Cartridge alignment null points. inner and outer null points perfectly when recording spins.

Cartridge alignment null points Because the inner null point is It can really only be correctly aligned at one position (overhang) and angle (offset) in the headshell to get tangency at both null points. Alignment Calculator Pro. The effective length, overhang, offset angle, and null points are then derived from the equations. So Rega TT/Rega cart at your budget will get you perfect alignment and VTA. An alignment protractor is a tool for aligning the stylus and cantilever of a turntable cartride as precisely as possible to two null points. When cart is put at the extreme back the cart comes closer to alignment but not perfectly. With a pivoted tonearm, it is possible to achieve perfect tangency at only two points as the tonearm travels in an arc across the record. I am wondering, knowing the exact null points for each tonearm, if its preferable to use these points for the calibration instead of Baerwald's fixing ones. You keep the cartridge square with the headshell--that sets the offset angle. A two-point cartridge alignment protractor can help achieve this tangency. This is an important step when setting up a record player. Good luck. 42 mm Null point alignment is the first and most basic adjustment to be made when installing a cartridge on a turntable. Then, move the cartridge forward, so the tip of the stylus will lower into the corresponding dot in the alignment tool. You’ll need to make two adjustments here. Null points depends directly not the kind of alignment but which outer/inner most groove distances we choosed as inputs in the equations/calculations. An alignment protractor is a tool for aligning the stylus and cantilever of a turntable cartride as precisely as possible to two null points. May 24, 2018 · During alignment of a new cartridge recently, I found there is no such two points where the cantilever is parallel to the lines at two null points of stevenson protractor even after moving the cart forward or backward in the headshell. Stevenson – Null points are 70. ) as a one and only solution: NO. Aug 11, 2019 · Each of these geometries provide different points on the arc where the stylus is tangential (null points) to the vinyl walls, providing the minimum tracing distortion. Apr 6, 2024 · 5) Null Points (Inner Null Point & Outer Null Point): The null points are the one that helps us in making the cartridge align. Jan 19, 2013 · Although this is a bit crude when compared with other more sophisticated alignment tools, namely protractors, setting up a cartridge using the Technics gauge in this manner is designed to give you alignment using the Technics null points of 58. I wanted to check to make sure the alignment is still all good, but I don’t remember exactly how to use the simple two-point cartridge alignment tool that comes with the Pro-Ject Debut Carbon DC. 801 and 113. Jun 10, 2021 · In any case, regardless how you set the overhang, you should still wind up with alignment at the two null points, so I would use that as the final check. Repeat until the stylus will sit exactly on both points without moving the protractor. Dec 12, 2017 · A commercially available cartridge alignment gauge can be used to align the cartridge such that it satisfies the tangency requirements at the null points. Aug 21, 2013 · After a number of years of setting up turntables from the afordable Thorens 166 to the massive Micro Seiki 8000 at a hign end stereo shop in Miami, Florida, with the resulting premature aging, the aforementioned hairlose, and guaranteed entrance into hell many times over with various alignment devices, I always like the concept of the "cart-a-lign" alignment device the most, but not the execution. You set the stylus at 52mm--that sets the arm length/overhang. Then loosen the cartridge and adjust its position until it’s correct. It sometimes can make noticeable differences in sound quality especially at the higher end and determines overhang which also controls the anti-skating force. Then, follow these steps: Simply check the offset angle of the cartridge body against the alignment tool. . Dec 3, 2020 · Then if you want to use a different cartridge, which I am on an RP8, you use one of the downloaded alignment protractors for the Rega arm with two measuring points and you are good to go - well, almost - then you might run into the dreaded shim or no shim debate. Jun 19, 2005 · You can use my Alignment Calculator to calculate null points for alternative inner and outer groove radii using either Stevenson, Lofgren A (Baerwald) or Lofgren B geometry. Dec 12, 2024 · Technically, you can use any alignment null points that work with the arm, so If the cartridge lines up on both points of a protractor, for example, then it will work. May 30, 2002 · On this page you can download free cartridge alignment protractors for quick and accurate alignment of cartridge / stylus overhang, offset and null points. Feb 12, 2007 · I then went to the Vinyl Engine and printed a generic Stevenon 2 point alignment protractor. 