The efficient Bogen LMM1S Input Module with Screw Terminal Connector is an actively balanced plug-in module designed to pre-amplify microphone inputs to line-level. It is compatible with the Vector mixer/pre-amplifier model VMIX. A mic/line switch sets the input gain range for the intended input device. Jumpers are used to select between 4 levels of priority; the LMM1S can mute lower priority modules and can be muted from higher priority modules plugged into the same VMIX. When using the module with condenser microphones, a jumper can be set for the module to supply 24V phantom power. This input module features bass & treble, gain/trim, and gate threshold & duration controls.
