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.

After Correction Before Correction

Audiophile-grade engineering

Every aspect of a DEQX is carefully engineered for optimum audiophile performance. For example: countless design, development, and auditioning iterations were put into the latest A/D convertor circuit and the DAC's I/V (current to voltage) convertor circuits. Over a decade of constant refinement and attention to detail has paid off in superlative performance.

Now add in superb digital coding and algorithms: a −140 dB digital processing noise floor and a precision digital volume control. The end result? A truly transparent component with zero digital artifacts. An "analog" sound for all combinations of input to output: analog to analog, digital to digital, and any combination of the two.

The heart of your system

DEQX preamp processors feature unrivalled functionality and connectivity. In many cases a single DEQX processor will replace multiple boxes, simplifying your system as well as adding functionality and increasing system performance.

What the reviewers say

Digital Audio Review

The audible improvements are more pronounced than switching up cables, server/streamer, DAC or amplifier. Such is the power of low-latency group delay correction through DSP. Australians say “Maaate”, I say “Bloody marvellous!”.

Positive Feedback

What the DEQX does is create a great presence and separation—in all respects. Instruments become more believable and there. There as in the sense of being there before you… clear and out in an open and 'cleanly' delineated space.

I am unequivocal about my enthusiasm for the speaker-calibration capabilities of the DEQX PreMate. It made my very good speakers undeniably better, smoother and cleaner, and endowed them with a bigger soundstage. It made dense, complicated music easier to resolve, and all music more of a joy to hear.

I now have all of the detail, dynamics, smoothness and spatial attributes I have been searching for with the ability to do room correction and frequency shaping as I wish.  It is a win-win for me.
