The LMR1S module has a LINE/MIC level input module with remote volume control capability. Input level control are by remote potentiometer or by direct voltage input (0 – 4.5V DC). Input via front-mounted screw terminals. The LMR1S 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 18 dB to 60 dB in MIC position, or from -2 dB to 40 dB in LINE position. It has the ability to mute lower priority modules and be muted by higher priority modules. The module is also able to assume any of four priority levels. The module has an internal gating circuit with controls for threshold and duration. It has a built-in limiter to control the maximum output level of the module. The module also has an LED to indicate limiter activity. The module has bass and treble controls with cut and boost of 10 dB at 100 Hz and 10 kHz, respectively. The module’s output is assignable to either or both of two mixing buses.
