Audio Byte 推出 Black Dragon

DSD Digital preamplifier with discrete headphone amplifier



Black DRAGON - DSD Digital preamplifier

Which d/a converter? Which preamp? Which headphone amplifier? These are questions that popped up many times in our "audio" life. "Integration" is what spells our friendly dragon as a response. One box instead of three? Let's see why.

Black DRAGON 內含 DAC、前級和耳機擴大機，將三個功能都容納在 Black DRAGON 中。


The unique digital processing architecture makes the Black Dragon pretty unique at this price level. Instead of using off-the shelf chips for internal circuitry, dedicated hardware units are built inside a FPGA-chip to form together a powerful and custom front-end to the dac chips. This include digital receivers sampling input signals at 500 MHz , the clock system able to reduce timing errors to sub-picosecond level, the powerful digital filter made with 15 DSPs, the user interface.

Black DRAGON 的數位架構相當特別，使用一個 FPGA 和特製的 DAC 晶片，在輸入端的訊號擷取採樣可達到 500 MHz，內部擁有自己的主時鐘系統，強力的數位濾波使用 15 個 DSP。


Femtovox clock system allows jitter reduction as low as 300 fS right before entering dacs. For a detailed explanation about this technology please consult the Black Dragon white paper.

Femtovox 的時鐘系統可在訊號進入 DAC 之前讓震動低於 300 fs。


The custom hybrid-phase digital filter is a high-performance upsampling block for conditioning the incoming signals. It is especially effective on standard resolution digital signals, like 44.1/48 KHz. With a large number of taps and a carefully adjusted response, the extension and atmosphere of the recordings are virtually enhanced prior to conversion. The filter can be enabled or disabled from the menu interface. For filter detailed performance consult the technology paper.

內含一個特製的混合相位數位濾波器，是一個高性能的升頻模組，對於標準的 44.1 kHz 和 48 kHz 特別有效。用戶可在選單中開啟或關閉。


True dual balanced conversion (2 x AK4396) is a perfect complement to the digital input stage. Each dac chip is processing one channel in fully balanced mode which leads to better analog performance and noise rejection.

使用 2 x AK4396 的 DAC 晶片，達到完整的平衡轉換。


Driverless USB input for Mac and Linux is natively capable of resolutions of 24bit/384 KHz sample rate and DSD64 /128. For Windows, ASIO and WASAPI/KS drivers are available under the download section. Asynchronous operation means that the dac dictates the USB audio transfers after its master clock and not the PC, resulting in minimal jitter.

USB 輸入以 MAC 和 LINUX 可達到 24bit/384 kHz，Windows, ASIO and WASAPI/KS 也已經有驅動程式可供下載使用，另外 DAC 會主導時鐘部分，而非使用電腦中的時鐘。


Fully discrete , true balanced, zero-feedback class A output stage / headphone amplifier section will drive without problems from low to high impedance headphones.

完全平衡的零反饋 A 類耳機擴大機，對於任何高低阻抗的耳機皆無問題。


The low noise LNS (linear power supply) - all power supplies inside are linear type. There are a total of 11 linear stabiliser IC's, 8 of them are low noise. The total filtering capacity exceeds 50.000 uF. The power supply is serviced by 2 separate toroidal transformers.

低噪聲的線性電源，所有電源都是線性，內有 11 組線性穩定 IC，其中 8 個為低噪聲，濾波電容超過 50.000 uF，由兩個獨立環形變壓器供應。


User convenience – there are 5 digital inputs available: USB, spdif, aes/ebu, i2s and optical toslink. Balanced, single ended and headphone outputs are present. The large display is easily readable from the listening point.

共有五個數位輸入端子，USB、spdif、aes/ebu、i2s 和 optical toslink。


Easy firmware upgrade – the Black Dragon can be updated in the field by easily playing a special update track via the USB input. Any firmware updates will be available under the download section.

Black Dragon 可使用 USB 輕鬆升級。
