Audio-Technica MB 4k
Cardioid Condenser Microphone
The MB 4k is an inexpensive vocal condenser microphone from Audio-Technica’s Midnight Blues series.
The mic uses an electret condenser element. The low power requirements of this capsule allow the mic to be powered by either 48V phantom, or a 1.5V AA battery (which fits into the mic handle).
When running on battery power, the mic’s specs change:
| Battery | Phantom | |
| Sensitivity | 3.9 mV/Pa | 5 mV/Pa |
| Impedance | 250Ω | 200Ω |
| Max SPL (1% THD) | 125 dB | 137 dB |
The mic’s body construction is all metal, with a “soft touch” finish an an on/off switch.
Two versions of the mic are available; the MB 4k/c includes a 15-foot XLR cable.
The Audio-Technica MB 4k is also known as: MB4k.
