- RDL STM-1 Microphone Preamplifier - 50 dB Gain
The STM-1 is a low-cost, high-quality miniature wall and surface mount microphone preamplifier from RDL, 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 50dB gain to bring any microphone-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 33VDC. Operation from 12VDC is possible with a 6dB reduction in headroom. For intercom applications, the input will operate directly from a speaker.
- Wall-mount high or low impedance input microphone preamplifier
- Fixed 50dB gain for consistency
- Balanced or unbalanced output
- Phantom power capability
- RF-filtered inputs and outputs
- STICK-ON convenience
