MAD SCIENCE LAB SSM2 Rev 3 Boards

Main SSM2 page

Here is a picture of the SSM2 board without the dual LFO's under test. This one built 2/2/2007

 

 

Below is a close up of first board without the LFO section

This board has the following connections on Molex .156 headers. The 2 filters are completely separate.

-- Filter 1 -audio in and out

-- Filter 2 -audio in and out

-- Filter 1 -4 frequency control voltage inputs (-15 to +15 volts)

-- Filter 1 -3 resonance control voltages (0 to -15 volts)

-- Filter 2 -4 frequency control voltage inputs (-15 to +15 volts)

-- Filter 2 -3 resonance control voltages (0 to -15 volts)

-- Power in (+15 ,-15 volts and ground)

 

Above the empty socket waiting for a SSM 2040 chip.

The four clear capacitors help form the four poles of the filter.

Not as nice a circuit board and .100 small molex headers

 

 

My Sr thesis was on analog design of Filters and Oscillators. See a part of it here
