Adjusting the SOUND FIELD program
Understanding the Digital Parametric Equalizer
The parametric equalizer is a tone control system with
adjustable center frequency and slope (Q).
The STR-
D2090/STR-D1090 provides flexible equalization using one-
band parametric equalizer with center frequency and
slope, and 2-band shelving equalizers with adjustable
turnover points.
The equalization curve appearing on the display allows you
to accurately adjust the sound quality. The parametric
equalizer effects all line output signals including
SURROUND (REAR), CENTER.
