Balanced Audio VK-P6SE Phonostage - Manual (Page 10)

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.
Gain Switch
By moving the switch S2 from High to Low position, the amplifier’s gain is
reduced by about 6dB. While the High gain position provides the most
universal setting, it may be desired to reduce the overall system gain when
using some high output phono cartridges.
Gain Potentiometers
Balance Adjustment: The R130 and R230 controls can be used to
compensate for system balance shift, such as when using cartridges exhibiting
output voltage differences between the left and right channels.
