Pre Box S2 Digital - a performance revolution in a small package!  


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 pack-age. 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 pro-prietary 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 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 seven digital filters the sound can be shaped precisely to the listeners lik-ing. 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!

FAQ - Hints for using Pre Box S2 Digital  


Q: Does the device support Windows 10?  

A: The device is fully compatible with Windows 10. It may be necessary to reinstall latest drivers after updating from Windows 7/8/8.1 to Windows 10.  


Q: Does a driver exist for Mac OSX- or Linux-Systems?  

A: You do not need a driver. The driver is already integrated in the operating system.  


Q: Pre Box S2 Digital will not be recognized by Mac OSX and is not available under Audio. What can I do?  

A: Turn off your Computer and press at start alt+cmd+p+r until another starting sound appears. With this command the USB bus will be reset and the USB Box will be recognized new.  


Q: Pre Box S2 Digital will not be recognized by Mac OSX (El Capitan/Sierra) or does not output sound.  

A: There are many forum reports about that issue. It is a widely spread error affecting a wide array of USB DACs, unfortunately there is no current fix for this problem, since it lies in the Core Audio of Apple's OSX. We advice not to use our USB DACs with OSX El Capitan.  


Q: How do I determine if Pre Box S2 Digital is playing MQA files?  

A: Pre Box S2 Digital will show the MQA logo and a blue dot on the display's top right corner once an MQA file has been successfully passed on to it.  


Q: Does the device support MQA over the coaxial or optical input?  

A: No, in order to enable MQA playback via S/PDIF a hardware change would be necessary, this would cause the price to go much higher. MQA hardware decoding is only possible via the asynchronuous USB input of Pre Box S2 Digital.
