1. We have specially developed a fully shielded toroidal transformer with three separate secondary windings Five regulated power supplies are employed three analog and two digital This ensures the analog circuitry has maximum isolation from any digital power supply artefacts and noise 15 Block Diagram USB Connectivity Plug and Play BNC Digital Input Connector Up Sampling 24 bit Resolution 16 PRERIRE AUX E ANALOG DAC STAGE O P Divider ASRC Selector Divider The SXD2 is fully compliant with USB 1 1 specification and utilises Full Speed 12Mbps transceivers The bandwidth offered by Full Speed USB is more than sufficient to stream digital audio Designed to bypass the inherently flawed soundcards internal to computers the SXD2 offers plug and play convenience when connected via the USB port RCA connectors are inherently disadvantaged for use with the high frequency 1 4MHz 2 8MHz signals associated with 44 1kHz 16 bit digital audio Design limitations mean RCA connectors can never achieve a characteristic impedance of 75Q resulting in reflections and signal loss due to impedance mismatch In contrast BNC connectors are purposely designed to carry high frequency signals up to 2GHz for 75Q therefore overcome the problems exhibited by RCA connectors The SXD2 automatically up samples the digital signal 4x the input sample frequency up to2. and function blend together in perfect harmony This surely is the essence of true minimalist utilisation Minimalism in a Wider Context John Pawson writes Clearly simplicity has dimensions to it that go beyond the purely aesthetic it can be seen as the reflection of some innate inner quality or the pursuit of philosophical or literary insight into the nature of harmony reason and truth 6 Construction Circuit Topology The Power Supply Separate Analog and Digital Supplies PRERE NUX A Special Design Features The beautifully styled curving front panel is milled from solid 6 0mm 0 2 thick aluminium extrusion and finished in a satin chrome electroplate The front panel also features the PERREAUX logo machined into the solid aluminium The chassis and cover are both manufactured from heavy gauge steel No cover fixing screws are visible The Silhouette SXD2 is stylish yet functional and exhibits typical hallmarks of the Perreaux brand AC Input Analog Filter l V Converter Analog Stage Power Supply Microcontroller E Digital Stage The SXD2 has an internal power supply These designs are invariably more sophisticated than those featuring external plug in power packs Special attention must be paid to shielding transformer design capacitance and earthing
