BAERWALD ALIGNMENT PROTRACTOR PDF

Click to expand So have I. All we are trying to do is get the cartridge tangent to the record groove at two points and keep it close to that for the rest of the album. For years I used the first decent alignment gauge out there, the DB Systems protractor , which allows you to set up your cartridge off of the recommended alignments like Baerwald and Lofgren. It also will read how far off of tangency you are at any point on the record. The tonearms were too short.

Be sure to choose a protractor that matches your arm or turntable, as the accuracy of these protractors relies on the pivot to spindle distance being correct. Which Protractor? There are 2 popular alignment families, known as Baerwald or Lofgren A and Stevenson. The 2 alignment geometries are calculated to minimise tracking error and distortion. Lofgren A or Baerwald alignment spreads the distortion across the surface of the record, resulting in the lowest average distortion figures.

Stevenson alignments are optimised for zero tracking distortion in the lead out groove of the record at the expense of slightly higher distortion everywhere else.

In reality the distortion figures are so low as to be of little issue. If your turntable manufacturer specifies an alignment, it is best to stick with their recommendation. If not, a Lofgren A protractor usually offers the best performance across a majority of LP records. Technics , Technics Alignment This protractor will align a cartridge to the factory Technics alignment, the same that is achieved when using the supplied overhang gauge.

This protractor offers an extremely accurate way to align your cartridge using the Technics null radii of When aligned, your cartridge body should be parallel to the headshell, with the distance between the tip of the stylus and the rubber washer at the rear of the headshell exactly 52MM.

When aligned, the cartridge will sit further forward in the headshell, angled slightly inwards. This alignment offers less RMS and peak distortion than the factory Technics alignment, though you may find the difference to be subtle at best. I prefer the Technics alignment. This protractor will work with any tonearm with a mounting distance of MM. Most Rega arms follow the MM mounting standard, including the RB, , , , , and many others.

Other Protractors Other protractors can be downloaded from the Vinyl Engine. Creating Your Own If you know the pivot to spindle distance if your arm, creating your own protractor is a simple task. This Arc Template Generator will calculate an arc protractor like those above based on your tonearm mounting distance, desired null radii and any of the 3 common alignment families.

Strobe Discs These discs will allow you to check the speed of your turntable. Again, they should be printed to scale, and be sure to use the disc suitable for the electricity supply in your country 50Hz in the UK. Better results can be attained using the Turntabulator app for iOS.
