本日下午在內湖的極品音響(Orpheus 台灣代理商), Mr. Carreira Sergio 為網友們說明了Orpheus 的一些設計理念, 及網站中的最新未曝光的產品(Digital Audio dock, DAD)的少許機密 8) 今天非常感謝 Drunkenlife 兄的全力相助採訪 (blush) :* :P
先來張年輕的帥哥照 .... 接受採訪時專注的神情 ~~

To be continued ....
Sergio很健談，並不是宅男型的工程師，
首先請他先談談自己的背景以便我們理解該請教他那方面的問題，
他提到自己是科班出身，電子軟硬體都學，而且數位與類比都在行，實在相當不容易；
這趟來台灣的行程是對代理商進行技術訓練，若看過Orpheus產品的使用手冊就會發現它們的產品有很大的彈性，
往往有二、三組輸出可以個別調整gain，以便搭配多擴大機或多聲道系統，因此遠道跑這趟親身解說。

此外也為了新產品Vanguard Digital Audio Dock
來看看這個dock的輸出入介面
實在是複雜的誇張哪～除了WiFi以及AirPlay之外大概所有常用的介面全都上了～引用:
Inputs
Word clock IN / OUT (44.1KHz/48KHz/96KHz/192KHz)
Firewire multichannel: 8 Channels 24Bits @ 192kHz
USB 2.0 multichannel: 8 Channels 24Bits @ 192kHz
LAN/Ethernet: UPnP Compliant, Configurable WebRadio
iPod and iPhone Dock.
Bluetooth 2.1+ EDR A2DP (iPhone compliant)
USB Flash Direct playback
HDMI not HDCP Compliant
Optical ADAT: Up to 8 Channels 24Bits @ 48kHz
TOSlink: 1 Channel 24Bits @ 192kHz
Analog Line IN
Digital Outputs
4 x SPDIF channels
1 x ADAT
Analog Input
1 x Line In over jack
Analog Output
Headphone
1 x Line Out over jack
這哪裡是個dock而已？根本就是個universal hub了～
我想單是找到這所有的solution再兜起來就不知要花多少時間了...
他們還花了許多時間在弄出個簡單的操作介面，你可以想想看八聲道的USB該怎麼設定到4個S/PDIF或1個ADAT？
其中還提到為何有了USB，卻還再加上Firewire，二者都能在PC上找到啊？何不單選USB？
這當然還是為了聲音考量，asynchronous USB solution太難找了，不得已，還是用上adaptive USB，
但另外提供用asynchronous的Firewire，給追求高音質的消費者個選擇。
還有個重點，HDMI，眼前提供HDMI介面的HiFi stereo產品應該還非常少吧？
Orpheus非常看好HDMI的應用，不只stereo，甚至多聲道產品未來都有可能推出，
不過，一切還在討論之中，尚未定案...
Orpheus可不會只是隨便拿stereo擴大機兜上幾個小功率電路就推出多聲道擴大機啊...
各位若是有啥意見，請盡管提出，以供Orpheus參考。

再來請他談談Heritage DAC MP2中用到的獨門秘技，降低jitter的ANAGRAM模組，
很可惜，他說，無可奉告！
啊？為何？
因為那是ANAGRAM的技術，雖然說Orpheus是ANAGRAM的子公司，而且有相關的文件，但實際上內部怎麼做的，Mr. Sergio也不清楚...
只確定一點，那是DSP技術，模組內部主要是跑軟體做的。
有趣的是，ANAGRAM已經被另一家公司買下，因此Orpheus得向那家公司買這模組，
還真是錯縱複雜的交互關係啊...
再來談談擴大機，
Mr. Sergio提到Orpheus的每隻擴大機都是獨立全新的設計，而非只是照樣放大或縮小功率那般手法，
使用的零件也都必須仔細測量過，不是單純看規格而已，
甚至功率輸出級用BJT或MOSFET，Orpheus也不會完全堅持只用其一，
就看開出來的規格如何，再據以決定。
至於這規格嘛，可不是簡單的一句350瓦就行了，
工程師要問的問題會是，350瓦，失真多少？
也就是設計規格囉～
Orpheus的要求一向是全功率的80%，仍舊必須維持THD（總諧波失真）在0.01%！
夠狠吧？
對這數字沒概念？
350瓦的80%就是280瓦，這功率可以發出多大的音量？
若是你用的是超低靈敏度只有84dB的喇叭，而且你坐在3公尺外，
那280瓦可以發出近99dB的音壓！這足夠讓你想奪門而逃了...車水馬龍的道路邊也不過是88dB而已..
而這時，擴大機的總諧波失真仍舊低達0.01%...
你的喇叭的失真這時該超過10%了吧...
最後Mr. Sergio提到有啥技術問題，他很樂意回答，請大家不吝提出，
我想用家應該會有一堆問題想問，Orpheus的產品彈性實在很大，設定可不是簡單事..
至於Orpheus的愛用者，若有啥對他家產品未來的期望，可以請kib轉達給Mr. Fabien，
又，Sergio也是個Mac愛用者！非不得已不用Windows
我也是...

Orpheus Vanguard Digital Audio Dock
With the convergence of entertainment systems, we at Team Orpheus came to realise that the future of not only audio but also entertainment technology is in all in one solutions, the main concept of which is integration. Since 2010 Team Orpheus has been developing a Digital Audio Dock (DAD). It has been created as an all encompassing solution for digital audio playback. Its aim is to allow any digital audio source to be compatible with S/PDIF and ADAT Lightpipe formats, which are protocols for transferring widely used digital audio data.
The minimalistic avant garde design, designed for simplistic eye pleasing perfection, can trick the beholder, as the Vanguard DAD houses the power and potency unrivalled by any Digital Audio Dock.
Connecting your computer to your DAD has never been simpler as a large number of connection ports are provided in the DAD for complete digital compatibility. The supported digital protocols are USB 2.0, FireWire 400, Bluetooth AD2P, LAN and USB Flash. The DAD is able to work in multichannel mode with the USB, FireWire and ADAT modules.
The DAD also comes with licensed iPod and iPhone compatibility, in a dock which not only enables playback of your iPod/iPhone content but also the recharging of the devices. The most significant aspect of the iPod dock is that it enables better quality data transfer than a normal analog jack, by reading the numerical iPod transcript, the result of which is true representation of the audio. The features don't end here: for ease of use, it is possible to control your mobile device with the DAD itself.
To make listening to music directly from the internet possible, a web interface has been included, whereby it is possible for the user to configure the their desired URL and gain direct access to and high quality playback for their preferred web hosted audio content.
Exterior
The front panel is equipped with 9 LEDs to indicate the input selection, and two switches with which to control the input source. There is also a switch for the selection of the output sample rate which ranges from 44.1KHz to 192KHz.
To minimise jitter, the clocking information is displayed with two LEDs, to indicate whether the Phase Loop Lock (PLL) is locked and whether the system is clocked with an external signal.
The use of headphones has been made as convenient as possible by placing a headphone jack on the front panel accompanied with a volume control.
The DAD is also equipped with a USB port, located on the front panel, to enable the playback from USB flash keys and an iPod/iPhone dock on the top.
Controlling the DAD has been made as easy as possible with the controls on the front panel, or alternatively with the remote control which is capable of controlling the entire system.
