UAD Powered Plug-Ins Manual - 449 - Chapter 44: Precision Limiter
with 20-20 kHz pink noise on an SPL meter set to C-weighted slow (i.e. aver-
age) response. It is this calibrated meter/monitor relationship that establishes
a consistent average “perceived loudness” with reference to 0 dB on the
meter.
Sliding Meter Scale
With the K-System, programs with different amounts of dynamic range and
headroom can be produced by using a loudness meter with a sliding scale,
because the moveable 0 dB point is always tied to the same calibrated mon-
itor SPL. The Precision Limiter provides several meter ranges for various types
of program material (see
“Type” on page 449
).
Long Live Dynamic Range!
The K-System can help combat the bane of the “loudness wars” which is all-
too common in today’s music, whereby material is made to appear louder
when compared to other material at the same playback volume, at the ex-
pense of dynamic range and fidelity.
Type The Type switch defines the 0 dB point in the meter scale (see
“Sliding Meter
Scale” on page 449
). There are three different K-System meter scales, with
0 dB at either 20, 14, or 12 dB below full scale, for typical headroom and
SNR requirements of various program materials.
