hdiii Postat Ianuarie 6, 2015 Share Postat Ianuarie 6, 2015 DAC EMOTIVA DC-1 Stealth Un DAC semi professionist. Sunet curat, neutru. AD1955, USB si XLR: astea fac tot deliciul. Support for all popular sample rates. The Stealth DC-1 supports 44.1k, 48k, 88.2k, 96k, 176.4k, and 192k sample rates, at both 16 bit and 24 bit word lengths, from ALL of its inputs - including USB. A full complement of digital inputs. The Stealth DC-1 has a full selection of digital inputs, including: AES/EBU (XLR), Toslink (optical), Coax S/PDIF (RCA), BNC S/PDIF, and high performance USB. Analog inputs. The Stealth DC-1 has one unbalanced stereo analog input, which can be used to attach legacy gear - like the output of a phono preamp or tuner. High performance Asynchronous USB. The C-Media CM-6631A high performance USB interface chip provides enhanced jitter immunity and excellent audio performance. Advanced ASRC (asynchronous sample rate converter) reduces jitter, yet preserves original sample rate. The advanced ASRC implementation in the DC-1 eliminates jitter on all inputs (not just USB), yet lets you hear your music unaltered - at its original sample rate. Dual fully differential AD1955 DACs. The Stealth DC-1 is fully differential, and uses dual independent Analog Devices AD1955 precision multi-bit delta-sigma DACs, each operated in their highest-quality internal differential monaural mode, for exceptionally low noise and distortion. Precision LM4562 op amps. The DC-1 uses all high quality LM4562 op amps in the output signal path for excellent audio performance. Dual Muses 72320 digitally controlled analog ladder volume control chips. The volume for each fully differential channel is controlled by a separate Muses 72320 precision volume control IC, operated in our unique and proprietary dual gain control mode (by simultaneously controlling both signal level and the gain of the gain stage itself, this technique optimizes the signal handling at various gain levels to achieve the absolute best noise and distortion performance at any given setting). Galvanically isolated digital inputs. The AES/EBU and electrical S/PDIF inputs on the DC-1 are all transformer isolated to ensure signal purity and stability and help eliminate signal ground noise. Intelligent headphone outputs. The headphone outputs on the DC-1 are driven by independent high current, low distortion BUF634 buffers - driven by our proprietary input buffer circuitry; their low output impedance ensures accurate frequency response and low distortion into real world headphone loads. Output levels for main and headphone outputs are independently controlled and retained in memory. Citează Link spre comentariu Distribuie pe alte site-uri More sharing options...
