The STM‑1 is a low‑cost quality microphone preamplifier designed for use in commercial sound and broadcast applications. The compact size makes it ideal where a larger or heavier preamp cannot be used. The high‑performance circuit provides a fixed 50 dB gain to bring any mic‑level signal up to the line‑level range of nearly any line input. The STM‑1 supply input is single ended and operates from 24 to 33 Vdc. Operation from 12 Vdc is possible with a 6 dB reduction in headroom. For intercom applications, the input will operate directly from a speaker.
