Radio Design Labs STM-2X Switched Microphone Preamplifier - 35 to 65 dB gain

Features:

  • Quiet Switching of Condenser Microphone
  • Remote Microphone Soft-Switching
  • Switch a Mic-Level Source to a Mic or Line Level Output
  • Remote Toggle Switch or Push-to-Talk Button
  • Adjustable Preset Gain on Microphone Source

 

The STM-2X is the ideal choice in many installations where a microphone preamplifier is required, and is the ideal choice where either a toggle-type switch or push-to-talk switch is to be provided for microphone control, particularly if condenser microphones are used.
