The newest Soundtools product is nearly done. The “WallCat” allows 4 balanced XLR lines to mount in an AC wall box. Each WallCat has a RJ45 in and thru. Initially there will be a four mallet or four female XLR version. A 2 male and 2 female version will be available next year. This means you can string inexpensive sheilded cat5/6/7 cable through the building and either use it for high quality audio.
