While selecting the input capacitance please keep in mind the capacitance
of the connection cable from the analog drive to the SAM 20 SE (approx.
100 pF per meter of length). Exceeding capacitances most probably lead to
presence boost and high frequency attenuation.
As described above, the input capacitance is extraneous for MC pickup
systems. Some systems call for a higher input resistance (2.2 k
W
), others
need a much lower setting (100
W
) for optimum performance. Please fol-
low the recommendations of the manufacturer of the pickup.
10.7 Factory defaults
The SAM 20 SE is set to the following factory default configuration:
Gain
58 dB
Input resistance
470
W
Input capacitance
110 pF
This configuration is suitable for most MC pickup systems.
Tip
·
While you order the SAM 20 SE let your dealer know which pick-up
system you are using. Thus, the SAM 20 SE can be configured to your
required settings in the factory.
