Ethernet and WiFi connectivity Video Awards “Pro-Ject’s Pre Box S2 Digital offers a wealth of audiophile tweakery but its emphasis on USB ties it primarily – but not exclusively – to desktop and laptop PCs. On the other hand, USB hook-up means the S2 is still a portable option for laptop users, and it doesn’t need a battery. For the price, its sound performance is impeccable, combining clarity and precision with an attractive warmth and impressive sense of space.” Click here to read the full review Stream Box S2 Ultra Audio Formats PCM 32bit/352.8kHz, DSD256 Internet Radio Shoutcast Streaming Services TIDAL, Spotify Supported data protocols RAAT, Shairport, DLNA Multi-room Up to six devices Inputs 2 x USB A Micro USB B (PC-Detox) Network (Ethernet, WiFi) Outputs Audio optimized USB A HDMI (video) Controllable via App, Web Browser, Roon Weight 375 g (without power supply) Dimensions (WxHxD) 105 x 37 x 105 mm Pre Box S2 Digital Specs DAC: 2x ESS9038Q2M 32-bit PCM 768kHz / DSD512 Digital Inputs: 1x Coax (S/PDIF) 2x Optical (TOSlink) 1x USB B Headphone Amp Chip: ESS9062 Sampling Rates: 32kHz 44.1kHz 48kHz 88.2kHz 96kHz 176.2kHz 192kHz 352.8kHz 384kHz 768kHz DSD Support: DSD64 DSD128 DSD256 DSD512 MQA Support: Full MQA Unfolding by Hardware Filter Settings: 7x Selectable Frequency Response: 20Hz – 20kHz THD: 0.0003% Analogue Outputs: 1x Headphone (6.35mm Jack) 1x Variable Out (RCA) Dynamic Range: 124dBA Output Voltage: 2.05 Veff Power Consumption: 5V.
