World-class digital preamp processors combined with DEQX's renowned "speaker first, then the room" calibration and correction. Now available with touchscreen control panel and network audio streaming.
Calibrate the speakers first...
DEQX uses real measurements of each individual speaker to generate a precise correction filter that restores the amplitude and timing coherence of the acoustic signal from the speakers. DEQX correction works with regular speakers and multi-amped active speakers.
Only after the individual speakers are calibrated for true high fidelity does DEQX correct for the room's acoustic modes — resonances present in all listening rooms that muddy and confuse the bass region.
