It splits a single microphone to several destinations, such as a mixer, recorder and assistive listening system, in commercial sound, broadcast and recording applications.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/stm-lda3.jpg\" alt=\"RDL STM-LDA3 front panel\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe 1.2 kohm balanced input accepts a wide range of mic levels without loading low-impedance microphones, and a 25-turn trimmer sets gain from 40 to 60 dB. Dynamic or condenser microphones may be used, with standard 24 V phantom supplied when the supply voltage is connected to the PHM terminal. RDL's dual-LED VU meter beside the terminal block shows green from 15 dB below +4 dBu and red above +4 dBu, so the module can be set up without test equipment. Three +4 dBu, 150 ohm balanced outputs can each be wired balanced or unbalanced.
