Amek M2500 EQ questions New
« on: December 03, 2008, 06:57:50 AM »
Hi everybody,
I'm building an Amek 2500 eq.
I have some simple questions for you...

1 Can I put some DPDT switches to bypass every single eq section as showed in my modified schematic?
  Do you think there could be possible strange effects?

2 Can I use 20K lin pots instead 22K lin for gains? If I use 20K pots I have to replace the 22K resistor to 20K?

3 What is the use of the switch with a 1M resistor in the LF section?

4 Did you saw the original Amek M2500? the HF and MF1 have the same frequencies range...same as MF2 and LF.
  How is it possible? there are different frequencies capacitors in the sections.

Thanks!
