The SMARTractor

‘Mating ultra-precision with the utmost ease and swift operation’

SMARTractor and now SMARTractor XL

With the SMARTractor XL (NEW) the user can precisely align and position tonearms with up to 410 mm P2S / mounting distance!!

Tonearms like Kuzma 4P 14″ and some other extremly long effective length tonearms can now be aligned with the SMARTractor with ease.

While the UNI-Protractor represents the most universal and versatile phono alignment tool ever introduced in high-end audio, it is an instrument which – due to it’s complexity and versatility – appeals more to professional users.

The serious audiophile who is interested in aligning – ifonly periodically – his analog front-end to the utmost precision does look for precision which comes handy and which is easy to operate.  To answer this request we have designed the SMARTractor – a direct off-spring of our UNI-Protractor.

The SMARTractor brings the same unparalleled precise tangential alignment for which the UNI-Protractor earned it’s laurels – PLUS the 0.05mm precise mounting distance measurement of the UNI-P2S.

‘A Unique bundle of features’

The SMARTractor comes with 5 (five) tangential curves combined in 1 (one) template.

The SMARTractor’s template is made from 3mm (= same thickness as 180 gr LP) strong premium grade german XT mirrored acrylic supplied by Evonik.

No-error-possible single-point alignment with 3mm deep parallax (for ALL helping lines) – an extreme precise, easy and fast alignment.

Super easy to use, with 1-point fixed setting for every tangential curve.

All alignment lines are cnc-laser cut hairlines.

Incorporates real glass aluminum-frame magnifier with automatic focus jig for unrivaled precision.

All 5 tangential alignments are based on true triangular positioning and thus are independent of effective length and thus suitable for ALL pivot tonearms, no matter what their effective length or mounting position.

The SMARTractor further comes with in-built direct mounting distance – P2S -measurement with 0.05mm accuracy.

The 5 tangential alignment options  include the old audio phono standards set by Loefgren and Baerwald in the late 1930’s and 1940’s in both – IEC and DIN – norms.

Uni-Din is an all new tangential curve which is the latest calculation and the first one which does really take into account the special requirements and circumstances of a stereo stylus tracking a non linear stereo groove with increasing differences between the two groove walls.

The result? – real sonic benefits!

In the last 2/3 of the record’s groove, the UNI-DIN curve offers significant (18-45%) less average – as well as less total! – distortion than Baerwald or Loefgren.

Sonically this gives you less stress on human (female)voices, more subtle details, less “grain”, increased “air”and considerable more “headroom” in critical passages and especially so in climaxes.

Rest assured – you’ll love it, once you’ve heard it’s direct results and merits.

The UNI-DIN tangential alignment is available only in the SMARTractor and the UNI-Protractor.

Why 5 different options for alignment of cartridge/tonearm?

The vast numbers of tonearms introduced in the past 40 years not only employ a large number of different concepts, but also great diversity in alignment geometries.

Furthermore it makes a significant difference whether the record we want to track with best possible results is a modern pressing with a very long run-out/lead-out (‘unmodulated groove’ or ‘dead wax’), or whether the record’s groove is cut close to the paper inner label.

The latter scenario is often found with records made in the early stereo years from 1958 up till 1974.

The SMARTractor takes into account the diversity of geometries found in pivot tonearms – as well as the different situations in records past and present.

The SMARTractor offers the best possible tangential curve for every request, for every pivot tonearm – as well as for every record collection, and it makes sure that the serious audiophile gets the most perfect, utmost precise alignment possible.

Ultra precise alignment results is achieved with ease and free of any possible error.

No in-deep knowledge nor any special manual skills are required to learn how to accurately set up your own cartriges.  A steady hand is recommended.

Setting up your analog front-end with unparalleled precision- and with the BEST SONIC results obtainable – is only a matter of a few minutes when using the SMARTractor.
