Tracking might also suffer as the tonearm has to work a lot harder. (Cartridge/stylus guard mounted to tonearm + Tonearm) - counter weight (removed) = Total Effective Mass (Cartridge + Arm) Total Effective Mass - Cartridge/stylus guard weight = Tonearm Effective Mass Arms like the Vertere SG-1 have a sliding weight on the arm which allows fine-tuning of the tracking force, but also allows adjustment of the arm's effective mass. Arms above 25 grams of mass are high mass in nature (Eminent Technology, Dynavector). When used according to the instructions, and counterbalancing an ADC XLM-II, the effective mass (minus that of the cartridge) is around 4.5 grams, rising to about 6 grams—an ideal figure-when … Here was cited 9-11Hz, several say 8-12Hz, FKuzma says 6-16Hz. Another example is the calculation of the shallow impurity levels using a hydrogen-like model. But in trying to optimize the sound I need to know the tonearm resonance frequency which requires knowing the effective mass of the tonearm. Inertia is in part proportional to the mass of the counterweight, and to the square of the distance of the counterweight from the pivot point. Dear Badcap: Go up but the change in the effective mass will be small due that the counterweight is near the tonearm pivot. Barrel-shaped main counterweight. In the booklet he recommends a tonearm resonance frequency between 8 and 16 Hz, 11 being ideal. Tonearm Effective Mass H CF Step 5 V Step 6 Calculate the effective tonearm mass Enter mass of cartridge & fixings in grams If tonearm has detachable headshell, detach & weigh (without cartridge) Measure distance L from stylus to pivot in cm, or lookup effective length specification Remove counter weight and weigh it If I want to get closer to 10 Hz, I need to increase the effective mass of the arm/cartridge to 31.7g. Here is correspondence from Jelco, Haruo Uchida/Sales Manager. I did find some info however, and * A phono cartridge whose compliance is rated at 12 x l0ˉ6 or below, is considered low compliance. In the returned table, each column represents the cartridge and fastener weight as denoted at the top of the table, while each row represents the cartridge compliance as denoted by the value in the left most column. There is a lot of online tools and quick formulas for calculating tonearm resonance 1 , unfortunately these are mostly not correct – or they are correct enough, as they are based on estimates and approximations. Matching tonearm with cartridge: Compliance, effective mass, resonance frequency. SME 309, IV, IV-Vi, V, Triplanar, Graham). ... Tonearm effective mass calculation. Tonearm is mechanical, acoustical and electronic system. Database Database Tools Resonance Evaluator Record Equalization. We've decided to use our own ceramic headshell to minimize the headshell influence and to be conservative. To make music lovers enjoy a 16"tonearm, I developed the EMT 16" tonearm. Effective tonearm lenght in mm (from the tonearm pivot to the stylus) 304.8: Mounting distance (from the tonearm pivot to the spindle) 291.6: Offset angle (between a groove and the stylus direction) 18° Overhang in mm (from the spindle to the stylus) 13.2: Effective tonearm mass in grams 17,2 18,5 19,5 (including Alu headshell) 19.5 Where M is the mass of the arm, CW is the mass of the cartridge, FW is the mass of the screws, nuts, spacers, washers, shims and C is the compliance of the cartridge. Compare this to the Thorens TP16 Mk 1 tonearm which has a rated What do we know? Armtube material can suppress these parasitic accoustic vibrations (and of course, tonearm's effective mass depends mainly on armtube material). This likely limits the aftermarket options. A mass of 11-25 grams is considered moderate mass, and an arm rated at above 25 grams is considered high mass.

Sound depends on how many parameters were taken into account. If it is given without a cartridge and headshell, please enter their respective masses too. Re: Effective weight - how to measure We know the distance from pivot point to the tip of the tone arm (the effective length, 230mm for my Technics SL-1200). We've decided to use our own ceramic headshell to minimize the headshell influence and to be conservative. Also, for some of the newer/newest tonearms, there are NO data coming from the maker. Set the anti-skating device to the same figure as your arm’s tracking weight. Well, frequency, mass and compli- ance don’t tell us much, what we need is … The motor upgrade is usually as effective as upgrading to a Silver tonearm but this depends on the quality of your current turntable motor drive. Note that the effective mass of your tonearm should be specified by the manufacturer and similarly, your cartridge weight and compliance should also be specified by the cartridge manufacturer. Tonearms effective mass was propably ~14 g as there is still massive headshell connector metal part in tonearm tube and with 6g cartridge effective mass goes ~19g. The "Compliance" field is for the cartridge compliance. A mass of 10 grams or lower is considered a low mass arm. For full technical specifications, download RB330 User Manual below. Could be worth a try. We then added weight to the headshell to increase effective tonearm mass up to 25 grams. … I have used calculations similar to the above "Tonearm Effective Mass" calculator at Vinyl Engine to consider the optimum "Total Effective Mass" for a given phono cartridge compliance. Effective Mass. We're all good, this is a combination that works really well. Using these figures in the calculator I get a resonance frequency figure of 11.486 Hz. = ⋅ 1 2π where F is the frequency, M is the mass and C is the compliance. 236.5 mm.

