| Construction: | Radial arm with interchangeable armtubes. |
| Bearing principle: | DP-6 and DP-8: Dual
bearing UP-4: Unipivot. |
| Effective
mass of complete tonearm with armtube: Light (green): Medium (red): Heavy (blue): |
All armtubes
can be used with all models. 4 g 7.5 g 14 g |
| Fundamental resonance (depending on armtube): | 8 - 14 Hz (for DP-8 N/A for the horizontal mode of motion) |
| Bias compensation: | Watch spring with string - adjustable while playing. |
| Azimuth: | Azimuth is adjustable for correct channel separation. |
| Cueing mechanism: | Piston in U-pipe, damped with silicone fluid. |
| Distance between pivot and center of turnable platter: | 9" tube: 212 mm (8
3/8") 12" tube: 294 mm (11 9/16") |
| Overhang: | 9" tube: 18 mm (11/16") 12" tube: 13.3 mm (1/2") |
| Effective length: | 9" tube: 230 mm (9
1/16") 12" tube: 307.4 mm (12 1/8") |
| Diameter of hole for mounting arm base: | 20 mm (13/16") |
| Rear overhang from pivot: | 70 mm (2 3/4") |
| Offset angle: | 24 degrees. |
| Lateral tracking error: | 0 degrees at 66 mm and 120.9 mm from center of record. |
| Pivot point: | Pivot point is in level with the record surface. |
| Bearing Friction: | Bearing friction less than 0.04 mN in all directions. |
| Balancing: | Four (4) different balancing weights. |
| Internal wiring: | 19 strands of ultra pure silver insulated with Teflon. |
| Capacitance per channel: | 28pF for all models. |
| Tonearm Cord: | Balanced. Extremely purified copper strands
that are heavily silver coated. Halogen free insulation. Moerch tonearm connector with Cardas RCA connectors. Capacitance per channel: 100pF. |
| Terminals: | All terminals throughout the arm are gold plated. |
| Bearing concept of model DP-6 and DP-8: | One
internally damped, precision ball-bearing assembly for
the horizontal mode of motion. Two pivoted sapphire bearings for the vertical mode of motion. |
| Bearing concept of model UP-4: | Hardened steel pivot resting on a concave sapphire, and damped for all motions with silicone fluid. |
