Kopul XLR4 Reviews

A cleaner way to run multiple audio channels (or DMX)

By Jim
Rated 5 out of 5
Date: 2026-08-21

I really like this kit because it makes running multiple audio channels a lot easier. I am using it to send multiple channels of audio over a single etherCON Cat cable, which is much cleaner than having to deal with a bundle of individual XLR cables. Once everything is connected, it keeps the setup much more manageable and is especially useful when I need to make longer runs. The units themselves feel very well made. The steel housings are solid and are great to mount permanently. But the build quality also gives me confidence that they can handle being used around production equipment and getting packed up and moved from one location to another. The locking EtherCON connections are another nice touch since I do not have to worry about a network cable accidentally getting pulled out during a shoot. I also like that the units are passive, so there is no power supply to deal with. For audio production, live events, or even DMX lighting, this is a really practical way to simplify a complicated cable run. [I have received this product in exchange for my honest review.]

Be sure your grounded

if your running these with bulk cat be sure to have shielded cable for ground and etherCON ends, otherwise your channels will be unbalanced. In my application I hard mounted a set to connect two zones in a bar. However I ran unshielded/unended cat5 and had to run a second cat5 just for ground, I just unscrewed one of the etherCON passthrough screws, put the single wire in and re-screwed the connector down. it worked.

Can you "daisy chain" these extenders by connecting two male or two female extenders via Cat 5?
Asked by: David
Each Kopul 4-Channel XLR Network Cable Extender only has a single RJ45 port, so they cannot be daisy chained.

Sorry, my question was about the maximum length of the network cable that we can use for transmitting audio signal. Thanks!

Fixing the XLR gender being wrong with adapters, ...

Fixing the XLR gender being wrong with adapters, will these extenders pass audio in both directions on the Ethernet cable?
Asked by: Steve
XLR is not de-facto a directional medium, which is to say that it's really just a set of three pins with copper wire in between. Audio can only flow one way from an XLR connector to another, but it doesn't actually matter which direction that is. So, if for some reason you have audio passing from male jack 1 of the Kopul 4-Channel XLR Network Cable Extender Kit to female jack 1, that will work fine. You just can't have audio flowing both ways at the same time between two connectors.
