DEQX Calibrated™ processing
performs both room correction and 'anechoic' correction of
the loudspeaker by using two sets of measurement data. Room
correction can only realistically correct response below
about 500Hz. This is why DEQX uses its pseudo-anechoic speaker
correction to enable response to be corrected through the
mid range to above 20kHz in addition to room correction.
Note than most room correction systems can vary amplitude
(frequency response) but do not attempt phase correction;
those that do, also only correct phase in the lower several
octaves.
By combining both phase and amplitude correction
for the lower four to five octaves of the audio spectrum
using DEQX Room Correction with both phase and amplitude
correction for the upper six octaves by using DEQX Speaker
Correction, DEQX Calibrated™ is a unique enabling technology
resulting in the highest standard of linear audio playback
quality possible.
The DEQX PDC-2.6 processor also provides three-way
active digital crossovers and ten-band parametric equalization
for preset user preferences.
