Dynavector DV507MKII Tonearm Instruction Manual
DV507MKII Instruction Manual 1. Introduction Thank you for your purchase of the DV-507MKII tonearm. 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. Temporarily place the tonearm into to this hole.
5. Connection of the arm cable The tonearm cable supplied is designed to the highest specification, with a double-balanced, shielded cable and 4N OFC/6N. 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.
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.
-3. Mounting the headshell to the tonearm. Use the stylus guard to avoid accidental damage. 6-4. Main weight adjustment DV507MKII is essentially two arms on one. The heavy and rigid main arm moves only in a horizontal direction and does not effect the VTF (Vertical Tracking Force) of the cartridge - however there is an adjustable balance weight so that the bearings are evenly loaded to reduce friction and bearing ‘chatter’.
E.g. When the total weight is 20g and you use sub weight A, you should adjust the front end of the main weight to line up with the 20 above the ‘A’ printed on the arm - see picture. 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. Please note the screws of the sub-weight should face toward you. (1) The VTF dial should be adjusted to “0g” point.
6-6. Arm height (VTA) adjustment (1) Adjust the arm height approximately by loosing the height adjustment screw on the side of the arm mount and sliding the whole arm up or down. (2) Tighten the height adjustment screw. (3) Loosen the height adjustment lever by turning anticlockwise. (4) You can then adjust the arm height more precisely by moving the height adjustment lever left and right.
6-8. Arm lift (cueing device) The silicone oil dampened tonearm lift is provided. (1) To lower the stylus onto the record Position the tonearm so that the stylus is over the record groove and lower the arm lift lever carefully. (2) To lift the stylus from the record raise the arm lift lever carefully. 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.
