The last batch of 50 DB25 boards has nearly gone so I have ordered yet another batch. I am selling lots of these but not hearing about many completed projects. Where are they all going???

I'm racking up 8 stereo Midas XL3 modules. I was thinking of using DB25 for the patchbay because of space constraints. I will also probably need 2 summing amps. One for the 16 aux outs and another one for a stereo master output. My idea was to etch boards for right angled DB25s to make connections easier and avoid having to solder the cables directly onto the DB25 connector (been there before).
My questions are:
-Can I use your PCBs without a summing amp (just as a connection platform for the Ins and Outs)
-If I use your PCBs to create a summing amp for the aux master sends, how do I know what resistors etc to use? Would you have a schematic for that?
-Finally, are your PCBs' print compatible with any right angled DB25 or should I buy a specific brand/model? If so do you have a Mouser part number by any chance?
You should treat J6 just like pin 1 on an XLR - it should be connected directly to the chassis (at the connector if possible). Whether you actually need to do this depends on the DB25 connector you buy. On some types, the fixings that hold the connector to the board are connected via the connector body to the shell which is then screwed to the chassis. The more economical connectors have plastic bodies so this connection does not exist - instead you use J6 to make the connection from the screens to the chassis.Pascau said:On the board, J6 screen is already connected to the ground pins on the db25 channels correct? And I would just wire J6 to my ground without having to wire individual grounds on the db25 or anything?
Also, what watt rating should the resistors I use be?
Thanks!

that's a great approach! !
Which leads me to an other short question.
Do I have to short "+" and "-" if the input isn't connected, to keep maintain the bus impedance constant?
Cheers!

how are you? How are you fixed on these boards? I could use 5 of them, let me know
thanx
