What is the RDL STM-2X?

The RDL STM-2X is a switched microphone preamplifier with adjustable gain of 35 to 65 dB at its line output. It suits installations where a toggle or push-to-talk switch controls the microphone, particularly with condenser mics.

How does it work?

RDL STM-2X Switched Mic Preamp, 35 to 65 dB Gain

The preamplifier quietly soft-switches the microphone source using a remote toggle switch or push-to-talk button. It provides both a +4 dBu balanced line output and a -45 dBu balanced mic-level output, so it can feed either type of input. Filtered 24 Vdc IEC phantom is available for condenser microphones. It runs from a 24 Vdc supply such as the RDL PS-24AX 24 Vdc power supply, and STICK-ON modules mount in the RDL STR-19B racking system or on a rear rack rail with the RDL ST-RRB1 rear rack rail kit.

What are the key features?

  • Quiet mic switching — Soft-switching avoids pops when condenser microphones are turned on or off.
  • Remote control — A remote toggle switch or push-to-talk button controls the microphone.
  • Mic or line output — Balanced outputs at +4 dBu line level and -45 dBu mic level are provided.
  • Adjustable gain — Line output gain adjusts from 35 to 65 dB to match the microphone.
  • Filtered phantom — 24 Vdc IEC phantom is available for condenser microphones.
