dynavector 507 manualDV507 has more theoretical improvement as well as the more conventional in the actual use. DV507 is a specially designed tone arm which can reproduce the signal on disc without influence caused by disc warp. In order to perform its unique specifications Including bi-axis inertia separation to vertical and lateral directions, the DV507 has a more complicated structure compared to conventional tone arms. This can easily be obtained using the enclosed paper template. Test the arm in the mounting hole. Mark the position of the DV507's small fixing holes on ARM BASE, remove the arm and then make three small holes at these positions using a gimlet or sharp instrument. The arm can now be secured to the board using the screws provided. If the Damper Plate moves freely through the Damper Magnet slit no further action is necessary. If, however, the plates' movement is restricted by touching or rubbing on the magnet you will need to gently bend the plate with your finger to avoid obstruction. Avoid knocking or touching the plate after it has been set. Be careful not to scratch the painted surface. (see Fig. 3). In the horizontal plane it has very heavy inertia careful balancing with the main weight is therefore required in order for the main arm to rotate smoothly. The actual DV headshell weight of 15 grams should be added to the cartridge weight for selecting one from these three sub weights. In this case please refer to the right table. For instance when the total weight is 20 grams, choose the sub weight A, and adjust the top end of main weight to the line of 20 of scale A (see Fig. 5). Adjuster scale is graduated by 0.2grams and between graduation marks, too, adjustment is done progressively in proportion to adjuster screw advance. This is not by the defect of the bearing but for the damping, effect for the smoother performance at mid frequency range. Afterward fix this screw rigidly.http://cptcla.org/userfiles/corporate-identity-manuals-david-e-carter.xml

DV507MKII is a high-performance tonearm with many advanced features, which enable it to transmit signals on the record precisely through a cartridge. The original mass-separation or 'bi-axis inertia' arm was the 505. The 507 MKII is the latest development of that revolutionary design with greatly enhanced performance and ease of use thanks to a major redesign.

Mounting to the turntable Use the supplied mounting template for the DV507MKII. Drill a 30mm diameter hole on the arm board of the turntable 226 mm away from the turntable spindle center. This cancels potential difference between right channel and left channel giving the best possible transmission of the signal. Insert the 5-pin plug of the tonearm cable into the output connector of the tonearm and connect the RCA plugs of the tonearm cable to the input of the phono stage or the pre-amplifier. 6. Page 5 b) Overhang alignment Overhang is the distance from the spindle center of the turntable and the stylus tip of the cartridge when the tonearm is rotated over the spindle. The overhang of 15mm has been designed on the 507MKII so that minimum tracking error is at the inner track of the record. NOTE: You can easily check the overhang by using the mounting gauge supplied - see above, which fits between headshell and arm. When the stylus rests on the zero point then overhang is perfect.

NOTE: This adjustment is not super critical if the turntable and arm are level (as they should be). 6-5. Vertical Tracking Force (VTF) adjustment Place the correct sub-weight onto the sub arm. NOTE: When lowering the stylus onto the record, the cueing point may drift a little toward the outer groove of the record. This is because of anti-skating force, it is not defect with the arm lift.

