Hi guys, hi ladies (if there are any)

I have 3x PCB board over, so I would liek to sells these here. A board is 10€ plus shipping and I only have 3 of them.
If interested I also have 3 SIP boards which would be a perfect addition to this. Also ea. 10€ plus shipping.
These are not intend for passive summing, you will need an additional amp like V275, V475, V975 .... If you own to differnent amps it is possible to decide to which amp the input is going (only stereo). :)
Here is the eagle, really foto in 7days.

Tomorrow the boarde will arrive:) I will post real pictures.

Of course these connect to Sub-D 25. Pan should be done before:)
 
summing for sub-d input, and relais based output switch. if combined with the sip board pre and post switch resistors are possible. so you can have a good offness and use different resistors to use different summing amps :>| grounding on both layers.
