Product Overview

Radio Design Labs' STM-LDA3 is designed for use in quality commercial sound, broadcast and recording applications. The 1.2 kohm balanced input accepts a wide variety of microphone input levels without loading professional low-impedance microphones. A multi-turn gain trimmer allows precise output level adjustment. The output signal is available on three separate balanced line level outputs. Each output may be connected balanced or unbalanced.

RDL's exclusive low-noise discrete preamplifier circuitry produces studio-quality low-noise performance in an economical preamplifier. Dynamic or condenser microphones may be used with the STM-LDA3. Standard 24V phantom is supplied to the input when the supply voltage is connected to the PHM terminal. Optimum operating level is set using RDL's unique dual-LED VU meter, located adjacent to the terminal block. A green LED illuminates at 15 dB below a +4 dBu output. The intensity of the green LED progresses from minimum to full intensity at +4 dBu. The adjacent red LED illuminates when the operating level exceeds +4. This makes the STM-LDA3 easy to set up without any external test equipment, and operating levels may be monitored at the module.