As it is a bi-axis inertia controlled tonearm the DV 507, no matter the type of cartridge can trace the music signal grooves cut in the recording with extreme accuracy. The DV 507 also provides superb trackability on warped recordings. Resolution and musical detailing are quite remarkable. It is machined from aluminium alloy and has an EIA standard connector. This allows the cartridge to be rigidly mounted and the azimuth adjustment.The 5 PIN connector conforms to the DIN standard.First, there is the need to support the cartridge so that the transfer of the cantilever motion accurately mirrors the audio signal. Secondly, it must maintain an excellent tracking ability for warped records since few records are perfectly flat. These requirements can conflict with each other. However, the bi-axis tonearm provides an effective solution to the problem. The DV505 and DV501 have enjoyed an excellent reputation in the European audio market since being awarded the Design and Engineering Award at C.E.S. Chicago in 1977,1982 and 1985. The DV507MKII has important sonic improvements as well as being easier to install and use. It includes all of the technology of our tonearm design developed since the DV505 and 501. In contrast, a conventional tonearm has only one arm which moves both horizontally and vertically. This is called a gimbal type tonearm and the inertia for both planes is the same. The DV507 bi-axis tone arm has a large inertia for horizontal movement and a very small inertia for vertical movement. We shall now explain the reasons why this is advantageous. It is well known that a cartridge generates an audio signal by the differential motion between the cantilever and the cartridge body. Consequently, if the supporting point of the cartridge (the tonearm) vibrates, the tonearm motion affects the audio signal. In these conditions, the signal, which causes the tonearm to vibrate is of low frequency and large amplitude. In the currently used 45-45 stereo record cutting procedure, low frequency signals are almost entirely recorded in a horizontal direction. This means that the low frequency signal, which can cause vibration in the tone arm, exists only as a horizontal force. The tonearm therefore must have sufficient effective mass and rigidity in the horizontal plane in order to provide a stable platform for the cartridge. On the other hand, for the mid to high frequencies, the effective mass of the tonearm should not be too large since the combined mass of the cartridge and the head shell need to be taken into account as well. In particular, where records have a warped surface, the vertical effective mass needs to be small enough to ensure a good tracking ability on such surfaces. To summarise, the tone arm should have a large effective mass and enough damping in the horizontal plane and at the same time a small effective mass in the vertical plane. These conditions are almost impossible to achieve with a tone arm of conventional design using a simple gimbal pivoting system. To solve the problem, Dynavector designed a bi-axis, inertia controlled tonearm where the shorter and lightweight vertical sub arm is placed at the end of the horizontal main arm. This is the special feature of our design. In this system, a curved rod attached to the rear of the arm is mounted in a magnetic field supplied by two powerful neodymium magnets. Any minute movement of the rod, due to an undamped arm resonance, causes an eddy current to be induced in the rod, which in turn interacts with the magnetic field to return the system to its rest state. As already demonstrated in our DV505 and DV501 arms, this damping system is highly reliable as there is no performance loss with extended use. Expensive Neodymium magnets are employed because of their superior properties and the thicker copper damping plate used gives a much better damping action. This dynamic balance system maintains an unvarying tracking force regardless of any record warp. Tracking force is easily adjusted by turning a calibrated dial. High precision, stainless steel bearings are used in the sub arm. By having a long span bearing support, the dynamic sensitivity has been further improved. The vertical shaft to which the sub arm is attached has a smooth bearing action, an important factor for the arm's operation and sound reproduction quality. Thus tracking ability has been significantly improved and the bearing mechanism performance enhanced. This is called multi-resonance or anti-resonance. To eliminate such unwanted resonances, a dynamic damper has been installed in the bottom of the sub arm. This solution was developed after much theoretical consideration and experimentation. To adjust the VTA (Vertical Tracking Angle of the stylus to the record surface) more easily, a height adjusting lever is provided. The height can be adjusted more precisely than with other systems, within a range of 0 to 7mm. The anti-skating force is set using a dial indicator. The anti-skating force can be adjusted even while playing a record. It is thus easy to install on most turntables. A fixing hole with a diameter of 29 mm is needed to install the DV507MKII on the turntable board. The distance from the centre of the fixing hole on the arm board to the centre of the turntable spindle should be 226 mm. With head shell: max 326 mm.

The table is coming back from ZU audio with a new ZU DL103 catridge and their Xaus tonearm cable. While waiting for the table, I happened upon a really good deal on a DynaVector DV505. It looks cool but it appears complicated to set up and use. I'm somewhat of a novice and just joined AudiogoN. Any opinions about the DynaVector arm would be appreciated. By the way, Sean Casey and his crew at ZU audio just blew me away with their level of customer service.

I owned a 505 some years back and had no issues with it other than it's unusual appearance and massive overall weight. The biggest problem with the Dynavector is the short (vertical axis) tonearm which is especially sensitive to VTA and record warp due to it's ultra short length. The plus side of the Dynavector is the high mass arm for the horizontal plane, which provides very robust bass with most cartridges I've paired with it. Your SME is a good arm and the Dynavector is a good arm. I suspect cartridge matching, tonearm cable and other variables could cause a person to vote for one or the other based on their own preferences. If you want to move way beyond either of these arms you would have to buy a newer design such as the SME 312S or the Triplanar. Again, just my opinion.Albertporter. in your first paragraph you find the arm with no issues other than its appearance and weight.in the second paragraph you chastise it for its ultra sensitivity to VTA and record warp.It has adjustments for vertical tracking force (VTF), azimuth, vertical tracking angle (VTA) and anti-skating. Unlike some other arms, these settings stay for a long time. The Dynavector tonearm has seen various upgrades throughout the years, so I'm not sure how the older versions compare to the new one. The arm looks complex because every setting has its own dial. These dials stick out from the main arm structure. This is what makes setting this arm a breeze. This is a link to where you can download the instructions for the 505 and other Dynavector products.

