Excellent RME sound card with Firewire speed. Power supply and RME Manual supplied. The RME Fireface 400 Firewire Audio Interface is a high-quality device designed for professionals involved in home recording, live sound, and studio recording. It offers a maximum sampling rate of 24 Bit (192 kHz) and has 36 channels. This rack-mountable interface has 8 line inputs and 2 mic inputs, making it suitable for recording artists and sound engineers. The device comes with various input/output ports, including Firewire Interface, MIDI I/O, Analog In, Analog Out, Headphone TRS 1/4 Out, S/PDIF RCA In, S/PDIF RCA Out, and World Clock I/O. It is PC/Mac compatible and has a range of features, including being powered, having a sleek design, and being made in Germany. Analog I/Os : Eight inputs and outputs (balanced, output 7/8 unbalanced) with software controlled switching of the reference levels (-10 dBV, +4 dBu, Lo/HiGain), of course realized discretely in the analog domain, guarantee highest dynamic range and highest fidelity. The Fireface 400’s front panel features 2 balanced microphone inputs with a digitally controlled input stage, individually switchable 48 V phantom power, and Neutrik Combo connectors for XLR and TRS. These can also be used as additional Line inputs. A gain of up to 65 dB, adjustable in steps of 1 dB over a range of 55 dB, exceptional EIN performance even at low amplification settings, and extremely low THD+N let these preamps surpass those of other devices that cost several times the price of the Fireface400. All level settings are 100% reproducible and can also be adjusted by software comfortably. Inputs 3 and 4 are stunningly flexible balanced universal inputs. Firstly, they operate exactly as inputs 5 to 8 on the rear and can be adjusted to accept standard studio input levels (+4 dBu, LoGain). Also, the input impedance can be switched from Line (10 kOhm) to Instrument (470kOhm). An additional analog input amplification of up to 18 dB (in steps of 0.5dB) is also available. In short: There’s no signal that these inputs can’t deal with perfectly! Inputs 5 to 8 on the rear feature RME’s proven level references. 10 dBV, +4 dBu und LoGain can be selected in the settings dialog, equivalent to +2 dBV, +13 dBu und +19 dBu for digital full scale. The same applies to the balanced rear analog outputs 1 to 6. The high power phones output offers high volumes even with low-impedance headphones, and represents playback channels 7/8. All outputs can be used for ASIO Direct Monitoring purposes. Digital I/Os : An ADAT optical I/O allows for a connection and insertion of effects devices, mixing consoles or external converters. Of course, these 8 channels are available simultaneously with the analog channels. Using an additional ADI-8 DS or OctaMic D, you’ll get 16 analog inputs and outputs, which remain still 12 at 96 kHz. The coaxial SPDIFI/O, which is fully AES/EBU compatible (as is common for RME), also works up to192 kHz, which means that at the highest sample rate, 8 analog and two digital inputs and outputs are directly available. SPDIF optical can also be accessed through the optical I/O. Thanks to an internal flash memory, all settings including TotalMix are recalled during boot. The device can thus be configured and used as a stand-alone device, without being connected to a computer, e. As a submixer, A/D and D/A-converter, headphone mixer, format converter, instrumentor microphone pre-amplifier, monitoring mixer and much more. The Fireface 400 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 care of optimal AD/DA conversion quality, thus guarantees crystal sound quality, completely independent from the reference clock’s quality. SteadyClock allows the unit to control the sample rate freely on itsown. 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%. Of course the Fireface 400 offers a second FireWire port for hub functionality. Up to three devices can be connected to one FireWire interface and operated in parallel. The renowned Fireface 800 shares the same driver, allowing mixed setups. Input AD: 6 x 1/4 TRS (4 x Line, 2 xLine/Instrument), 2 x XLR/TRS Combo connector (2 x Mic/Line), all servo-balanced.
