Master the art of timing
DEQX processors and preamp processors are thoroughly-engineered DSP platforms packed with innovative, patented calibration technology for the most inaccurate components in your system: your speakers and their integration with room acoustics.
Speakers actually introduce more forms of errors and distortions than every other audio component in your system combined! In fact they introduce 10 to 100 times more errors in timing, phase and frequency-response than the signal driving them. The result is a massive loss of resolution and realism.
DEQX removes many of these speaker distortions and then applies room compensation to minimize masking due to room resonances and other factors. DEQX restores timing errors by adjusting thousands of frequency groups — depending on the speakers’ measurements — so they all arrive at the correct time. This requires delaying more ‘on-time’ frequencies so the laggards can catch up. At the same time it calibrates the speaker’s frequency-response to a degree its manufacturer never could without a way to compensate the signal driving it.
DEQX ‘Room calibration’ measures the resonances and other effects of your room’s acoustic. Calibration focuses on correcting lower frequency abnormalities cased by the room’s dimensions and speaker placement. In some configurations timing and phase calibration can also be addressed.
The results are startling; two-channel and surround systems open up in a dramatic way when timing, phase and amplitude accuracy are restored to your speakers with judicious room compensation an added plus.
As a full-function preamp processor the PreMate+ follows the Hippocratic Oath: “First do no harm”! With processing distortion 140dB below listing level the notion of digital or analog sound doesn’t exist in the DEQX Universe; we let the music or soundtrack speak for itself.
PreMate+ adds an attractive 4.3” touch-sensitive intelligent display to the reference PreMate+ design. A 1GHz ARM CPU drives the display and allows future Internet connectivity. The touch screen has several display pages for customized control options including volume, analogue metering, selection of input source, and calibration and EQ profile selection.
PreMate+ delivers the same comprehensive speaker and room calibration features and the same HD audio quality as DEQX’s flagship HDP4 and HDP5. While the HDP-4 and HDP-5’s active crossover features can be used with either active or passive speakers the PreMate+ works with passive speakers using their built-in crossovers and allows the option to add time-aligned subwoofers. It also allows bi-amping and detailed room calibration of bi-wireable speakers.
The preamp section includes seven inputs. DEQX’s renowned USB input has a dedicated 500mHz DSP with a proprietary asynchronous re-clocked and re-buffered digital input stage that provides state-of-the-art playback from PC or Mac music servers. Other digital inputs are Toslink Optical, RCA Coax, BNC Coax and balanced AES3 XLR. Two analog inputs are RCA and balanced XLR for analogue sources such as vinyl, surround receivers or other analogue sources. Outputs are RCA unbalanced and XLR balanced for main speakers, subwoofers and bi-amped speakers. The main speaker output is also available in S/PDIF digital.
Stereo or surround:
For surround systems a single stereo PreMate+ can make a dramatic improvement to soundtrack music, which is mainly mixed to main front left and right speakers. The unit will also properly integrate one or two subwoofers. For ultimate surround systems PreMate+ acts as ‘master’ to one or more ‘slave’ 2-channel units for center and surround channels. For example, a PreMate+ as master plus three Express-II units provides an extraordinary 7.1 or 7.2 surround sound experience.
PreMate+ incorporates Cirrus Logic’s reference-grade Pro Audio ADC (Analog-to-Digital Converter) to provide the most transparent analog input you’re likely to hear. Two new generation 32-bit Burr Brown DACs (Digital-to-Analog Converters) combined with PreMate+’s transparent calibration engine provide analog fluidity that’s turned digital skeptics into true believers.
And the list goes on...
PreMate+ takes many features from our flagship HDP-4 and HDP-5 Preamp Processors including the same audiophile-grade parts and new technology.
The remote control provides volume and 3-band forensic tone control with 99 memories for special recordings, low volume listening, certain record labels, and basic bass/treble cut and boost instantly as needed.
Need more bass? Integrate one or two subwoofers into your system with properly time alignment main speakers and room compensation.
Choose from four customized preference profiles, each can contain entirely different calibration filters for both the speaker and room preferences to allow instant comparisons including ‘bypass’ to remind you of what you were hearing before.
Calibrate speakers first then the room with our help.
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 calibration.
Your dealer or our DEQXpert™ on-line installation service drives the set-up software for you. All you have to do is connect up the unit much like any preamp-DAC, then set up the calibrated microphone to measure the speakers, then your room as we suggest during our live DEQXpert(TM) hook-up. The processor then computes the precise calibration for your particular system and room; there’s never been a preamp like this!
If you don’t have a local dealer to install the PreMate+ a DEQXpert agent can run the comprehensive DEQX Cal™ software for you for a surprisingly affordable price on a secure, remote connection. You’ll need a simple USB link to your PC (Windows compatible computer or Mac running Windows) using a measurement microphone and a broadband connection. Or, if you prefer to calibrate it yourself, we can lend a hand via email or phone with tips and directions on getting the best from your setup.
