This section describes the setting of internal configuration switches that are located inside the 
VK-P10SE phono preamplifier.  In order to access these switches, do the following: 
 
1.  Turn the VK-P10SE OFF and disconnect the power cord from the power line receptacle. 
 
2.  Remove the top cover, using the supplied Torx T-10 wrench. 
 
 
Figure 1 
depicts the locations of the VK-P10SE internal configuration switches.  These 
include: 
 
 

1.  Left and right channel cartridge loading switches S101 and S201 

 
 

2.  Direct/Step-Up input mode switches S102 and S202 

 
 

3.  Gain switch S2 

 
The following section describes the operation of these controls. 
 
 

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-P10SE PC board.  This is accomplished by using the two DIP switches, S101 and S201
that 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-
P10SE 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 

 
 

 

 

100 Ohm 

 

 

 

1K 

 

 

 

10K 

 

 

 

User-Defined 

 
Any parallel combination of these values is also allowable.
