Attaching The Phono Lead - Oracle Audio Delphi MkVI Gen-2 Owner's Manual

How the MVSS control works:
When in the full "UP" position ( completely against the sub-chassis ) the plungers barely come in contact with the
silicone fluid in the reservoirs. If you play your Delphi without the MVSS plungers inserted in the silicone
reservoirs there will be no or very limited control of micro vibrations. Each full turn of the plunger will result in a
1,27mm ( 0,050" ) vertical displacement. Since we are dealing with micro vibrations it is extremely important to
lock the plunger in position with the wheel lock nut. Leaving the plungers in an unlocked position will defeat
most of the purpose of the MVSS. At the factory the best results were achieved with a calibration between 1 1/2
and 2 turns down. This represents a plunger penetration from 1.90mm (0,075") to 2.54mm (0,100") into the
silicone fluid eservoirs. In fact, it is a little more than this because the surface of the plunger that is immerged in
the silicone forces the fluid up in the reservoirs. The MVSS fine tuning is guided by two factors, the room ambient
temperature and your personal musical preferences. The MVSS has been designed so it can overdamp micro
vibrations so it is extremely important to understand this reality! If the plungers are calibrated too far down ( 4
turns down for exemple ) in the silicone reservoirs some mechanical energy will start bypassing the suspension
system. The system has been purposely designed like this to make sure the optimal calibration of the MVSS
could be achieved under all conditions.

ATTACHING THE PHONO LEAD


Connect the phono lead to the base of your tone arm.

Retrieve the strain relief device from the packaging.

Secure the lead to the strain relief device form above or below the plinth.

Create a loop from the base of the tone arm to the strain relief device to prevent any interference of the
lead with the suspension system. Make sure the looped wire does not come in contact with the table
below.
Note :
In some applications, the phono lead might be too stiff. It is recommended to split the moulded wire
from the plug to the strain relief. If the loop is too long, the lead could come in contact with the table below. If it is
too short, it will prevent the suspension system from moving freely. In both cases, this would be detrimental to
the sound.
