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.
#Circular protractor generator
They were chosen to keep the generator compatible and comparable with other protractors and calculators. These are the most commonly used dimensions.
JIS (S8502-1973) is a Japanese standard and uses a slightly larger inner groove radius than DIN (57.6 mm) and the largest outer groove radius of the three (146.5 mm).Both use the same outer groove radius (146.05 mm). IEC (IEC98-1958), an international standard, the largest (60.325 mm).DIN (IEC 98) is a German standard and will use the smallest inner groove radius (57.5 mm),.There are several standards for the radii of the inmost and outmost modulated (i.e. Please note that actually measuring the distance may give you a more accurate result. Simply subtract overhang from effective length to get the pivot to spindle distance.
#Circular protractor 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.
