Circa 2014. This is an DEQX  "legacy" unit but has many features! Read all about them here.

The PreMate can be described as an analogue preamplifier with a high quality built-in DAC also featuring the DSP powers that have made DEQX world-famous. It shares many of the features of DEQX’s flagship HDP4. The DEQX mandate for the PreMate was to provide an almost plug-n-play component that seamlessly integrates into existing audio enthusiasts’ systems without upsetting traditional and more conservative configurations.

For the more adventurous music lover the PreMate continues to provide fully customizable industry leading digital correction. At its most fundamental level the PreMate may be used as a high-quality preamplifier with a 32-bit resolution DSP volume control. It can accept a digital signal from a CD transport or computer audio via USB while also taking a balanced and single-ended analogue input. The various inputs can be switched remotely via the provided infrared remote control. The in-built high-quality PCM1795-based DACs then do the number crunching and pass it on to analogue line outputs for connection to the amplifier of your choice. Connectivity to an integrated amplifier would require setting the volume control to maximum and riding the levels on the PreMate with its high-resolution volume control, or vice versa.

PreMate™ delivers extraordinary resolution from both analogue and digital sources such as vinyl to HD 24/96 and 24/192 digital.

PreMate uses DEQX’s new generation low-jitter asynchronous re-clocking utilizing DSP memory to buffer and re-clock the audio in just a few milliseconds. This fluid analogue sound is further enhanced by PreMate’s virtually zero impedance multilayer PCB design that provides a noise floor that’s so low that one reviewer commented, “the noise floor is virtually sitting at the –140dB limit of the test analyzer”.

The PreMate accepts inputs from optical, S/PDIF and balanced digital sources that also utilize 32-bit floating point DSP re-clocking. For ultimate results its optional USB digital input entirely avoids the losses associated with encoding to and from S/PDIF. Instead a separate DSP regenerates original clock and data integrity that results in awesome bass and midrange authority.

Taking your system to its ultimate potential requires measuring and compensating for the inevitable timing- coherence, phase and frequency response errors that all loudspeakers introduce.

Need more extended bass? PreMate allows single or stereo subwoofers to be time/phase-aligned and calibrated with the main speakers. Steep crossovers relieve the main speakers from strong bass excursion that increases distortion. The crossovers also quarantine upper- bass output from subwoofers to maximize bass resolution.