These calculations include mobility and diffusion constants calculations. Desired Tonearm Mass Calculator: Cartridge compliance[cu] Desired resfreq [Hz] (Total)Effective Mass needed[gr] It is interesting to note that Poul Ladegaard of 'Bruel og Kjaer' determined empirically that the 'best" resonance frequency would be much higher (15Hz to 18Hz) than what is normally considered desirable. The effective arm mass is the mass in relation to the spindle that the cartridge sees. The latter is essential to hold the cartridge firmly so that as much musical groove information as possible is transformed to its electrical equivalent and fed to the preamp. Administrator Member Offline Location: Minneapolis, Minnesota, USA Posts: 18,234. c – compliance of the cartridge. Low mass arms* mate well with both moderately high and very high compliance phono cartridges. Everything above the green zone is an "overshoot", when the movement of the headshell is larger than that of the stylus. Effective length. If you need a significant change in the tonearm effective mass and if you can then you have to do it at the tonearm headshell position. ... the moment of inertia is m x r squared where m is the mass and r is the distance to its centre of rotation. The set of parameters of this system determine characteristics of tonearm. A tonearm whose effective mass is rated between 11 and 25 grams is considered moderate mass (e.g. The effective mass of a tonearm in combination with the compliance of the cartridge cantilever serves to determine where the resonant frequency of a given tonearm/cartridge match up will be. 3.5 out of 5 stars Best Sellers Rank Effective mass 12,7g (3009-R), 12,8g (3010-R) or 14g (3012-R). For a tonearm without a removeable headshell, leave the last field empty unless you use particularly heavy mounting hardware. Main counterweight can be split into two pieces to change the range of acceptable cartridge mass (two different removeable pieces are available : 64g, 77g). The stylus might hit the hard stops on warped/excentric LPs. Tonearm Effective Mass H CF Step 5 V Step 6 Calculate the effective tonearm mass Enter mass of cartridge & fixings in grams If tonearm has detachable headshell, detach & weigh (without cartridge) Measure distance L from stylus to pivot in cm, or lookup effective length specification Remove counter weight and weigh it For a tonearm without a removeable headshell, leave the last field empty unless you use particularly heavy mounting hardware. The resonant frequencies calculated by the evaluator are applicable only to those measured at 10Hz. To use the resonance evaluator simply enter your tonearm's effective mass in the text box and press submit. Main counterweight position can be adjusted by turning small knurled dial at rear of arm. Ilkka, "Luckydog" made a tonearm effective mass calculator over at vinylengine.com. Effective mass is the moment of inertia divided with distance to spindle (or Effective Length) to the power of 2: EM = MI / EL 2 Where MI is Moment of Inertia and EL is effective length. Jelco publishes its effective mass (13.5g), so that should make our calculations easier. Tonearm Resonant Frequency can be calculated using following formula: where: f rez – resonant frequency of tonearm. The confounding reports of apparent tonearm/cartridge mismatches that sound great have me thinking about the quality of the data for compliance and tonearm effective mass that we start with. This topic bothered me a long time, especially when it seemed more or less impossible to find specific data about the effective mass of the stock Lenco (L75) arm. The Wand Tonearm, Turntable and Phono Stage Data. ie. Designed using the latest 3D CAD & CAM technology, the new RB330 is the culmination of more than 35 years of tonearm design experience. The other, and usually preferred, alternative is to simply use a tonearm that already has enough effective mass to adequately operate the suspension of a low compliance MC cartridge. Say, a DL-103 on a light arm. variable tonearm mass with 2 different counter weights. The effective mass for conductivity calculation is the mass which is used in conduction related problems accounting for the detailed structure of the semiconductor. A small overshoot at about 5 Hz should be harmless. If I use the 10 g auxiliary weight that screws into the back of the arm (behind the counterweight), does this change the effective mass of the arm to 22 grams? The effective mass of the Jelco 750D 9″ tonearm with the standard headshell but without cartridge is 13.48g.. Acceleration: your line should be in the green zone. Return and secure the tonearm. Main parameters are: Effective length, Effective mass, Moment of … Note that the effective mass of your tonearm should be specified by the manufacturer and similarly, your cartridge weight and compliance should also be specified by the cartridge manufacturer.
