Nº26, internal adjustments
If you wish to vary the input capacitance of the phono option to obtain the optimal value for a particular cartridge, a capacitor may also be inserted into the optional load terminals (see "Terminating the optional load" and "Making the internal adjustments").
Because the inherent input capacitance (all switches off) is in parallel with the optional load terminals, use the following formula to calculate the actual capacitor needed.
C = CR - CT - CP
C = The capacitor value
CR = Recommended capacitance value CT = Tonearm capacitance including leads CP = Preamplifier inherent shunt capacitance
Note: We recommend
The Nº26's optional balanced input module allows you to adjust the input gain. If you wish to adjust the balanced input gain, see "Making the internal adjustments;" refer to the table below for the proper switch positions for each gain setting.
