This Sony MDR-DS5100 Advanced Headphone System with DTS Digital Surround Sound incorporates Sony VPT Virtual Phones Technology with advanced level 125MIPS (125 million instructions per second) Logic 3D Processor for richer and more natural "live" sound quality, with "weightier" more substantial bass sounds to enhance the sense of live presence. Built in Dolby Digital, Dolby Surround, and DTS Virtual 5.1 Decoders reproduce all popular surround sound systems including state of the art 5.1 channel sound as well as Digital Theater Systems surround sound. Decode-Mode Indicator on Front Panel visually indicates when the system is in Dolby Digital, Dolby Surround, or DTS mode, and provides a stylized representation of the virtual speaker placement relative to the listener, for each mode. Built in Dolby Pro Logic Decoder unlocks the Surround Sound tracks often included in VHS Hi-Fi, stereo TV, and other traditional sources to provide the maximum "live" entertainment experience available. Optical Digital Input allows use with Dolby Digital and PCM audio. Gold Plated Analog Input is provided for noise-free Dolby stereo and pure stereo sources. Fifth Order Delta/Sigma A/D Converter uses 64X oversampling for high precision. Multi-Level Delta/Sigma D/A Converter achieves 18 bit resolution. SILMIC Electrolytic Capacitors are provided in the analog stage, for more natural sound. 35µm Copper Board Traces are twice as thick as conventional designs, for higher conductivity.
