CMT 55 (O)
Inspired by Schoeps® CMT 55 (Omnidirectional)
Template: Modern Royer style ribbon (active) in Omni/ambient mode
acronym:
- O = Omni (omnidirectional) takes sound from all directions
WHAT MAKES IT SPECIAL
It keeps the heat ribbon adds much more three-dimensional real environment
SOUND CHARACTER
- low full but natural
- medium very open
- high soft but present
- answer very spatial and realistic
in practice: more natural than CMT55 (C) more open than C4038 less bright than a 414
TIMBRIC PERSONALITY
it's a mic:
- very natural
- very three-dimensional
- very musical
- not very aggressive
perfect for: clean ambient studio layer
cleanambientrecording
Controls
Axis Interaction
almost irrelevant
- 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 6–10”: ambient
Low (dB)
full but controlled bass
use:
- 0 → natural
- 1 → tighter
High (dB)
use:
- 0 → perfect
- +1 → more air
- rarely beyond
Delay (ms)
Useful for: Creating deep 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: ribbon omni
- character: natural / spatial
- strength: realism
- limit: little attack
ON DARK CAB (PPC, Orange)
EXCELLENT opens without harshness
ON MODERN CABs (VHIII, 6505)
it makes it more natural and less digital
ON VINTAGE CAB
perfect disco sound
ON HI-FI CAB (TVX, SW Giant)
risk: → too widespread → poorly defined
PRO
very natural, very musical, three-dimensional, excellent for study
AGAINST
little attack, not very defined, not ideal alone for metal
