It has been brought to my attention I have a "wrong"
instruction in the manual. (DON'T PANIC,
KEEP READING).
On the top of page 11, you are told to add "input grounding"
leads on the 3 IN jacks.
Errr....NOPE!
In fact, if you look at the schematic, these connections are *not shown*
(the schematic IS
correct, my instructions are not).
So, unrack, the modules, remove the power cable, and carefully remove these
connections with a
pair of dikes (diagonal cutters for the newbies, stop with the wisecracks
already). If you bought
*assembled* modules, these may be 'missing' already. When present, there is
a silver wire
soldered from the TOP lug to the BEVELED lug. Be careful that clipping the
leads go not cause
them to fly off into the other modules :(
You DO NOT HAVE TO DO THIS if you don't want to. I *am* changing the manual
for future shipments.
Why do this? Because in the '490, the input summer is NOT like all the
other VCFs, and these
added connections to ground (when no signal is patched in) will GREATLY REDUCE
the overall signal
through and out of the filter. Be prepared, the difference is pretty
dramatic :)
Again...this ONLY IS FOR THE '490. LEAVE YOUR OTHER FILTERS ALONE!!
Sorry about that, this is what happens with too much "cut and
paste" going on.
OK, back to soldering..........
