The module PHONO can be optimally adjusted to the used pickup of the turntable.
The value can be taken from the operating instructions manual of the pickup. The
available adjustment values are listed in Tables [A] and [B].
Table [A] shows the values for a capacitive adjustment, as is required for MM
cartridges. Table [B] shows the values for impedance matching, as is required for MC
cartridges.
MM-Cartridges:
The switches S1 and
necessary for MM and are switched off.

The input capacitance without connected capacity of the module PHONO is 60 -
100pF. Each capacitor that is connected must be added to the input capacitance.
The interconnection cable capacitance and the capacitance of the arm tube of the
turntable have to be added, too. In this way, often more than 200pF - 300pF capacity
is added without any additional capacitors.
Should be noted, however, that deviations from the recommended cartridge
manufacturer adaptive capacity, on the order 20-30% are acceptable, as in the
production of pickups often similar tolerances occur.
MC-Cartridges: The switches
remain in the neutral position. Switches
connected MC system. The value can be taken from the operating instructions
manual of the pickup. Table [B] shows all the possible values for this module and
associated switch positions.
It is also possible to set the switches like you want, because it may happen that
different input impedance sounds better than the proposed values. Consequently,
quite a few pick-up manufacturers also give a very wide range of adjustment for your
pickup to (eg 200 Ohm to 47 KOhm). So try out different settings and set the value
that comes closest to your ideal sound. Nothing can go wrong. Please set the volume
low every time you do a switching process between the Switches
