Wondering how the Muffsy MC Head Amp measures? Look below for the numbers.

  • Topology: Dual mono
  • Gain: 24.6 dB
    • 0.3 mV input = 5 mV output
    • 0.5 mV input = 8.5 mV output 
  • Input impedance: 47 - 100 ohms, in four steps
  • THD: < 0.1 % *)
  • THD+N: < 0.6 % *)
  • SNR:  71.8 dB, referenced to 0.5 mV input @ 1 kHz
  • Frequency Response: +0.0 / -0.1 dB (20-20.000 Hz)
  • IMD (ITU-R): 0.001 %
  • DC Offset: < 0.1 mV
  • Dynamic range: > 110 dB, referenced to 0 dBV output
  • Power requirements: +/- 15V at < 50 mA
  • PCB Size: 84.0 x 59.4 mm / 3.3 x 2.3 in

*)The inherent noise in my signal generator is too high too accurately measure the THD and THD+N. I'm looking at how to solve that. The numbers are too high, both should be well below 0.1%, but I've added my measurements for reference anyway.
