention: Do
not eexeed the manufacture´s recommended maximum tracking force to prevent any damages.
Keep in mind your records more than a marginally raised value would do.
If there is more distortion in one channel than in the other, please vary the antiskating force until
both channels sound equally clean. Once the test signal begins to distort in both channels, the
tonearm and cartridge are no longer able to track the grove correcty. It is a very good result if a
cartidge tracks 80 without distortion. The test signal of 90 and 100 are extrem amplitudes, which
never show up in cutted music signals but if tracked by a cartridge it indicates a safety margin.


Azimuth Adjustment with the Clearaudio Azimuth Optimizer

To experience music reproduction at highest quality levels from analog records it is required to
achieve optimal positioning of the picked stylus in the record groove.
There areserveral possibilities to accomplish this:
a) adjustment by visible contral,
b) adjustment by listening,
c) adjustiment by the use of measurement equipment.
Possibility a) is limeted to the estimation by eye and turns out to be unrealistic for the following
reasons:
The lateral tracking balance is determined by the tracking points of the stylus relativ to groove
sides. This must not be examined under static conditions but dynamically under influence of all
acting forces when tracking a cord. The friction pulls the stylus tangentially producing a vertical
component which changes the VTA and reduces the tracking force. A skating force that is not
ideal compensated acts in a radial direction and not only causes diffenrent pressure to the right
and then to the left groove sides, but “riding-up” the 45°-slope further reduces the tracking
force.
Deprending on diffenrent tonearm constructions, possible additional torisonal force may act upon
the cantilever. All of these influences let the adjustment by visible control only be a second
choice.
At any time adjustment by listening was favored by HIFI purists who experienced drastical
improvements of sound when experimentally finding azimuth deviations from visual perpenticular
orientation by iterative trails and numerous listening sessions. This method, however, is very time
consuming.
The most exact and unbiassed method is possibility c) by using measuring equipment. To avoid
the necessity of expensive equipment, clearaudio developed the Azimuth Optimizer which
requires an appropriate test record with a lateral mono signal (see side B)
In the clearaudio research laboratory we determined that the adjustment of the azimuth most
obviosly influences the level differene between right and left channel of a lateral mono signal,
which therefor can be used for indication (see diagram)
From the diagram you see that the best orientation of the stylus is achieved when the curve of
diffenrence between right and left channel averages around 0dBV (the LCDisplay of the Azimuth
Optimizer fluctuates around zero).
