General description
The DEQX PreMate is a versatile preamplifier and digital signal processor focused on improving the sound quality of existing audio systems. With advanced speaker and room correction, the PreMate provides accurate reproduction of music, correcting timing and phase errors. This results in a clear and balanced sound.
In addition to its correction functions, the PreMate acts as a high-quality DAC and preamplifier. With various digital and analog inputs, the device is compatible with a variety of audio sources. The PreMate also supports streaming via USB and is integrated as a Roon endpoint, providing a seamless music experience.
Using the PreMate requires an initial calibration to measure and correct for the specific characteristics of the speakers and listening room. This process can be performed using the included measurement microphone and software, or with the assistance of a specialist. After calibration, the PreMate provides improved sound reproduction tailored to the unique characteristics of the listening environment.
Background information
The DEQX PreMate was designed with the philosophy that speakers and acoustics are as important as equipment itself. The Australian DEQX team, led by lead designer Kim Ryrie, combined digital speaker and room correction with a high-quality digital/analog preamplifier design. The enclosure is aluminum; internally, DEQX uses high-quality components for minimum distortion and maximum resolution.
Brand history
Founded in Australia in 1997, DEQX developed the HDP-1, a digital processor intended for loudspeaker and room calibration. The technology is based on correcting loudspeaker characteristics in the digital domain before digital-to-analog conversion. The first product became available in 2002, with digital correction of phase, frequency response and timing. DEQX released a series of processors with a focus on accurate reproduction of sound signals. Subsequent models include the HDP-3, HDP-4, Premate and Mate, which enable features such as multiple digital and analog inputs, automatic and manual calibration and subwoofer integration. DEQX processors use measurement of impulse response and minimum phase correction. The products are used in systems where time, phase and frequency response correction is desired. The latest generation, the Pre-4, was announced with improved AD/DA conversion and new calibration software, DEQX Calibrated™.
Questions & Answers
How can the DEQX PreMate help correct speaker and room response?
The PreMate uses sophisticated algorithms to correct both amplitude and time response of speakers, then applies room EQ to minimize acoustic anomalies.
What inputs and outputs are available on the PreMate?The PreMate features five digital inputs (Toslink, S/PDIF RCA, S/PDIF BNC, AES/EBU XLR and optional USB), two analog inputs (RCA and balanced XLR) and outputs for both main and subwoofers via RCA and XLR.
How is the PreMate operated?The PreMate is controlled via a remote control that allows volume, 3-band tone control and storage of up to 99 EQ profiles.
Is it possible to integrate subwoofers with the PreMate?Yes, the PreMate can seamlessly integrate one or two subwoofers and offers precise time alignment for optimal performance.
What digital audio formats does the PreMate support?The PreMate supports 24-bit audio with sample rates ranging from 44.1 kHz to 192 kHz, depending on the input used.
Can the PreMate be used with both passive and active speakers?The PreMate is designed for use with passive speakers and uses their built-in crossovers.
How is the PreMate connected to a computer for configuration?The PreMate is connected via the USB Control port to a computer running the DEQX-Cal software for configuration and calibration.
What is the difference between the PreMate and the PreMate Plus?The PreMate Plus has a touchscreen on the front panel, an Ethernet port for network streaming (Roon and DLNA) and 12V trigger outputs, while the standard PreMate does not have these features.
How accurate is the PreMate’s room EQ?The PreMate’s room EQ offers seven or 10 bands, with frequencies from 1 Hz to 48 kHz, and adjustments from -300 to +40 dB, with a Q factor from 0.01 to 17.
Is the PreMate compatible with Roon?The standard PreMate is not Roon Ready; only the PreMate Plus offers Roon integration via the Ethernet port.
