2.4.1 Selection of a suitable input card
Use an MM or MC input card depending on the installed car
-
tridge system. Please refer to the relevant documentation of
your pick-up system, to find out whether your pick-up system
works according to the MM or MC principle.
There are two types of inputs for MC systems: The most com
-
mon RCA connector or the balanced XLR connector found on
some turntables. Both types of input cards are available for
the PH 8.3.
For MM systems, only one input board with an RCA connector
is available.
2.4.2 Setting the terminating impedance/capacity
In order to achieve optimum sound quality, each cartridge
system must be operated with the appropriate terminating
impedance or capacity. This is particularly important for MM
systems, as the terminating capacity generates a high-fre
-
quency resonance that extends the frequency response. If the
capacity is too low, the sound of the pick-up system may lack
brilliance. If the capacity is too high, the resonance shifts too
far down and thus causes strong peaks in the upper frequency
range, resulting in harsh and unpleasant sound reproduction.
We recommend a consultation of the operating instructions
of your cartridge system before adjusting the respective
impedance or capacity on the PH 8.3. In the opraring instruc
-
tions you will usually find the optimum termination impe
-
dance or capacity. Otherwise you may use a general rule: For
MM systems approx. 200 pF capacity, for MC systems 100
Ohm terminating impedance.
