後製作Studio最佳選擇-RME Fireface800

OVERVIEW	Top

經過超過兩年的研發， RME隆重為您推出Fireface 800， 全世界弁鈳戔j悍的Firewire錄音介面。 高達56 channels的錄放音能力， 可達192 kHz 的曲樣頻率，FireWire 800 集合high-end, high performance 以及 high speed 三High的卓越性能於一身。
  

Fireface 800 結合了旗下產品最新以及最為稱釭漣瑋N，以及最快速的FireWire技術。 取自ADI-8 converters, 的類比數位轉換技術，取自 QuadMic 與 OctaMic的麥克風前級放大技術，取自 Hammerfall DSP series 的TotalMix 技術，以及長年來備受信賴以及穩定的驅動程式研發，乃至完全支援 DIGICheck - 一切都取自最好中的最好而成。 Fireface 800 提供所有錄音介面中最優良的instrument input ，高必v的耳機輸出以及達到119 dBA的S/N比 - 都來自 RME!!

類比 輸入/輸出部分	Top

RME知名的 Multiface 是Fireface 800設計的基礎來源， 8組 平橫式的輸入輸出端子，利用軟體來控制切換增益的數值 (-10 dBV, +4 dBu, HiGain)，當然在類比的情形下我們都了解，要保障最高的動態以及最高的真實度 。除了麥克風前級以及耳機輸出需要用人為控制，所有的設定都可以利用軟體控制，採用最新的A/D 以及 D/A 轉換器晶片，所有的輸入輸出端子都可以達到192 kHz的取樣頻率以及119 dBA 的播放動態範圍- 即使是耳機輸出也是!

前面板的耳機輸出 採用高必v設計，並不是只能提供低組抗耳機高音量的輸出，而是提供9/10軌道的播放輸出重現， 因此耳機輸出能直接使用 ASIO Direct Monitoring(ASIO直接監聽)。

在前面板，Fireface 800 具備 4 組平衡式的麥克風輸入，都是class-A等級，各自具備獨立的48 V幻象電源供電以及獨立的 XLR/TRS 輸入端子， 其中Linein部分也是可以調整Gain的，範圍高達50 dB!  其中兩組Mic輸入是一直都對到第9以及第10軌， 其餘兩組則可以同時使用，或是指向背板的第7/8的輸入軌。

LET'S ROCK!	Top

FireFace 800's Hi-Z instrument input offers an unprecedented fidelity and flexibility for the use of guitar and bass. A soft-limiter, which has been tuned especially for musical instruments, efficiently prevents overloads of the A/D-converter. The limiter does not work without distortion, it intentionally creates harmonic distortion. Due to a soft transition and deliberate creation of harmonics, the input signal is compressed steplessly according to taste, or the limiter can be used as a distortion with tube sound. A Drive circuit, which can be activated in addition, delivers broad guitar distortion. The Speaker Emulation filter, which can also be switched on separately, takes low- and high-frequency disturbances away and guarantees an optimal basic sound even when recording directly into the computer, or when monitoring through a mixing console. Signals from guitar or bass are not being alienated in this case, but pre-conditioned for later processing in the DAW, so that the known amplifier plug-ins can make the most out of the sound.

DIGITAL I/Os	Top

Two ADAT optical I/Os allow for a connection and insertion of effect devices, mixing consoles or external converters. Of course, these 16 channels are available simultaneously with the analog channels. Using two additional ADI-8 DS, you'll get 26 analog inputs and outputs, which remain still 18 at 96 kHz. The coaxial SPDIF I/O works up to 192 kHz, so that there are still 10 analog in- and outputs at the highest sample rate, plus two digital ones. SPDIF optical, alternatively provided via the second ADAT port, also operates up to 192 kHz - another RME-only feature.

FEATURES	Top

All inputs and outputs can be used at the same time*!. E. g., the instrument input can be used either instead of the line input on the back, ortogether with it. Even the TRS jack and the XLR socket of the microphone inputs can be used simultaneously. In this way, up to 35 signal sources can be connected to the Fireface 800 and recorded onto 28 separate tracks!

Thanks to the DSP-based TotalMix mixer, known from the Hammerfall DSP series, all inputs and outputs can be freely mixed, distributed and routed. Up to 14 completely independent stereo submixes are possible. Each of the mixer's output channels, that is every single submix channel, can be recorded directly, without the need of external cable loops.

Thanks to an internal flash memory, all settings including TotalMix are recalled during boot. After making all desired settings, the device worksstand-alone even without computer as a submixer, A/D and D/A-converter, headphone mixer, format converter, instrument or microphone pre-amplifier, monitoring mixer and much more.

The Fireface 800 is equipped with SteadyClock™, RME's unique sync and clock technology. With this, the device becomes a sync reference for the whole studio. SteadyClock refreshes clock signals, removes jitter, and takes permanent care of optimal conversion quality, thus guarantees a sensational sound quality, completely independent from the reference clock's quality.

SteadyClock allows the Fireface 800 to control the sample rate freely on its own. The Settings dialog includes a direct choice of the video and audio world's most often used sample rates. Additionally, two faders can be used to set the sample rate freely and in real-time, within the range of +/- 4% and +/- 0.4%.

Via an insert slot on the back, a Time Code Option (TCO) for synchronizing to LTC and video can be added. Thanks to SteadyClock, the Fireface 800 does not only extract absolute positions, but also a very clean low-jitter word clock.

Fireface 800 uses RME's own FireWire techology, heavily optimized for audio purposes. Lowest overhead, special hardware adaptations and a new low latency buffer concept enable a performance and compatibility which has been thought of as impossible until now - at latencies of only one millisecond.

The Fireface 800 has a second port for hub functionality, bi-lingual mode for full FireWire 400 compatibility, and an additional FireWire 400 port. Several Fireface 800 can be used in parallel and at the same time on one FireWire port without any problem.
