  • Page 2 1. Gate - Threshold (Thresh) Controls the amount of input signal level neces- LMR1S LMR1S sary to turn the module’s signal output on and mute lower priority modules. Clockwise rotation increases the necessary input signal level required to produce audio output and mute lower priori- ty modules.

    Jumper Selections PRIORITY LEVELS G ATING HIGHEST LOWEST ENABLED Priority Level This module can respond to 4 dif- DISABLED ferent levels of priority. Priority 1 is the highest priority. It mutes BUS ASSIGNMENT PRIORITIES modules with lower priorities and BOTH is never muted.

  • Page 4: Module Installation

    Module Installation Turn off all power to the unit. Make all necessary jumper selections. Position module in front of any desired module bay opening, making sure that the module is right-side up. Slide module onto card guide rails. Make sure that both the top and bottom guides are engaged.
  • Page 5 Input level can be controlled by an external DC voltage source, which must be able to supply up to 1mA of current to the LMR1S. The attenuation level is linear with voltage. 4.5V or greater = 0 dB of attenuation (full volume) and 0V > 80 dB of attenuation. Distance from the source should be kept to 200 feet or less.

  • Page 6: Remote Control

    TO WIPER TERMINAL SHIELD Note: If no connections are made to the remote control, the LMR1S module defaults to 0 dB of attenuation. Two-Conductor Shielded Remote Connections This configuration is recommended when wire runs up to 2,000 feet are necessary. Use two- conductor shielded wire for this connection.
