Product Description
HDP-4™ Preamp processor - DEQX processors correct the distortion that all speakers make—electro-mechanical devices that they are—and offer room compensation as an added extra. While righting frequency-response errors as other units do, they also uniquely fix critical timing errors by adjusting thousands of frequency groups so that they arrive on time.
Other ‘room correction devices’ simply adjust amplitude response (uneven output at different frequencies) to offset room modes. But they can’t address the fine details of phase coherence; the group-delay timing issues that manifest in all real-world speakers.
The results are startling; two-channel and surround systems open up in a dramatic way when timing, phase and amplitude accuracy are restored to the speakers, with judicious room compensation added.
