Moerch tonearms:

In spite of the slender appearance, the Moerch tonearms have an amazing mechanical strength and stability. They are the result of the best precision mechanics, the finest craftsmanship, and realize technical and tonal claims without compromise.

What has been archived with the Moerch tonearms enables the cartridge to accomplish its task with extraordinary motional ease while maintaining a very high degree of stability.

The proof of their superiority lies in the listening! The Moerch arm have received high acclaim from both critics and skeptics, simply because their sonic superiority can be easily demonstrated.

Moerch DP 6 tone arm

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 7.5 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")
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:	DP-6 Ultra pure silver cores with Teflon. UP-4 High grade copper, or silver as in the DP-6.
Capacitance per channel:	28pF for both models.
Tonearm Cable:	Several insulated cores and gold plated phono plugs.
Capacitance per channel:	100pF. 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 by special order BLACK.
UP-4 finish:	CHROME.
