Treble Control
Treble control lets you raise or lower the level of high-frequency sound: the treble.
A “Yes” means the user can adjust those frequencies. Boost raises their level; cut lowers it. Adjustable high-frequency bands in an equalizer can provide this feature without a separate Treble knob.
Treble Control — Preamp
In a preamp, treble control changes the tonal balance of the listening signal, rather than simply turning everything up. If treble sounds too strong, try cutting it; if too weak, try boosting it. Neutral applies no treble boost or cut.
If adjustment has no effect, check the manual: Direct or tone-bypass mode may disable it. Two preamps marked “Yes” need not produce the same change. Compare the boost/cut range in decibels (dB), which express the level change, and the frequencies affected—not just the range number.
