While playing a record, the tonearm must be able to move bothhorizontally and vertically – horizontally as the cartridge movestowards the center of the record, and vertically to allow forimperfections (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 frequencymotion of the stylus will be transferred to the cartridge itself, whilethe cantilever of the cartridge almost does not move, and thus only aweak signal is induced.

To have excellent audio reproduction at these low frequencies, thehorizontal movement of the tonearm must be restricted – but to ensureperfect tracking this must be achieved without a similar restriction ofthe vertical movement. This “anisotropic” principle – differentcharacteristics for different directions of movement – is the essence ofthe MØRCH DP-8.

The DP-8 has a flywheel shaped central body and two weights on the sidesto stabilize the movement of the tonearm horizontally. Thus, as thecartridge moves towards the center of the record, it can only follow theaverage location of the groove. It cannot follow the modulation, whichis all transferred to the cantilever. This means that all the recordedbass, even the very low end of the range, is reproduced with fullamplitude and dynamics.

DP-8 with 9” PRECISION armtube. It is the two weights on each side ofthe heavy central body of the tonearm that provides for the majority ofthe effective mass (Inertial moment) for the horizontal mode of motion.The center of gravity of these weights are pointing backwards – eitherupwards or downwards, so that they contribute to the counterweighs atthe same time as they provide for moving the center of gravity of themoveable part of the tonearm up or down.

Here the DP-8 is shown with a 12” armtube.

Model DP-8 has a unique combination of bearings: For the horizontal modeof motion a silicone damped high precision ball-bearing assemblyincreases the stability provided by the large housing and sideweights.For the vertical mode of motion two precision sapphire bearings areincorporated.
The vertical motion also may be damped if desired, by injecting siliconefluid into a well. Vertical damping is rarely needed for this model. Itis independent of the damping of the horizontal mode of motion, andfurther 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 tonearmfor any cartridge is maintained. Thus warps will not influence thetracking force, and there will be no vertical deflection of thecantilever.

In model DP-8 the azimuth adjustment for perfect channel separation isaccomplished at the pivot of one of the sapphire bearings.
