Microphone/Transducer
Audio Input Transformers

Used for Professional Sound Studios
Broadcast Mixing Consoles
Control and Instrument Amplifiers

 

  • Large step-up ratios with flat frequency response over the entire audio range.
  • Gapless laminations provide wide bandwidth with extremely low distortion. Use of two magnetic shields made with extra thick mu-metal and gapless core provide negligible hum pick up. All units provided with electrostatic shield.
  • Your choice of two package styles, stud mounting with flying leads or low profile thru hole. Identical electrical performance regardless of package style.
  • Frequency response _1 dB, 30 Hz - 15 kHz.
  • Low profile thru hole (24000 series) manufactured to MIL-PRF-27, Grade 5, Class R.
  • Because of gapless laminations, unbalanced DC current should be avoided.
  • Typical distortion of 1% at power level of 0 dBm (1 Milliwatt), 30 Hz - 15 kHz. If the low frequency is raised, the power level for 1% distortion is as follows:

    • 50 Hz - 3 Milliwatts (4.7 dBm)
      100 Hz - 10 Milliwatts (10 dBm)
      300 Hz - 150 Milliwatts (21.7 dBm)

    All units have two extra thick mu-metal shields.
