Morch DP-8 Tonearm
While playing a record, the tonearm must be able to move both
horizontally and vertically – horizontally as the cartridge moves
towards the center of the record, and vertically to allow for
imperfections (warps and bumps) in the record.
At very low frequencies the modulation in the record is only horizontal. If the tonearm can move too freely horizontally the low frequency motion of the stylus will be transferred to the cartridge itself, while the cantilever of the cartridge almost does not move, and thus only a weak signal is induced.
To have excellent audio reproduction at these low frequencies, the horizontal movement of the tonearm must be restricted – but to ensure perfect tracking this must be achieved without a similar restriction of the vertical movement. This “anisotropic” principle – different characteristics for different directions of movement – is the essence of the MØRCH DP-8.
The DP-8 has a flywheel shaped central body and two weights on the sides to stabilize the movement of the tonearm horizontally. Thus, as the cartridge moves towards the center of the record, it can only follow the average location of the groove. It cannot follow the modulation, which is all transferred to the cantilever. This means that all the recorded bass, even the very low end of the range, is reproduced with full amplitude and dynamics.

DP-8 with 9” PRECISION armtube. It is the two weights on each side
of the heavy central body of the tonearm that provides for the majority
of the effective mass (Inertial moment) for the horizontal mode of
motion. The center of gravity of these weights are pointing backwards –
either upwards or downwards, so that they contribute to the
counterweighs at the same time as they provide for moving the center of
gravity of the moveable part of the tonearm up or down.
Model DP-8 has a unique combination of bearings: For the horizontal mode
of motion a silicone damped high precision ball-bearing assembly
increases the stability provided by the large housing and sideweights.
For the vertical mode of motion two precision sapphire bearings are
incorporated.
The vertical motion also may be damped if desired, by injecting silicone fluid into a well. Vertical damping is rarely needed for this model. It is independent of the damping of the horizontal mode of motion, and further it can be adjusted to all intermediate levels of damping.
Model DP-8 has an integrated device for adjusting the VTA while playing. Markings for "getting back" to a special setting is provided.
The feature with different weights of armtubes to optimize the tonearm for any cartridge is maintained. Thus warps will not influence the tracking force, and there will be no vertical deflection of the cantilever.
In model DP-8 the azimuth adjustment for perfect channel separation is accomplished at the pivot of one of the sapphire bearings.
Supplied in CHROME- or 24 carat GOLD finish.
The armtube plating being made without the use of magnetic materials.

Morch DP-6 Tonearm
Model DP-6 has a unique combination of bearings. A silicone-damped, high
precision ball-bearing assembly is used for the horizontal plane of
motion. Two precision sapphire bearings are incorporated for the
vertical mode of motion, which may be damped also, if desired, by
injecting silicone fluid into a well for vertical damping. The damping
of the horizontal plane of motion is independent of the damping of
vertical mode of motion, and the latter can further be adjusted to all
intermediate levels of damping.
In model DP-6 the azimuth adjustment for perfect channel separation is accomplished at the pivot of one of the sapphire bearings.

Morch UP-4 Tonearm
Model UP-4 incorporates a special concept of the unipivot principle. The
bearing consist of a hardened steel pivot resting in a concave,
polished sapphire. The bearing is damped in all directions with silicone
fluid. The low positioning of the bearing provides for a greater
stability compared to other unipivot arms, since a considerable part of
the moveable mass of the arm is positioned above the pivot point.
With the model UP-4 the azimuth adjustment is made by the way of the counterweights.
Supplied in CHROME- or 24 carat GOLD finish and at speciel orders also in BLACK.
