DEQX HDP Express II

 

HDP-EXPRESS II Preamp processor


 

Master the art of timing
DEQX processors correct the distortion that all speakers make—electro-mechanical devices that they are—and offer room compensation as an added extra. While righting frequency-response errors as other units do, they also uniquely fix critical timing errors by adjusting thousands of frequency groups so that they arrive on time.

Other ‘room correction devices’ simply adjust amplitude response (uneven output at different frequencies) to offset room modes. But they can’t address the fine details of phase coherence; the group-delay timing issues that manifest in all real-world speakers.

The results are startling; two-channel and surround systems open up in a dramatic way when timing, phase and amplitude accuracy are restored to the speakers, with judicious room compensation added.

 

DEQX HDP-Express II™
The Express II packs much of the new technology of our flagship HDP-4 Preamp Processor in a new, extraordinarily cost-effective design. The Express II uses professional-grade components and power supplies but we’ve kept the price of the Express II down by moving the front-panel controls to the remote while deleting the HDP-4’s balanced analog and digital outputs for a simpler chassis.

Like its predecessor, the Express II provides DEQX Inline™ correction for your existing speakers, room and media. Plus, it does the impossible and precisely integrates one or a pair of subwoofers.

The Express II also supports 2- or 3-way active speakers for those opting for DEQX XO™ Active configurations with DEQX’s linear-phase crossovers, now or in the future.

The Express II offers four hi-resolution digital inputs, accepting sample-rates including 24-bit/192k and two analog inputs (balanced XLR and single ended RCA) with 96k analog-to-digital conversion.

Measure (and correct) speakers first, then the room
In correcting the speakers—before the room—our comprehensive DEQX-Cal™ software generates correction filters for phase, timing coherence and frequency-response. Only then does DEQX-Cal measure from the listening area for room correction.

DEQX technology is unique
It corrects speaker frequency-response and timing errors by adjusting thousands of frequency groups, depending on your speakers’ measure­ments, so that they arrive at the correct time.

Traditional analog and digital EQ corrupts the timing coherence around the frequencies that they’re trying to equalize for volume. DEQX Processors slow down on-time and early-arriving frequencies so that slower frequencies can catch up.

That just can’t be done in the analog domain!

DEQX uses real computing horsepower to make that happen with a 240-megaflop, 32bit floating-point Digital Signal Processing Engine that essentially achieves zero distortion.
