Not to worry my friend! In professional use, XLR cables are often over 100 fwt long. Think of auditoriums where the mikes are on the stage and the sound booth is in the back of the hall. Those tiny mike voltages make it good shape to the mixers far away. Use the Belden mike cable or its Chinese clone. Enjoy the music.
Really Long XLR
Looking to move my front end gear to the side wall in a new listening room. If I don't want cables running across the floor in front in my speakers etc., then I'm going to need a set of XLR interconnects in the 40 - 45 foot range. Wondering what other members have done and what cables have been selected for a very long run. Obviously the companies asking $$$$ for a one meter set are not in the running. All suggestions are welcome. Not afraid to build my own if anyone has had great experience with bulk XLR cable. Thanks.
