The STM-3 is a high quality, miniature wall and surface mount low-noise microphone preamplifier from RDL, designed for use in surveillance, commercial sound, broadcast and recording where higher than normal gain is required.

The unit is very flexible, with gain adjustment from 45 to 75dB, two balanced or unbalanced outputs, and available phantom supply input. Its 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 32VDC. Operation from 12VDC is possible with a 6dB reduction in headroom. Each output drives high or low impedance loads.
