This versatile Redback® PA mixer features six input channels, each selectable for either balanced microphone or line-level operation, along with two dedicated RCA line-level inputs and a 3.5 mm auxiliary input for portable audio devices. A dedicated UTP input, which is internally mixed with Line Input 2, accepts compatible Redback UTP Solutions products, allowing audio to be transmitted over Cat5/Cat6 cable for extended-distance installations. The mixer provides two levels of VOX priority on Inputs 1–2, with independent VOX sensitivity adjustment for each input. Phantom power is individually selectable for the six XLR microphone inputs. This model also includes a set of mute contacts for connection to a building’s Fire Indicator Board (FIB). When activated by the FIB, these contacts mute the local PA/BGM system, ensuring the building’s emergency evacuation system has priority during an emergency.
