Works perfectly for my application. I am sending L/R outputs from my mixer to L/R inputs to a subwoofer. Then I am using the two return XLR cables to take the high pass outputs of my subwoofer and return those as inputs into my mixer to send to my amplifier to L/R main speakers. It was much better to stretch one multihead XLR cable rather than 4 separate cables.
We bought both the 20' and 30' lengths of this product. We use them with our live band to connect a mixer, located on-stage, to the musicians on the center and far side of the stage. One snake sends two mic signals and returns two monitor signals. The other snake sends two keyboard signals and returns one FOH signal and one monitor signal. These two cables now replace the previous eight cables.
PROS: Although they are not Neutrik connectors, they are decent quality and have a firm connection to other connectors.
CONS: The products we received had four male connectors on one end and four females connectors on the other. We contacted Monoprice who then discovered the mix up from their supplier. We decided to keep these cables and swap the ends ourselves. Monoprice's customer service rep was very helpful when dealing with this issue. They refunded us the cost difference of the correct/incorrect cables and gave us a bit of in-store credit for our trouble.
Our band uses about six of them in our PA setup. I've modified some of them to increase the free length, and we've been able to eliminate all our individual XLR cables. The weight of the individual cables is perfect - rigid enough to resist tangling and light enough to be quickly deployed. Now if they only made a 30 ft 8 channel...
PROS: Very good quality and an unbeatable value.
CONS: It would be nice if there were versions with all of the connectors in the same direction. It would save me the trouble of re-terminating.
