The "QG" (XLR) Patchbay features a 19" rack unit loaded with E Series "QG" connectors. These XLR’s have the same panel cut-out, male or female, silver-plated pins or contacts, and a black finish. All connectors have solder cup terminals for easy soldering and the inserts are removable from the back, allowing for easy changes. The one rack unit height version comes with 16 male, or 16 female, or 8 male and 8 female connectors. The two rack unit version comes with 16 male and 16 female connectors. All versions have a rugged cable tie bar, which takes the weight of the cabling away from the solder connections.
