You may also choose "Save as PDF" in the printing dialogue instead of a printer to download and save your custom phono cartridge alignment protractor to your hard drive. The manufacturer recommended overhang and offset angle can be ignored. Please note that each combination of null points and alignment method will result in a different overhang and offset angle. If it does not, it will be necessary to adjust the printer correction factors accordingly.

The outer square should measure exactly 190 x 190 mm. Make your choices, calculate the specifications of your protractor or generate one right away by clicking on the buttons and print out the arc protractor template at 100 % scale (to be set in the printing dialogue). Note that when choosing this option, the groove specification setting will make no difference.

This is particularly useful if you need to match the stock alignment of your turntable or if you would like to experiment. custom allows you to set your own null points or calculate null points for a known geometry.AP™ is our proprietary alignment with reduced tracking distortion at the inner grooves (where tracing distortion is a problem) and increased tracking distortion at the outer grooves (where tracing distortion is low).Löfgren B will give you the lowest RMS distortion, but increased error at the inner and outer grooves.Baerwald (also known as Löfgren A) is generally considered to be the best compromise that minimizes distortion across the record and keeps the distortion at the inner and outer grooves low.Stevenson optimizes for the least inner groove distortion at the expense of increased average distortion.

They all try to optimize tracking distortion, but in different ways: Which alignment you should choose again depends on your personal preferences. If you know what you are doing, you may also enter custom values.īased on the groove radii, the null points are calculated according to the alignment method. For easier measuring, you may print out our record ruler. So measure a couple of records with a narrow dead wax and choose wisely. This is particularly critical for the inner grooves, as distortion increases significantly beyond the inner null point. DIN and IEC both have been specifying a larger outer groove radius of 146.3 mm since 1964, but this will not make much of a difference.īut which of the three standards should you choose? It depends on your records! Tracking distortion will be minimized in the specified modulated area.

They were chosen to keep the generator compatible and comparable with other protractors and calculators. These are the most commonly used dimensions.
#PROTRACTOR CALCULATOR MANUALS#
Most record player manuals will give you a specification for effective length and overhang. Pivot to spindle distance is the only variable you actually need to know. The turntable input field sets a name for the template, allowing you to identify for which model the protractor was generated. The arc protractor makes turntable setup a lot easier. With 2-point protractors, both are set at the same time, which can be confusing and time consuming.

The great advantage of an arc protractor is that it separates the overhang adjustment from the offset angle. Unlike 2-point protractors for phono cartridge alignment, which can be used with any turntable, this generator puts out an arc protractor template specifically for your record player.
