STEP 1

Step 4 WIRING UP

The accompanying diagram shows the wiring up of the device. As mentioned previously it's a good idea to wire up the 12way rotary switches before mounting them in the case. The resistors are daisy chained between the switch contacts.Having wired these up mount in the casein the case as shown. The whole device can now be wired up. OFC(Oxygen free copper) screened lead was used in the prototype. Straightforward OFC hookup wire (16/02) was used between S1 and the input sockets SK1/2/3.When finished the project should look like the photo.
