ADC PATCHBAY PDF

According to ADC , if you run your digital signal though your analog patchbay, you just used of your three-hundred feet. However, you will need to leave around four patchbay channels unused between the digital signals and the analog signals to prevent cross-talk from the digital signals that would well However, if you use a large format console with one-button that turns on the phantom power for all channels you will need to strap the grounds together on the patchbay channels you want to phantom-power. When patching microphones through a patchbay that are being supplied phantom power from a mixing board, patching a mic can damage the console or mic if the grounds are not strapped on the Patchbay! As the patch cable plug is inserted into the Patchbay, the tip of the plug will momentarily connect with the ring contact in the socket, while the ring of the plug touches the sleeve contact.

But really, once you know the fundamental rules and conventions the process is as easy as running cables from one piece of gear to the next. Take into account that most of us end up unplugging three cables by accident for every one we successfully add and you can understand why a patchbay is a non-negotiable piece of equipment.

Patchbays are becoming increasingly important due to the increased popularity of structured wiring, where commercial buildings and homes are built with cabling within the walls and flooring. There is no rewiring in these cases so even the casual user is beginning to be confronted with the issue of using a patch panel. Since collaboration and communication are critical for efficiently recording high-quality music and audio while the creative juices are flowing, nothing is more important than unraveling this mystery and putting it back together in our heads in the same way others have.

The reason is that, before we review any specific models, we give a summarized run down of everything you need to know about these miracle machines, including how to use one. In the same way, it brings you into alignment with other professionals and also keeps you organized. Rule 1 - Top Jacks are for Outputs Always envision the audio signal going into the top back jack and coming out of the top front jack.

In most cases keep it simple for now , the signal comes out of the keyboard or microphone, goes into the top back, and comes out of the top front.

The outputs are top only, back-to-front. Rule 2 - Bottom Jacks are for Inputs So now you have your signal coming out of the top row on the front of your panel. You plug in a patch cable and route it to the bottom row, which is the exact opposite of the top row. It is only for inputs on your gear. The signal flows into the cable, into a bottom front jack, and out of the bottom back jack and into an input in another piece of gear.

The inputs are bottom only, front-to-back. Rule 3 - Connections Only Occur Top-to-Bottom Since outputs are on top and inputs are on bottom, you will never need to or want to patch a cable from a top jack to another top jack.

The same goes for bottom to bottom connections. Patch cables only ever connect a top jack to a bottom jack. These three rules set the stage for making a patchbay useful. The above rules and the tips below will make sure you never are stuck wondering what goes where.

Label Your Jacks: Before all others, this is the most important. Some bays have dry-erase strips you can write on across the front. If not, you can write on the top part of sticky notes and stick them on there. My favorite method is to create a software spreadsheet I can easily re-label. I keep mine printed out in a desk drawer, ready to be referred to at any time.

If you do purchase more than one, designate one as your main patchbay and then have a secondary and tertiary one. This is why we label the jacks! Group by how often you use them, not by type.

Use Short, Color-Coded Patch Cables: The next best thing you can do for organization is to use short, color-coded patch cables. These tend to come in the seven colors of the rainbow, plus white, black, and gray. Colors, on the other hand, are a piece of cake. Hot Wires 1. Once it makes sense for you, it actually reduces the chaos and makes your bay faster to use. There are three ways the jacks are wired together that represent the three main modes of usage.

Some patchbays let you change modes with a switch. Some require you to physically manipulate the jacks. But if you learn to use the other two modes you can really dial in the magic to save you effort and cabling time. The cable interrupts that signal path and intercepts it, sending it through the cable only. This lets you split the signal to send to two inputs.

The splitting will be interrupted if a cable is patched into the front input, though. Thru Mode: The top output jacks only sends the signal to each other, back-to-front. Unless you plug in a cable to send the signal to an input, the signal hits a dead-end. For the most part, Normal Mode and Half-Normal mode will take care of all of your needs. We can then pass back out of the box if we like. Half-Normal is preferred because you can use it like a send to an auxiliary bus on a mixer.

So why is Normal and Half-Normal even a thing? Why are they useful? That can be explained by walking through an example set-up, which we have below. If you can wrap your head around 12 points, you can deal with as many as you want. The key is to be able to trace the signal out and in, out and in, through the jacks and your gear.

Patchbays 101 — Layout, Signal Flow, Normalling & More

If you look at large recording consoles, they all have a lot of patch bays. The more you understand signal flow, the more creative you can when recording and mixing insofar as how you can shape the sound based on where in the signal path you process or access the signal. This means that the output of a signal is literally over the input on the patch bay set up and wiring. So why not just plug the tie lines straight into you console? Because you will most likely want to use an outboard mic pre, or cross patch your mic inputs. Another phrase to know: normalled or full-normalled vs. Normalled sends the signals plugged into the back from the input to the output UNLESS a cable is plugged into either of the two jacks in or out.