801 mm from the "centre" of your record and the outer 2-point protractors are universal protractors for turntable cartridge alignment that can be used with any record player (as long as the headshell slots are long enough for the chosen alignment geometry). 8 and 113. Without getting overly bogged down in technicalities, there are at least a couple of theories about where the null points should be, and so some gauges are slightly different than others depending on which the manufacturer thinks is best. 0 and 120. Here we can see the same condition as before, but the geometry is Löfgren B. We need to adjust our cartridge and headshell so that the stylus tip sits on both null points i. The equations for the various alignments determine your null points, are computed by inputting parameters into those equations. Aug 31, 2007 · Now lift the stylus and place it on the inner null point. They are not as easy to use as arc protractors, but knowing the exact pivot to spindle distance of your turntable will not be necessary. Most modern cartridge alignment gauges, such as the popular D B Systems DBP-10, are designed to produce correct Baerwald two-point alignment, although there are some that are designed using a Database Alignment Calculator Pro Overhang Shift Calculator. See full list on vinylengine. May 2, 2022 · Since 1979 I use the Baerwald protractor (66mm and 120,9mm null points) for cartridge calibration with acceptable results. 9 mm. These are called the null points. Do I keep the protractor in one place when setting alignment to the 2 null points or do I need to move the protractor for each null point alignment? I have just ordered some KAB mods (strobe disable, damper, 1/4 Nov 2, 2024 · Make sure to measure the pivot to spindle distance and use the correct one! Changing it in the protractor generator will shift the null points, so if you have to do that, you may want to enter an inner null of 68. This solution was derived by Löfgren in 1938 and derives a solution for minimal average distortion over the playing surface of the record¹. These two points are known as null points (points where there is no tracking error). 455 mm and outer null at 129. If we change these inputs null points will change it does not matters which kind of alignment we are using. 518 (the inner null point being 58. 775 mm instead of calculating the null points from the other specs. Those null points produce the published specs: Arm length, overhang, offset angle. Null points are indicated for the most common (Löfgren/Baerwald) alignment at the 3 o'clock position on the alignment gauge. Enter the published data for your tonearm to compare it's alignment to optimized alignment geometries. Baerwald calculated null points of 59 and 102mm should give the lowest average RMS distortion across the playing surface. Jan 26, 2024 · To calibrate the alignment of your turntable cartridge, you’re going to need some kind of alignment tool (similar to a ruler) and a screwdriver. 6 mm; Loefgren – Null points are 60.

In a radial tracking tonearm, there are only a couple of points when it actually is tangent (null points). You may also customise the alignments to be compared by entering alternative geometry for your tonearm, or by entering the data of different tonearms for Aug 22, 2019 · I recently swapped out my Ortofon 2M Red stylus with a 2M Blue stylus (keeping the 2M Red cartridge). Apr 10, 2017 · This protractor offers an extremely accurate way to align your cartridge using the Technics null radii of 58. If you are getting the "same" results at multiple cartridge positions in the headshell, then you are not being accurate enough in sighting the cantilever to the grid lines at the null points. Jun 19, 2008 · Ben, eventually I will be posting a thread on cartridge alignment, but in the meantime what you need to know is that it is concerned with the fact that there are two points in the swing of the tonearm over a record where the distortion is zero. There is no toggling between inner & outer null-points (this is why only the inner null-point is printed on Align it PRO). Nov 7, 2022 · That will make for the least distortion and the widest null points. inner and outer null points perfectly when recording spins. I'm not sure how to use it though. 325 and 117. The inputs are radii and PTS distance. 3 and 116. 5MM, resulting in an overhang of 15MM and an offset angle of 22 degrees, exactly as specified by Technics. e. Berwald – Null points are 66. Loosen your cartridge enough to allow it to slide back and forth with gentle resistance. Last edited: Dec 12, 2024 Reactions: Vlad Soare Oct 6, 2020 · Null points are a product of the PTS distance; not the other way around.
