Inputs and Outputs
Analoge I/Os
: Eight balanced line inputs and outputs with software controlled switching of the reference levels (-10 dBV, +4 dBu, HiGain), of course realized discretely in the analog
domain, guarantee highest dynamic range and highest fidelity. Apart from the levels of the microphone pre-amps and the headphone outputs, all device settings are software
controlled. Equipped with the latest A/D and D/A converter chips, all I/Os operate up to 192 kHz and reach 119 dBA dynamic range on playback - even the headphone output (playback
channels 9/10), whose high power technology delivers high volume even with low-impedance headphones.
On the front side, the Fireface 800 has 4 discrete balanced microphone inputs with class-A stage, separate activation of 48 V phantom power and separate XLR/TRS inputs, where the
latter can also be used as additional Line inputs. Two of the four mic inputs are permanently available as channels 9 and 10, the other two can be used together with or alternatively
to the inputs 7/8 on the back.
The FireFace 800’s Hi-Z instrument input offers a soft-limiter, which has been tuned especially for musical instruments. 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 for distortion with tube sound. Activate the Drive circuit too for 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.
Digital I/Os
: Two ADAT optical I/Os allow for a connection and insertion of effects devices, mixing consoles or external converters. Of course, these 16 channels are available
simultaneously with the analog channels. Using two additional ADI-8 DS, there are 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.
Features
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, or together with it. Even the TRS jack and the
XLR socket of the microphone inputs can be used simultaneously. 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. And there’s
more: TotalMix can be MIDI remote controlled with any Mackie Control compatible controller.
All settings including TotalMix are recalled during boot via flash memory. After making all desired settings, the device works stand-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(TM), 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.
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.
* In Quad Speed mode (176.4 and 192 kHz), both ADAT I/Os are deactivated
