U87 (LC O)
Inspired by Neumann® U87 (Omnidirecitonal
Model of: Neumann U87
acronym:
- LC = Low Cut active
- O = Omni (omnidirectional)
therefore: it picks up from all controlled low directions
WHAT CHANGES COMPARED TO THE OTHER U87s
- controlled ambient
- less low than pure Omni less “mud” more usable
SOUND CHARACTER
- low natural but controlled
- medium very open
- high sweet and airy
- answer extremely three-dimensional
in practice: very realistic, very "room-like", less muddy than the pure Omni
TIMBRIC PERSONALITY
it's a mic:
- very natural
- very spacey
- very balanced
- not very aggressive
perfect for: realistic clean ambient studio recording

Controls
Axis Interaction
not very relevant (omni)
- ON → slightly more focus
- OFF → more widespread
Gain (dB)
very sensitive (capacitor)
Mic Distance (inch)
- Distance 0–1”: not very useful
- Distance 1–3”: Direct but open
- Distance 3–6”: natural
- Distance 6–10”: ambient
Low (dB)
already filtered
use:
- 0 → perfect
High (dB)
use:
- 0 → natural
- +1 → more air
Delay (ms)
fundamental for: simulating real space depth
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 / spatially controlled
- strength: realism
- limit: little attack
ON DARK CAB (PPC, Orange)
EXCELLENT opens without kneading
ON MODERN CABs (VHIII, 6505)
very natural less “in your face”
ON VINTAGE CAB
perfect disco sound
ON HI-FI CAB (TVX, SW Giant)
risk: → too widespread → poorly defined
PRO
maximum realism, very three-dimensional, less muddy than the pure Omni, perfect for studio use
AGAINST
little attack, poorly defined, not ideal for direct metal
