414B (75Hz O)

Inspired by AKG® C414B (Omnidirecitonal, 75Hz Bass Cut)

Model of: AKG C414 (multi-pattern capacitor)

acronym:

  • 75Hz = light low cut (more body than 150Hz)
  • O = Omni (omnidirectional)

SOUND CHARACTER

  • low more natural and present
  • medium open
  • high air and space
  • answer very three-dimensional

in practice: fuller than 150Hz OR more natural than less aggressive cardioid

TIMBRIC PERSONALITY

it's a mic:

  • very natural
  • very spacey
  • very balanced
  • little "in your face"

perfect for: clean ambient studio double mic

cleanambientrecording

Controls

Axis Interaction

little impact (omni)

  • ON → slightly more focus
  • OFF → more widespread

Gain (dB)

  • volume only

Mic Distance (inch)

  • Distance 0–1”: not very useful
  • Distance 1–3”: Direct but open
  • Distance 3–6”: natural
  • Distance 6+: ambient

Low (dB)

more present bass than 150Hz

you can:

  • leave flat
  • or -1 if too full

High (dB)

very sensitive

use:

  • 0 → natural
  • +1 → air
  • over → too bright

Delay (ms)

Useful for: Creating real depth multi-mic combinations

Ambience (Y/N)

almost always ON

Amb Level (dB)

  • low → natural
  • medium → study
  • high → ambient

Amb Size (ms)

  • 40–80 → study
  • 80–120 → large

Pro Tips

QUICK SUMMARY

  • type: omni capacitor
  • character: natural / spatial
  • strength: realism
  • limit: little attack

ON DARK CAB (PPC, Orange)

EXCELLENT opens without losing body

ON MODERN CABs (VHIII, 6505)

more natural less “digital”

ON VINTAGE CAB

perfect disco sound

ON HI-FI CAB (TVX, SW Giant)

risk: → too ambient → poorly defined

PRO

very natural very realistic more body than 150Hz excellent for studio

AGAINST

less defined, not very aggressive, not suitable for direct metal
