The large FL display, 14-band equalizer and 27-spectrum analyzer features
high visibility of information and make it possible to set EQ (equalizer) curves
with high accuracy.
MANUAL: Five preset patterns have been factory-preset for this mode, too. In
this mode, it is also possible to preset (assign) equalizer patterns
created by the user in place of the factory presets. @
REFERENCE: Five exemplary patterns have been preset at the factory. #
PARAMETRIC: Equalizer curves can be created by setting up to 3 center
frequencies and the equalizing levels for them. %
GRAPHIC: The equalizer curve can be adjusted in a detailed way for every
frequency range. It is also possible to fine-adjust a curve which
has been created in the PARAMETRIC mode. The GRAPHIC
mode is to be used when detailed adjustment of acoustic
compensation is required. &
A total of 30 playback patterns have been factory-preset by combining five
recommended equalizer patterns with six music genres, so that any of them
can be selected by actually comparing them. Similarly, selection from 30
types of recording patterns for playback on car stereo or from 30 types of
recording patterns for playback on headphone stereo is also available. Select
the optimum equalizer pattern according to the music genre and purpose of
use of the pattern. (
