Report: Verdin Carillon — "Manual Extra Quality"

3.2 Acoustic (Physical) Bell Tuning

  • Strike point check: Mark the optimal 22.5° from the bell’s crown. Hitting dead center or near the rim degrades partials.
  • Hammer rest gap: Set to 3–5mm from bell surface. Less causes double-strikes; more adds latency and uneven force.
  • Clapper/hammer material: Verdin’s PTFE-coated brass hammers yield best articulation. Replace worn felt or leather tips immediately—hard spots cause metallic “thwack.”

1. The Mechanical Era (Pre-1960s)

These systems use physical pin barrels, weights, and strikers. The manuals here focus on friction points and leather hinge maintenance. Extra quality means high-contrast images of gear assemblies.

Likely meaning

  • "Manual" — manual keyboard or baton-played carillon action (as opposed to fully automated/electronic play).
  • "Extra Quality" — upgraded grade of parts/finish: better bearings, hardened linkages, precision-machined clappers, superior leather/rope/felt materials, corrosion-resistant finishes, tighter tolerances, and possibly tuned or higher-grade bronze alloy bells.

Annually (Factory or Certified Tech)

  • Full tuning calibration (digital: resample strike files; acoustic: restrike torque on bell bolts).
  • Backup Verdin OS configuration (including custom velocity maps).
  • Check tower speaker cable resistance – >0.5Ω difference between runs degrades phase coherence.
