Product Description
RDL STM-2 Adjustable-Gain Microphone Preamplifier
Overview
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 STM 2 supply input is single ended and operates from 24 Vdc. Operation from 12 Vdc is possible with a 6 dB reduction in headroom. Each output drives high or low impedance loads.
