FreqDiv Mod - LPF 'Q' Selection Switch

Post by Muff Wiggler » Sun Aug 19, 2007 12:45 am

The Frequency Divider has a DIP package on the PCB with three settings for the onboard LPF, off, on, and on (steeper). I like to replace this DIP package with a panel-mounted 3-way switch

carefully clip the four leads from the DIP package to remove it, and solder the contact to a 3-way switch.

You can see the switch I made for the panel in this pic (sorry it's so blurry)

The manual says there's four possible levels of filtering (including none). It appears to be a binary setup where closing one contact has more effect than closing the other and there are four possible on/off combinations.

So what did you end up with on your switch?

Blacet:
As the PCB legend implies, placing the #1 switch actuator in the up position results in the least filtering, followed by #2 in the up position, and both #1 and 2 in the up position. If both #1 and 2 are down, there is no filtering.
Thanks

I'd like to know as well.

I'm thinking about a expander panel for the 12 outs plus to on/off switches to choose btn all four possible filtering levels.

I'm gonna bump again, for the same reasons as previously stated: I'll be making this panel soon and would like to know if I need two switches or if the way muff has it rigged is the way to go.

If I understand the schematic correctly, you'd need two two-pole switches (assuming you want all four filter possibilities brought out to the front panel).
