NuForce DAC-80 ( DAC, Pre amplifier)
DAC-80 có độ phân giải cao 24bits/192kHz, gồm có đến 4 đường vào tín hiệu digital, 1 USB, 1 Toslink, 2 Coxial, với nhiễu tín hiệu (jitter) thấp, xuất âm thanh sạch.
DAC-80 với Pre Amp (amplifier) cho tiếng trong, chính xác, xuất ra đường analog RCA.
DAC-80 là giải pháp khá tối ưu khi muốn nghe nhạc từ nguồn máy tính đến các hệ thống Loa Hi Fi-Hi End. DAC-80 là DAC-Pre Amp để nối đến thằng Power Amplifier (hoặc Integrated Amplifier ) và cặp Loa Hifi của bạn. Nó hoàn toàn ngon lành bởi thiết kế tinh tế, hiện đại, khỏe với vỏ bằng hợp kim nhôm.
Một hệ thống phối ghép tham khảo tại chỗ chúng tôi sử dụng DAC 80 như sau : Nuforce DAC 80 (DAC,Pre Amp) --> STA 100 ( Power Amp) --> Amphion Argon 3 ( Passive Speaker ).

The NuForce DAC-80 is a class-leading digital-to-analog converter
offering one USB and three S/PDIF inputs. The DAC-80 accepts up to four digital input sources and features a precision digital volume control, a high-resolution analog RCA output stage, and a convenient wireless remote. Note: Nuforce USB Audio devices are designed to work with x86 architecture. Tablet devices running Windows 8 (RT) are not supported. The DAC-80 incorporates several NuForce innovations: |
Low Jitter The DAC-80’s digital input stage operates in an asynchronous mode independent of any timing errors associated with the incoming digital audio stream. The input stage synchronizes the data to an internally referenced timing signal generated by an exceptionally stable circuit. The re-clocking circuit’s accuracy is such that any negative timing errors (jitter) are reduced to near theoretical limits. Precision Volume Control A digital 32-bit volume control offers precise channel tracking. Unlike more common digital volume controls operating at 24 or 16-bits, the 32-bit dynamic range of the DAC-80's volume control avoids any loss of low-level resolution. Transparent Preamp The analog preamp stage is a "minimalist" design that offers a signal path that approaches a "straight wire with gain" level of performance. Combined with top quality parts and a full 4.0Vrms signal level at the RCA outputs, the preamp section of the DAC-80 ensures that only the purest of analog music signals will ever be presented to your preamplifier. No Up-sampling A 24-bit, 192kHz DAC stage accurately converts digital audio data back to an analog signal at its native sampling rate. No up-sampling or other questionable data manipulation is ever employed. Note: For Async USB Audio, please refer to the Async USB Audio FAQ and Setup Guide. The following plots showed exceptionl performance of DAC-80. Please refer to larger images of the measurement plot in the image gallery above.

The DAC-80 THD+N measurement is exceptional. The slope of the plotted line is linear, indicating the absence of non-linear components added by the DAC. The standard THD+N measurement as commonly referenced in the audio industry is indicated at the –0 dB point (at the far right of the graph). As we can see, THD+N is less than .005% – extremely good THD+N performance for any audio component.
*During initial turn on, there may be a brief 'noisy music' at low volume for 2 seconds if the CD/Track is being played while the DAC80 is being power-up and setting up itself. |
