I use this multicore for "bringing" monitor signals from our headphone amplifier system to the middle of our rehearsal room. After that each band member connects his own XLR cable and his Behringer P2 stick. It is great because we can use only "one" cable and we don`t need to spread five or six different cables throughtout the room. It really helps with rehearsal room cable management!
We use it for around two months now and we didn`t notice any problems with sound, sound loss, crackling or anything like that yet.
The only thing I would change are the connectors (semi plastic) which I would replace with metal ones. But for this price it is really well made and useful product!
Would recommend it!
