In a previous article on Patchbays and the author’s own dilemma at having to switch different components in an audio system using XLR and TRS connectors, it made sense to investigate real world examples of what other enthusiasts are doing to complete their kit. Continue reading “Multiplexers (and demultiplexers)”
Note: This is a preliminary article and will cover the construction of a basic Arduino controlled patch bay/audio signal router. Users should be aware that manufacturing a patchbay as a DIY project can and will will be very expensive. The Samson S-Patch Plus retails for between R2000 and R2500.00 in South Africa. A parts B.o.M places this project at about R5 000.00. However, careful consideration of B.o.M (input types) and digital control will be infinitely cheaper than an electronic audio signal router off the shelf.
The Samson S-Patch Plus is remarkable in that it tidies up your flow, gets rid of unsightly cables, is quick and affordable. If you are like me you prefer to purchase pro series audio because it’s modular and often cheaper than commercial consumer integrated audio. So you can throw away the parts you don’t like and only add that which you deem necessary and very importantly, have some control from the PC or laptop.
This comes at a price of course, spaghetti! And if you are like the mechanic whose car never runs properly this spills down to never being able to find that missing plug or socket. To be honest, pro audio can be a nightmare.
