User's Guide Fireface 800 © RME 15 User's Guide Fireface 800 Installation and Operation - Windows.
16 User's Guide Fireface 800 © RME 9. Hardware Installation Desktop Computer • Use the power cord to connect the Fi reface with any suitable power outlet.
User's Guide Fireface 800 © RME 17 Possible reasons why a Fireface is not found automatically: • The FireWire port is not active in the system (drivers of the FireWire PCI or CardBus card have not been installed) • The FireWire cable is not, or not correctly inserted into the socket • No power.
18 User's Guide Fireface 800 © RME When the update fails (status: failure), the unit' s second BIOS will be used from the next cold boot on (Secure BIOS Technology). Therefore the unit stays fully functional. The flash process should then be tried again on a different computer.
User's Guide Fireface 800 © RME 19 Buffer Size The setting Buffer Size determines the latency between incoming and outgoing ASIO and WDM data, as well as affecting syst em stability (see chapter 13/14). Bandw idth Allows to reduce the amount of bandwidth us ed on the FireWire bus.
20 User's Guide Fireface 800 © RME Input Status Indicates for each input (Word, optical, SPDIF coax ., TCO) whether there is a valid signal (Lock, No Lock), or if there is a valid and synchronous signal (Sync). The second row shows the sam- ple frequency measured by the hardware.
User's Guide Fireface 800 © RME 21 11.3 Settings Dialog – Gain Inputs Input selection for the channels 1, 7 and 8. Channel 1 can be the front instrument input, or the rear TRS jack, or both simultaneously. Channel 7/8 can be the front microphone input, or the rear TRS jack, or both simultaneously.
22 User's Guide Fireface 800 © RME 11.4 Clock Modes - Synchronization In the digital world, all devices must be either ‘Master’ (clock source) or ‘Slave’ synchronized to a master. Whenever several devices are linked wi thin a system, there must always be a single master clock.
User's Guide Fireface 800 © RME 23 At 88.2 or 96 kHz: If the ADAT input has been selected in Pref Sync Ref , the sample frequency shown in the SPDIF Freq. field differs from the one shown in AutoSync Ref . The unit automati- cally switches to S/MUX mode here, because ADAT optical inputs and outputs are only speci- fied up to 48 kHz.
24 User's Guide Fireface 800 © RME 12. Operation and Usage 12.1 Playback The Fireface 800 can play back audio data in s upported formats only (sample rate, bit resolu- tion). Otherwise an error message appears (for example at 22 kHz and 8 bit). In the audio application being used, Fireface must be selected as output device.
User's Guide Fireface 800 © RME 25 12.2 DVD-Playback (AC-3/DTS) AC-3 / DTS When using popular DVD software players like WinDVD and PowerDVD , their audio data stream can be sent to any AC-3/DTS capable re ceiver using the Fireface's SPDIF output.
26 User's Guide Fireface 800 © RME 12.3 Notes on WDM The driver offers a WDM streaming device per stereo pair, like Fireface ADAT 1 (1+2) . WDM streaming is Microsoft's current driver and audio system, directly embedded into the operating system.

28 User's Guide Fireface 800 © RME 12.6 Digital Recording Unlike analog soundcards which produce empty wave files (or noise) when no input signal is present, digital interfaces always need a valid input signal to start recording.
User's Guide Fireface 800 © RME 29 13. Operation under ASIO 13.1 General Start the ASIO software and select ASIO Fireface as the audio I/O device. The 'ASIO system control' button opens the Fireface's Settings dialog (see chapter 11 / 22, Configuration).
30 User's Guide Fireface 800 © RME 13.3 Known Problems If a computer does not provide sufficient CPU-pow er and/or sufficient PCI-bus transfer rates, then drop outs, crackling and noise will appear. Raisi ng the buffer size in the Settings dialog of the Fireface 800 helps in most cases.
User's Guide Fireface 800 © RME 31 The driver takes care of the numbering of all Fi refaces, so that it doesn't change. The unit with the lowest serial number is always 'Fireface (1)'. Please note: • If the Fireface (1) is switched off, Fireface (2 ) logically turns to the first and only Fireface.
32 User's Guide Fireface 800 © RME 16. Hotline – Troubleshooting 16.1 General The newest information can always be found on our website www.rme-audio.com , section FAQ, Latest Additions.

