DEQX units process the audio signal prior to power amplification so that the frequency and
phase-response is corrected, while optionally incorporating linear-phase ‘active’ crossovers into
the correction filters. This process involves three steps:
• Measurement • Correction • Configuration
The DEQX unit is linked via USB to a PC or Windows based Mac running the DEQX-Cal™
application. Using a calibrated microphone each speaker is measured and the DEQX-Cal™
software analyzes its Impulse-response, which provides its frequency-response (amplitude at all
frequencies) and Phase-response (timing coherence across all frequencies, or ‘Group Delay’).
DEQX-Cal™ then provides the required ‘time and frequency’ domain correction filters for the
speakers, which may optionally include active crossover filters.
Various combinations of Speaker-correction filters, Room-correction EQ and Preference EQ
settings can be saved to four PROFILE memories in the DEQX unit, where they can be selected
using the front panel buttons, the remote control or the PC running DEQX-Cal™ software.
Installing and setting up a DEQX unit involves:
*Connecting the DEQX unit to your system (see DEQX unit User Manual)
*Installing and Launching DEQX-Cal™ software on a Windows PC or Mac PC running Windows
*Connecting the DEQX unit via 5-metre USB cable provided to your PC or Mac running Windows
*Choosing the configuration suitable for your sound system, such as passive speaker with
optional subs, or 2-way active with subs, or 3-way active
*Installing the DEQX-Calibrated™ microphone calibration file (optional)
*Measure speakers (one speaker can provide a ‘generic’ model correction) using the
Measurement Wizard
*Creating Correction Filters for speakers from their measurements using the Calibration Wizard
*Configure the DEQX unit for your requirement: e.g. Passive speakers plus sub/s, OR 3-way
active etc using the Configuration Wizard
Skills necessary to operate DEQX-Cal™ software include basic Windows skills, such as
launching applications, using menus and dialogs, and file management. These are not covered in
this guide. This manual provides a reference for the software operation with hints relating to
achieving the best results.
