Inspired by Sennheiser® MD421 (Bass Roll-Off Switch 2)

acronym:

  • LC2 = Low Cut level 2 (medium low cut) more filtered than LC1 less lows, more control

WHAT CHANGES COMPARED TO LC1

the MD421 has a 5-position high-pass filter that progressively reduces low frequencies (Recording Hacks)

LC2 = sweet spot between body and definition
