XLR

XLR and DMX cables have a bit of overlap and it can be difficult to keep the two separate. The short answer is that XLR is used for audio while DMX is used for lighting. Both cables use the same kind of connectors and look the same on the outside, there are differences on the inside. There is a little bit of cross-functionality, but XLR and DMX should not be interchanged unless users find themselves in a desperate situation.

Are DMX and XLR Connectors the Same?

Whereas DMX refers to something specific, “XLR” is more of a catch-all term. It can refer to an XLR cable, XLR connector, or even audio cables in general. Oftentimes, microphone cables are referred to as XLR even if they may feature another kind of audio connection as well. DMX cables do use XLR connectors, but their specialized use has given the

“Pinout” is a term describing how an electrical cable is wired. Some cables do not have pinouts because they only contain a single internal wire, like coax cables. But if a cable has multiple pins on the end of the cable, it will have a pinout.

Each type of multi-pin cable has a standard pinout or two, but these layouts are not set in stone. Some machines will require non-standard pinouts; this will require users to use a custom cable.

Pinouts also come into play when using a cable with two different ends. For example, going from DB9 (9 pins) to DB25 (25 pins) will mean the DB25 side has 16 unused, “dead” pins.

If you need to know what pinout a cable needs, ideally there will be a spec sheet h

Audio and video cables go hand-in-hand, often being paired together. Some cables can even transmit audio and video on just one line. Over time a lot of new audio and video cables have been introduced, so the cable you need will often depend on the age of the equipment you are using. Most TVs, computers, and other devices can use multiple types of audio and video connections, so it is good to be able to identify them and know your options.
