Legacy Product Support

Here at DEQX, we pride ourselves on our commitment to long-term support of our products. The DEQX-Cal software is compatible with all DEQX processors from the HDP-3, HDP-4 and HDP-5, and back to the original PDC-2.6, and many original DEQX processors have been in the field for well over two decades and continue to be used daily.

User Manual

The DEQX User Manual is a comprehensive guide to installing and connecting up your DEQX. It also includes full details on how to use the new DEQX-Cloud setup software. While your initial DEQXpert session will perform your calibration for you, all the information is there for you should you wish to do your own room measurements, or even to recalibrate your speakers yourself.
