Self-noise is 12 dB(A), maximum SPL is 145 dB (155 dB with pad), and the frequency response spans 20 Hz to 20 kHz with a flat, studio-accurate curve. It includes switchable 80 Hz high-pass and 10 dB pad. Ships with a shockmount and protective case. Requires 48V phantom power.

  • Cardioid condenser XLR, requires 48V phantom power
  • Self-noise 12 dB(A), maximum SPL 145 dB (155 dB with pad)

Our take

The AT4040 is where Audio-Technica drops the budget constraints and builds a genuinely professional microphone. The flat frequency response is honest and detailed without hyped presence peaks - this is a mic that flatters good audio technique rather than papering over bad recording conditions. The 145 dB SPL ceiling is overkill for podcasting but makes it a multi-purpose studio tool. Expect to spend time treating your room, because this mic hears everything.

Pros

  • Flat, honest studio-grade frequency response
  • High maximum SPL with pad - versatile beyond podcasting
  • Shockmount and case included - ready to record
  • Consistent, repeatable performance across units

Cons

  • Condenser sensitivity demands acoustic treatment
  • Requires 48V phantom power
  • Single cardioid pattern - no polar pattern switching
