Description
The STM-2 is a quality low-noise microphone preamplifier designed for use in commercial sound, broadcast, and recording. The STM-2 is very flexible, with gain adjustment from 35 to 65 dB, two balanced or unbalanced outputs, and available phantom supply input. Its ultra-low distortion and lownoise performance make it the best choice, even when larger preamps could be used. The single-ended supply input range is from 24 to 33 Vdc. Operation from 12 Vdc is possible with a 6 dB reduction in headroom. Each output drives high or low impedance loads.
