Settings on phono stage


 Here is the instructions:
  

 

Cartridge loading is achieved via internal dip-switches. Factory setting is 100 ohm, zero capacitance.

 

Two 6-row dip switch banks are located on the board. Loading is as follows:

 

  • Dip Switch 1 up = 100 ohm; Dip Switch 2 up = 100 ohm.
  • Dip Switch 1 & 2 up = 50 ohm.
  • Dip Switch 3 up = 1K; Dip Switch 4 up = 1K.
  • Dip Switch 3 & 4 up = 500 ohm.
  • Dip Switch 5 up = 47K; Dip Switch 6 up = 100pf.
  My cartridge is Clearaudio Concept MM.  Specs say:  Loading impedance :  47kw   Loading capacity : 100pf.. I put dipswitch 5 up,should 6 be up ? It sounds good,but I have some hum and my woofers seem to be fluttering quite a bit also. If anyone could help  it would be much appreciated. I did email manuf. but havent heard back yet.

Switch 6 is just giving you added capacitance which your cartridge may or may not need to sound it's best.
Just listen but I doubt you'll hear much difference in which case leave it switched down.
