What's included

DEQX hardware unit

Your ordered DEQX hardware unit. Every single DEQX unit is individually tested before leaving the factory.

Calibration kit

A Standard Calibration Kit is included with every DEQX. The Reference Calibration Kit is an optional upgrade.

Software USB stick

Includes the DEQX-Cal™ installer, microphone calibration files, and a PDF version of the user manual.

What is the difference between the PreMate and the PreMate Plus?

Compared to the PreMate, the PreMate Plus has a display/control touchscreen on the front panel, an Ethernet port for network audio streaming (Roon and DLNA), and 12V trigger outputs.

What is the difference between the PreMate and HDP-4?

The PreMate does not have the "High" outputs (used for tweeters in HD-Active systems), and has only a single digital output (the HDP-4 has four digital outputs).

Should I use subwoofers?

In addition to the obvious advantage of extending bass response, the DEQX approach to subwoofer integration also highpasses the main speakers. This reduces cone excursion, thus reducing distortion and increasing resolution!

Can you calibrate the speakers (and subwoofers) for me?

Yes! We can. In fact, we include it for free when you buy a DEQX. Be sure to book your first DEQXpert session soon after receiving your new DEQX to make sure you get the best out of it.
