SergeModular

Those of you; like myself, who have been "under the hood" of a Serge
Modular know that most of the circuit boards have names such as Quad
Pan 104A or NTO/CON 107A. Does anyone here know which module the
Board "Hex Filter" is from? An accompanying schematic would also of
use. I have a PCB layout of the board yet have never come across one
in all the Serge's I've worked on. I'm doing my best to have a
COMPLETE understading of ALL the modules Serge made and this board
has created a mystery.

Any help would be greatly appreciated.....Sincerely Dean.

P.S. Dare I mention this... but I'll be a specific as possible so at
to not offend or confuse anyone !!! I too have some CLONE SERGE RACK
EARS I'd gladly sell to anyone (worldwide). Indeed they are CLONES
made from a 1980's model Serge. Being almost 50% thicker than a true
Serge rack ear (.07 inches rather than .053 inches) they can by no
means be called "flimsy" and are pre drilled and ready to mounted
onto a Serge box. Don't have a box? I also have a few rack boxes
SIMILAR to the SERGE rack boxes but also improved upon. Threaded
inserts allow installation/removal of the rack ears without having to
remove the panel from the box to hold the internal nuts. The panels
mount to the box with threaded inserts ( not the little black clips
that fall off and get lost). Finally the boxes are made of a heavier
gauge of aluminium making them "less flimsy". Anyone interested
should E-Mail me directly. No point in cloggin up the user group
bandwidth. Enough people already manage to do that..... unneccesarily.

Cheers....Dean Batute, phix_it@...

A Hex Filter prevents voodoo from entering the system.

Seriously though ... I thought maybe the resonant eq, but that has 10
filters.

That's a stumper.

My best guess is that the six filters represent the "Dome Filter"
or "Constant Phase Shift" often used in frequency shifters. Having
never had a Serge Frequency Shifter in my hands I can't confirm this.
Hopefully someone out there knows ????? Perhaps someone with a
frequency shifter can take a look when they have a moment. :)

Thanks and more thanks.........Dean

Do you have any indication of the age of this board? I have seen a
picture of an old system with a "filter bank" module, which may have
been a proper module or may have been a few standard filters behind a
custom panel.

Is there a pad "Y"? That's usually a +6v supply, which would suggest
an older system (1976 or earlier).

What was the PAN 104A used in? The quad mixer?

To the best of my knowledge the +6V supply was used only in modules
that had trigger signals (either inputs or outputs - Red Banana
Jacks) so the lack of it doesn't neccesarily exclude this module from
being the older series.

As to the Pan 104A It's the Quad Panner board used in...you guessed
it... the Quad Channel Output Mixer.

Thanks for the thoughts though....Dean.
