4-channel Microphone Power Supply Type 2829 is designed for acoustical systems where robustness and reliability are important. It is a simple power supply that introduces negligible noise into the measurement system.

  • Stackable
  • Powers up to 4 microphone channels simultaneously
  • Enables the functionality of the microphones and preamplifiers to be checked using CIC and TEDS
