RDL STM-2 Adjustable Gain Microphone Preamplifier

Adjustable Gain Microphone Preamplifier - 35 to 65 dB Gain 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.Features: Low-Noise Mic Preamp Adjustable Output Level High or Low Impedance Mic Inputs Mic Input to 2 Line Outputs Two Balanced or Unbalanced Outputs Phantom Capability RF-Filtered Inputs Specifications: Input:500 Ω balanced; 5 kΩ unbalanced Phantom:24Vdc; IEC 1938: 1996-12, Filtered Outputs (2):+4 dBu 150 Ω balanced; -10dBv unbalanced Frequency Response:50 Hz to 20 kHz (+/- 1.5 dB
