Product Overview

Radio Design Labs' 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 off to +65 dB, two balanced or unbalanced outputs, and available phantom supply input! Its ultra-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 12 to 33V DC! Each output drives high or low impedance loads. The durable bottom adhesive permits quick, permanent mounting nearly anywhere–or use it with RDL's racking accessories.
