The MP 341 unit is the heart of the MP 300 system and incorporates all the circuitry necessary for handling the signals coming to and from the operator and user positions (operator phonic line and user phonic line).
Four switches inside the MP 341 unit, with corresponding LEDs, are used for setting the 4 different operating modes according to the intensity of noise in the operator position and the user position. A switch for each line makes it possible to select the “direct” function in which the line is always activated, or the “switched” mode, in which the line is activated at the moment of speaking. Using the MP 341 control unit, it is also possible to adjust the listening volume of each position independently, as well as the switching threshold for each microphone (factory preset).
