Hi,
according to :
"Alternate layout
Having had the prototype in my synthesiser for some time now, a
second layout became obvious. Instead of having pots for both the B
channel and the multiplier outputs, I used a 4 pole 2 position switch
to select between the B channel and the multiplier outputs, saving me
a lot of panel space. The x2 output was sacrificed, and the rotary
switch to select the prescale was replaced by an SPDT switch for the
bypass function, and a SPDT center off switch was used to select
between divide by 3, 7 and 5. 7 is hard wired as the default on the
PCB, so no connection is needed to the switch. "
I've organized now a 4 pols 2 position switch, a SPDT on-on and a
SPDT on-off-on.
Can somebody please help me in terms of how to connect it to the
respective pads.
Am i right with my assumptions:
a) rightmost position of the pots to the 4x2 switch
b) from the 4x2 to the respective Pad on the PCB
c) mounting the center position to a pad before the 47K resistor "bank"
What i didn't get:
- Bypass/Prescale switch -> what to connect where
- Prescale DIV -> what to connect where.
Any help would be greatly appreciated.
