Router - NLC build notes

Some build notes for the Nonlinearcircuits router.
I'm hoping this will function something like the Serge bi-directional router, but with 4 outs rather than two.
A router can also be found in the NLC Chopper.

The new NLC Router is a voltage controlled switch that can deliver 1 into 4, 4 into 4 and 4 into 1 at the same time, 2x 2 into 2 and, with a simple mod to the PCB, 2x 1 into 2 

This looks like a easy build.
ICs on first.
The module uses a DG412 which is a CMOS analog switch.

Control inputs are pins 1,8,9,16 (in)
D1–D4 : Analog Switch Drain Terminal
 S1–S4 : Analog Switch Source Terminal

Passives, resistors, diodes, caps
The thru hole stuff.

Jacks & pots.

Input 1 is internally connected to the switches on jacks 2, 3 & 4.
CV 1&2 is internally connected to the switch on the CV 3&4 jack.
The signals to the OUT ALL jack are summed together

The Router pots can be used as switches, 0 is off and 10 is on. At these settings the switches will ignore incoming CV or gate signals. For the switching to be controlled by CV or gates, set the pots to an appropriate turn-on point.
