Cartridge loading switches S101 and S201
Resistance:
The 47K load resistor is permanently connected to the cartridge input. If a different loading
value is desired, it can be obtained by switching in additional resistors, installed on the
VK-P5 PC board. This is accomplished by using the two DIP switches, S101 and S201,
which allow multiple choices for resistive and capacitive cartridge loading. Four positions are
reserved for the choice of resistance and four for capacitance. Out of each group of four, one
position is loaded with female pins and allows the user to install any desired value component
(this position is marked “USER”). Gold-plated solderable pins are supplied with the VK-P5
accessory kit, that should be attached to either resistors or capacitors supplied by the user.
This allows for easy installation and upgrade of user-supplied components.
The following resistors can be added in parallel with the 47K load:
Switch position
Resistor Value
1
100 Ohm
2
1K
3
10K
4
User-Defined
Any parallel combination of the these values is also allowable.
Capacitance:
Various values of capacitors can be connected in parallel to the input via switches S101 and
S201. With these switches in the OFF position, there is no capacitive loading to the cartridge.
The capacitance choices include:
Switch Position
Capacitor Value
5
100pF
6
470pF
7
1000pF
8
User-Defined
Any possible parallel combination of these values is also allowable.
