Pro-Ject PJ65186400 Pre Box S2 Digital Pre-Amplifier – Black

The Pro-Ject PJ65186400 Pre Box S2 Digital marks a new era for our S-series components. For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding. It’s also the premiere of our proprietary Optimum transient digital filter and our proprietary clock circuitry design. Digital audio is the art of time, with our new proprietary clock design we have managed jitter rates of unrivalled 100 Femtoseconds, this also easily outperforms many renowned and respected audiophile clock generators!

With organic polymer capacitors and thin film miniMELF resistors we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of eight digital filters the sound can shape precisely to the listeners liking. Pre Box S2 Digital is fully remoteable, it can also control the playback software of a computer. You can use Play, Pause, Forward and Rewind straight with your Pre Box S2 Digital!

First class components from first class manufacturers!

ESS9602 – headphone amplifier and output buffer. Supports a dynamic range of up to 122dB and THD+N of -117dB with 600ohm loads for the Pro-Ject PJ65186400 Pre Box S2 Digital. Additionally, we implemented a unique feature that improves THD+N with 32ohm loads to -112dB in Best Performance mode. ESS9311 – is the industry’s first low-noise, low-dropout regulator designed specifically for high-performance audio systems. It is optimized for high resolution audio thanks to its revolutionary dual regulator architecture. This innovative architecture contains series-voltage and shunt-voltage elements, eliminating the need for output decoupling capacitors – an industry first in audio system design.

The ESS9311 provides the extremely low-noise outputs that are necessary for driving the reference inputs of audio converters and also offers significant value-add for audio system designers for the Pro-Ject PJ65186400 Pre Box S2 Digital. Organic polymer capacitors are used in critical positions like the analogue power supply. These capacitors are very low thermal drift which result in consistent playback performance. Precision Thin Film MELF resistors – such resistors has very low voltage coeficient. It results in perfect sounds without impurities. 16-core XMOS USB chip for asynchronous USB data transfer and MQA unfolding. Also, gold plated four layer PCB with extra shielding for achieving optimal audio performance. Full colour OLED display for indication of volume level, selected input, sample rate and lastly, type of input digital signal.

Synchronization of all oscillators

This extremely important feature is almost always overseen. Imagine an orchestra without a drummer or a conductor. Every musician plays in his own rhythm and tempo. The result is chaos which nobody can listen to. The same applies to oscillators in a DAC. There are a lot of oscillators with different frequencies and they also start to talk chaotically – what could the result be? The complete opposite happens when all the oscillators are perfectly synchronized and work like an orchestra with the perfect conductor. This results in low jitter, minimizing of interference and it is very important for good sound.

Double filtering for a noise free USB input

One of the major problems for USB DACs is the transmission of unwanted noise coming through the USB output. A lot of research of Pro-Ject PJ65186400 Pre Box S2 Digital went into how to make this noisy connection more quiet. However , after a lot of headscratching trial and error we found the solution to lie in active and passive filtering of the output
