Moerch Tonearms
Moerch DP-6
Moerch UP-4
The surfaces of the
armtubes are inspected.
The armtubes have now
been plated with 24 carat gold.
The thickness of the gold is
meassured with X-ray equiptment.

Technical specifications: Moerch DP-6/UP-4
| Construction: | Radial arm with interchangeable arm tubes. |
| Bearing principle: | DP-6 Dual
bearing UP-4 Unipivot. |
|
Effective mass of complete tonearm with arm tube: Light (green): Medium (red): Heavy (yellow): Extra heavy (blue): |
All arm tubes
can be used with both models. 4 g 6 g 8 g 14 g |
| Fundamental resonance (depending on arm tube): | 8 - 16 Hz |
| Tracking force (when using calibrated scale): | 0 - 3 g |
| 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: | 212 mm (8 5/16") or 294.1 mm (11 9/16") |
| Diameter of hole for mounting arm base: | 20 mm (13/16") |
| Rear overhang from pivot: | 70 mm (2 3/4") |
| Effective length: | 230 mm (9 1/16") |
| 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 both models. |
| Tonearm Cord: | Balanced.
Extremely purified copper strands that are heavily silver coated.
Halogen free insulation. Moerch tonearm connector with Cardas DIN inlet and RCA connectors. Capacitance per channel: 100pF. |
| Terminals: | All terminals throughout the arm are gold plated. |
| Bearing concept of model DP-6: | One internally damped, precision ball-bearing assembly for the horizontal plane of motion. Two pivoted sapphire bearings for the vertical mode of motion which can be damped also, if desired, and then adjusted to different levels of damping. |
| Bearing concept of model UP-4: | Hardened steel pivot resting on a concave sapphire, and damped for all motions with silicone fluid. |
| DP-6 finish: | 24 carat GOLD, CHROME, or at special order BLACK. |
| UP-4 finish: | CHROME or at special order GOLD. |
