Inputvolumen

Inputvolumen refers to the level or amplitude of a signal as it enters an electronic device or system. In audio engineering, it describes the amount of signal that is allowed into a preamplifier, mixer, interface, or processor. It is distinct from output volume, which controls the level after processing. Proper setting of inputvolumen affects signal quality, noise, and headroom: too high can cause clipping and distortion; too low can increase the relative impact of hiss and noise and may require subsequent stages to boost gain.

In hardware, inputvolumen is typically controlled by an input gain knob or trim control on a microphone preamplifier, audio interface, or mixer channel. In software, the corresponding control appears as input gain or track gain, shaping the signal before effects and conversion. Digital audio workstations show input level with meters in dBFS; practical guidance suggests aiming for peaks well below 0 dBFS, often around -12 to -6 dBFS to leave headroom.

Measurement involves peak and average levels (RMS). Matching the source level and the device’s headroom prevents clipping and excessive noise. Trade-offs exist: higher inputvolumen improves the signal-to-noise ratio of quiet sources but reduces dynamic range if clipping occurs; lower settings preserve headroom but can increase noise.

Etymology: Inputvolumen blends English “input” with Latin-based “volumen.” In German, the term would typically be referred to as Eingangspegel or Eingangsvolumen, depending on context.