How is this odd? mechans Details Discussions Posts This discussion Message User 3,048 posts 05-18-2008 12:50pm Edit Delete The comment I have is that I think Albert is right. I own a Dynevector XX20 H.O. and it is right on top of the vinyl no VTA adjustment unipivot bearing. The detail is fantastic. So much so that after carefully washing the record with great fluids and brushes on the Dyne machine 3 times it shines like a mirror. Then I play it.Thee noise flor is ok but every dust mite or a piece whatever microscopic debirs that alit on the record during the time i got it going sounds like a firecracker. It is too much for me. I use a highly mdded ARC SP6B with very good NOS and current tubes. Can you explain further just what it is you are talking about. Do you own a Dynavector tonearm to go with your DV XX20 cartridge. I ask because I too have some interest in purchasing a DV tonearm and am following this thread. This is the way that I use it all the time in different TTs and works really fine and you can mount it evrywhere in any surface type. Regards and enjoy the music. Raul. genesis168 Details Discussions Posts This discussion Message User 396 posts 05-18-2008 6:04pm Edit Delete As with any arm, there are different sets of tradeoffs in all designs. The Dynavector is no different. Is there a perfect arm. I cannot really answer that. Yes, the short armtube is more sensitive to VTA changes on warped records but was there for a few specific reasons. The short and light armtube tracks almost anything without a hiccup. Because of the low vertical mass, the armtube and the cartridge works as one. The arm can follow the record profile (no record is perfectly flat) without a hitch hence the great trackability compared to longer tonearms. It will also take the work load off the cartridge's suspension (as the suspension is not fighting a heavy armtube)making the cartridge work more efficiently and track quieter. Lastly, setting the arm from scratch is a breeze. It is highly adjustable and a very flexible arm to use with a wide range of cartridges. If you have the opportunity to get a 505, go for it. It's a great tonearm and way ahead of it's time.I see the table turning, but with the ring clamp and spindle clamp.or with a vacuum system, the arm moves across the record with grace and alacrity. I just looked at the stylus, and it too seems not to move. I suppose if your records are warped and in need of Dyna's answer to tracking, you should get it. However, eliminating the warp in the first place enables the cartridge to sit in the groove and not be tossed around at all. This is set up on the Raven One (separate motor) together with the Benz Micro LP. In relation to the set up, I was so surprised that set up was a breeze. This is the most manual of the Dynavector tonearms, there is no dial to adjust anti-skate and tracking force. Tracking warped LPs does not present any problem,perhaps this is due to the short armtube, one hardly sees the stylus riding the LP up and down.In their literature DV does make the dual and to me internally contradictory claims for both qualities. In fact, they quote the effective mass (with their standard 15-gram headshell) at 25 grams! (That's high, folks.) As I understand the concept of effective mass, it is a measure of the inertia of the tonearm, which along with the cartridge and hardware mass interacts with the compliance of the cartridge to determine the LF resonant frequency. Mind you, the high effective mass is what you want with a low compliance LOMC, and this is what makes me interested in the DV tonearm, in fact. It certainly is a beautifully made and well thought out product.The Dynavector consists of two separate tonearms, a very unusual design allowing for low mass in the vertical plane and high mass in the horizontal plane. That very short arm (the low mass) is also subject to VTA errors, due to ultra short pivot point. The good news is the high horizontal mass makes for great bass with many cartridges. It helps to look at a photograph. The Dynavector is such a departure from other designs it's not easy to understand unless you've owned one.The Dyna is 2 arms in one. One for horizontal movement and one for vertical movement. Theoretically, that is what is most desired in a tonearm but has it's own working quirks like Albertporter mentions. Designing a tonearm like this, you can achieve very high effective mass horizontally and low effective mass vertically. It's hard to explain. You have to see how it works. Idf you see the picture, you can figure it out. Now, the 505 has a low effective mass ( sub-arm ) against the main arm. The tonearm is required to fulfill two functions so that the cartridge can reproduce the exact signal from the record groove. One of these is to hold the cartridge stationary at audible frequencies so that the stylus and cantilever motion is translated into a music system without losses. The other is to allow the cartridge to track warped records. These require totally contradictory properties from the tonearm and so all conventional tonearms are a compromise between the two. However, a very reasonable solution exists in the bi-axis tonearm. The bi-Axis inertia control tonearm is in effect two arms in one - the main arm beam has an effective-mass that is 3 or 4 times higher compared with conventional tonearm but moves only horizontally. On the other hand, the sub-arm has a lower effective- mass than any conventional tonearm but moves only in the vertical direction. Regards and enjoy the music. Raul. lewm Details Discussions Posts This discussion Message User 8,161 posts 05-19-2008 8:17pm Edit Delete I get it. I am especially intrigued by Raul's mention that it can be used with no drilling, by fastening it to the mounting board with double-sided tape.The 507 is another story. You need to drill to install the 507. Hope this helps clear things out.In my research I came across another curiosity. Dynavector uses Stevenson's alignment rather then the more common Lofgren or Baerwald. Is this something to consider when choosing an arm or are the differences really just academic.Null points are at 60.1mm and 116.5mm. I don't know what alignment method this is, but I've tried Loefgren and Baerwald and both worked fine for me. I currently have it set up based on the template and the cartridge mounting gauge provided. I use what was provided with the arm because I find the cartridge mounting gauge very convenient and it allows you to set up the null points as well.