User's Guide Fireface 800 © RME 39 Inputs Input selection for the channels 1, 7 and 8. Channel 1 can be the front instrument input, or the rear TRS jack, or both simultaneously. Channel 7/8 can be the front microphone input, or the rear TRS jack, or both simultaneously.
40 User's Guide Fireface 800 © RME Bandw idth Limit Allows to reduce the amount of bandwidth us ed on the FireWire bus. See chapter 19.4. All channels (default) activates all 28 input and output channels. Analog + SPDIF + ADAT1 disables channels 21–28 (ADAT2).
User's Guide Fireface 800 © RME 41 19.2 Settings dialog - DDS Usually soundcards and audio interfaces generate their internal clock (master mode) by a quartz. Therefore the internal clock can be set to 44.1 kHz or 48 kHz, but not to a value in be- tween.
42 User's Guide Fireface 800 © RME Application examples DDS allows for a simultaneous change of speed and tune during record and playback. From alignment to other sources up to creat ive effects – everything is possible.. DDS allows to intentionally de-tune the complete DAW.
User's Guide Fireface 800 © RME 43 If several digital devices are to be used simult aneously in a system, they not only have to oper- ate with the same sample frequency but also be synchronous with each other.
44 User's Guide Fireface 800 © RME 20. Mac OS X FAQ 20.1 Round about Driver Installation The driver with the file suffix zip provided by RME is a compressed archive. Zip is directly sup- ported by OS X, a double click on the file is all one needs to do.
User's Guide Fireface 800 © RME 45 20.5 Supported Sample Rates RME's Mac OS X driver supports all sampling frequencies provided by the hardware. This in- cludes 32 kHz and 64 kHz , and even 96 kHz and 192 kHz . But not every software will suppor t all the hardware's sample rates.
46 User's Guide Fireface 800 © RME 21. Using more than one Fireface OS X supports the usage of more than one audio device within an audio software. This is done via the Core Audio function Aggregate Devices , which allows to combine several devices into one.

50 User's Guide Fireface 800 © RME 24. Stand-alone Operation The Fireface 800 has an internal memory to per manently store all conf iguration data. These are: Settings dialog Sample rate, clock mode Master/Slave, confi guration of the channels and the digital I/Os.
User's Guide Fireface 800 © RME 51 25. Analog Inputs 25.1 Line Rear The Fireface has eight balanced Line inputs as 1/4" TRS jacks on the back of the unit.
52 User's Guide Fireface 800 © RME 25.3 Instrument The instrument input of the Fireface 800 has been optimized especially for guitar and bass. A soft clipping function limits the level from –10 dB FS on, and offers tube-like distortion at full overload.
User's Guide Fireface 800 © RME 53 26. Analog Outputs 26.1 Line The eight short circuit protected, low impedance line outputs are available as 1/4" TRS jacks on the back of the unit. The electronic output stage is built in a servo balanced design which han- dles unbalanced (mono jacks) and balanced (stereo jacks) correctly.
54 User's Guide Fireface 800 © RME 27. Digital Connections 27.1 ADAT The ADAT optical inputs of the Fireface 800 are fu lly compatible with all ADAT optical outputs. RME's unsurpassed Bitclock PLL prevents cli cks and drop outs even in extreme varipitch op- eration, and guarantees a fast and low jitter lock to the digital input signal.
User's Guide Fireface 800 © RME 55 Special Characteristics of the SPDIF Output Apart from the audio data itself, digital signal s in SPDIF or AES/EBU format have a header con- taining channel status information. False channel status is a common cause of malfunction.
56 User's Guide Fireface 800 © RME 28. Word Clock 28.1 Word Clock Input and Output SteadyClock guarantees an excellent performance in all clock modes. Based on the highly effi- cient jitter suppression, the Fireface refreshes and cleans up any clock signal, and provides it as reference clock at the BNC output (see section 35.
User's Guide Fireface 800 © RME 57 28.2 Technical Description and Usage In the analog domain one can connect any device to another device, a synchronization is not necessary. Digital audio is different. It uses a clock, the sample frequency. The signal can only be processed and transmitted when all participating devices share the same clock.
58 User's Guide Fireface 800 © RME 28.3 Cabling and Termination Word clock signals are usually distributed in t he form of a network, split with BNC T-adapters and terminated with resistors. We recommend us ing off-the-shelf BNC cables to connect all devices, as this type of cable is used for most computer networks.
User's Guide Fireface 800 © RME 59 29. TotalMix: Routing and Monitoring 29.1 Overview The Fireface 800 includes a powerful digital real-time mixer, the Fireface mixer, based on RME’s unique, sample-rate independent TotalMix technology.
