During the vinyl era, engineers faced a unique physical limitation, the cutting stylus.
Sharp transients and bright high-frequency content could cause excessive acceleration of the cutter head.
If the acceleration became too extreme, the head could distort, overheat, or even skip the groove entirely.
A simple solution was to roll off the top end, but that killed brightness and presence.
To preserve musicality, engineers developed smarter methods to control acceleration without dulling the signal.
You can now explore and understand how it works, with new presets and documentation designed around this feature.
