Well, the easiest way to operate the spreadsheet is by using the L�fgren "A" or "B" calculator at the top of the spreadsheet page. The calculator has three yellow input cells and six green output cells. Inputs are effective length, innermost groove, and outermost groove. Outputs are angular offset, linear offset, stylus overhang, pivot-to-spindle mounting distance, inner null-point, and outer null-point. The default or initial input values are The output values change in accordance with the equations listed in the instruction area below the graph when new numbers are entered into any of the yellow input cells. The graph is a visual representation of the columns of numbers on the left, which are a function of three specific tonearm parameters, effective length, angular offset, and stylus overhang as displayed in the tan colored cells, A3, B3, and C3. These are also spreadsheet input cells, but initially they are linked to the corresponding calculator cells, I3, O3, and Q3 so the calculator controls the entire spreadsheet.
However, the tan colored cells may easily be unlinked from the calculator simply by entering numbers into them. If this is done, the calculator operates autonomously from the rest of the spreadsheet. The graph and the rest of the spreadsheet are controlled by inputs to cells A3, B3, and C3 only. One reason for unlinking the calculator might be to evaluate a tonearm's geometry by inputting effective length, angular offset, and stylus overhang directly into cells A3, B3, and C3, respectively. You'll find some interesting designs floating around out there with alignment geometry's based on something entirely different from either L�fgren "A" or "B. For advanced spreadsheet users, the Excel "Solver" function is a very powerful tool that can be used advantageously with this spreadsheet. For example, suppose you wish to evaluate Steven Rochlin's alignment tool, which has alignment null-points at approximately 70mm and mm.
You could ask "Solver" to find new innermost and outermost groove radii that would yield Steven's alignment null-points, and you would also get a graphical representation of Steven's tracking error and distortion curves. There are many ways "Solver" can be used to enhance and expand the capabilities of complex spreadsheets. As a word of caution, only six cells on the spreadsheet should be used for entering numbers. They are the three yellow cells, I3, J3, and K3 in the calculator at the top of each page, and the three tan cells, A3, B3, and C3, which control the graph and the rest of the spreadsheet. Please do not enter numbers into any other cells; otherwise you may destroy important equations that enable the spreadsheet to function properly.
As an additional precaution, I recommend you archive a copy of the spreadsheet and always use a different working copy, just in case something goes wrong and you want to return to the original. Other than that, have fun calculating. HINT: Right click your mouse on the link above and choose Save Target A s Quick Links. Audiophile Review Magazine High-End Audio Equipment Reviews.

If it does not, it will be necessary to adjust the printer correction factors accordingly. 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. Another way to save your alignment template for future use is to simply set a bookmark in your browser. All the parameters of your arc protractor are stored in its URL. To share your protractor with others, we recommend sharing the link to the calculation results instead of the protractor link, as this will allow for tweaking the printer scale settings.
To protect your stylus, printing the template onto glossy photo paper is recommended. You may also stick pieces of clear parcel tape to all points to which you lower your stylus, or laminate the alignment protractor. Now cut or punch out the spindle hole as accurately as you can. Some prefer to perforate the outline of the spindle hole with a needle and then punch out the center, others use a sharp knife and a straight edge or metal ruler. Cut off the excess paper along the dotted line and place the protractor on your turntable. First, the overhang is set by adjusting the cartridge position so that the stylus tip traces the arc on the template perfectly: Set the stylus on the arc line near the edge of the record. Then lift it and set it down close to the spindle.
If it comes down right on the arc, the overhang is set correctly. If it is short of the arc, overhang needs to be increased by moving the cartridge forward in the headshell. If it is beyond the arc, decrease overhang by moving the cartridge backwards. If the slots in your headshell are too short for setting the correct overhang, you will have to choose a different alignment strategy with a shorter or longer overhang. If it turns out to be impossible for the stylus to trace the arc, your measurement of the pivot to spindle distance or the print scale may be off. Once the stylus follows the arc, the overhang is set and the cartridge alignment protractor is perfectly placed on your turntable. It must not be moved for the rest of the procedure.
At this point, it is best to move the cartridge back a tiny bit in the headshell. This is because a stylus placed on a spinning record will be pulled forward a little more than a stylus that is placed on a stationary record or protractor. By moving it back, you ensure that the stylus will be right on the arc when a record is spinning. Set the offset angle by aligning the cartridge body or cantilever to either grid. The stylus tip needs be lowered exactly to the center of the grid for a good result. When aligning a cartridge body with a flat front, greater accuracy can be achieved by taping a pencil lead to it. To be able to align the cantilever, it is necessary to decrease the tracking force to under 0.
Make sure to look at the cartridge in a straight line to avoid parallax error. This is easiest to see from a low angle. A magnifying glass or phone camera can be of great help here. Set up enough lights to eliminate any shadows under the cartridge. Activate the grid in your camera app and make sure the horizontal lines of the protractor grid are parallel with it. The vertical line to which the cantilever is aligned should be parallel with the vertical grid lines. Please note that the cantilever may deflect when a highly compliant cartridge is lowered onto the protractor, especially if the surface is rough and the stylus cannot move.
Lowering the vertical tracking force should pretty much elimimnate this issue. If it does not, it is best to keep the stylus just above the protractor and to not lower it down or to align the cartridge body instead of the cantilever. Once you are happy with the alignment, you may double check on the other grid. Make sure that the overhang is still set correctly. Do not forget to set the vertical tracking force and anti-skate back to their correct values when you are done.
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. The great advantage of an arc protractor is that it separates the overhang adjustment from the offset angle. With 2-point protractors, both are set at the same time, which can be confusing and time consuming. The arc protractor makes turntable setup a lot easier. The turntable input field sets a name for the template, allowing you to identify for which model the protractor was generated. Pivot to spindle distance is the only variable you actually need to know. It varies from turntable to turntable.
Most record player manuals will give you a specification for effective length and overhang. Simply subtract overhang from effective length to get the pivot to spindle distance. Please note that actually measuring the distance may give you a more accurate result. There are several standards for the radii of the inmost and outmost modulated i. recorded grooves of an LP record. Simply choose the standard you prefer:. These are the most commonly used dimensions. They were chosen to keep the generator compatible and comparable with other protractors and calculators. DIN and IEC both have been specifying a larger outer groove radius of But which of groove dimension standards should you choose?
It depends on your records! Tracking distortion will be minimized in the specified modulated area. This is particularly critical for the inner grooves, as distortion increases significantly beyond the inner null point. So measure a couple of records with a narrow dead wax and choose wisely. For easier measuring, you may print out our record ruler. When optimizing for 10" or 7" records or if you own mostly modern records with a very wide dead wax area, other groove dimensions can be entered by choosing "custom". When optimizing for 7" as well as 12" records, you may want to consider this. Based on the groove radii, the null points are calculated according to the alignment method. Which strategy you should choose again depends on your personal preferences.
They all try to optimize tracking distortion, but in different ways:. Please note that each combination of null points and alignment method will result in a different overhang and offset angle. This is normal. The manufacturer recommended overhang and offset angle can be ignored. When printed, the outer square should measure exactly x mm. If it does not, it will be necessary to adjust the printer correction factors accordingly.
