LV30 speaking station

in control desks and control cabinets for signalling or communication. The connections of the electronics module are routed to a terminal strip which enables the further wiring. Connection of a microphone and the related talk key to the terminals of the electronics module LV30 FTS is possible. The microphone is activated by pressing the talk key. The downstream connected microphone amplifier boosts the signals recorded via the microphone to such an extent that afterwards they are input into the WL (LF)-wire pair at a nominal level of -6dB. A potentiometer installed right beside the connecting terminals allows varying the microphone sensitivity. In assupplied condition, this potentiometer is set to the centre position. |
