Introducing the DEQX Cloud
The DEQX Gen4 processors interface over the network to the DEQX Cloud™. The result is intuitive, cross-platform, zero-install speaker calibration and room correction.
Stunning audio performance
An ESS Sabre Pro ADC and DAC embedded in our custom circuitry and ultra-low noise power supplies deliver –115 dB THD+N (preliminary) from analog input to analog output. Our most transparent audio processor ever.
Unlocking next-gen performance
DEQX Gen4 massively surpasses our previous models in processing horsepower. A powerful hexacore ARM processor delivers higher time-domain resolution and better low-frequency phase resolution.
Unsurpassed usability
We've refocused on hardware usability, with a carefully selected set of features for each model, a large volume control with LED readout and 5.5-inch AMOLED touchscreen with customised glass front.
