ESI Operation Manual
3. Headroom/Boost
Headroom is the amount of dynamic range remaining before clipping
will occur. Sampling instruments are quite different from a CD player,
since a sampler plays multiple channels at once. Each channel boosts the
headroom requirement by 3 dB. The amount of headroom on the ESI is
adjustable from 0 dB to 15 dB in 1 dB increments (with the front panel
volume control set to maximum). A headroom setting of 0 dB for
example, will provide the hottest output level, (and the highest signal to
noise ratio) but may cause “clipping” if too many notes are played at
once. The default headroom setting is 3 dB, which maintains an excel-
lent signal to noise ratio while keeping a reasonable amount of head-
room in reserve. If you hear clipping from the ESI, raise the amount of
headroom. The headroom setting is retained when power is switched off.
1. Activate Master/Global module.
2. Select Special (8), Headroom (3).
3. Select the desired amount of headroom. The amount of remaining
headroom is variable from 0 dB to 15 dB in 1 dB increments.

Each channel played adds +3 dB to the output level. Increase the headroom to prevent clipping.
✱
Tip: The headroom adjustment also
controls the level on the optional S/PDIF
digital audio output.
