The STM-2 is a high quality, miniature wall and surface mount low-noise microphone preamplifier from RDL , designed for use in commercial sound, broadcast and recording. The unit is very flexible with gain adjustment, two balanced or unbalanced outputs and available phantom supply input.
Its ultra-low distortion and low noise performance make it the best choice, even when larger preamps could be used. The single-ended supply input range is from 24 to 33VDC. Operation from 12VDC is possible with a 6dB reduction in headroom. Each output drives high or low impedance loads.
