The LMM1S module has a Line/MIC level input module. Input is via front-mounted screw terminals. It also has an internal, 24V DC phantom power supply that is enabled by a PCB jumper. The module has a gain control that will allow gain to be adjusted from 18dB to 60dB in MIC position, or from -2 dB to 40dB in LINE position. It also has the ability to mute lower priority modules and be muted by higher priority modules. The module is able to assume any of four priority levels and has an internal gating circuit with controls for threshold and duration. The module has bass and treble controls with cut and boost of 10dB at 100 Hz and 10 kHz, respectively. The module’s output is also assignable to either or both of two mixing buses.
