Radio Design Labs STM-1
Microphone to Line Preamplifier

OUR PART #  STM1


Radio Design Labs' STM-1 is part of the group of STICK-ON products from Radio Design Labs. The STM-1 is a quality microphone preamplifier designed for use in commercial sound, broadcast, and recording applications. Its compact size makes it ideally suited for locations were a larger or heavier preamp cannot be used. Its performance makes it the best choice, even when larger preamps could be used. The single-ended supply input makes the STM-1 the ideal choice for both permanent and mobile equipment installations.
