Among professional audio interfaces for large studio use there are devices, which can work through FireWire/USB/MIDI ports, for example, Behringer FIREPOWER FCA610; it can work with smapling rates up to 96 kHz and 24 bits per sample precision. On its front panel there are : 2 combined XLR/TRS 1/4″ jack inputs, able to work in instrumental Hi-Z and microphone modes, instrumental mode, compressor, +48 V phantom power and PAD function switch buttons and their LED work indicators and amplification level control knobs for both inputs ( to them MIDAS preamplifiers are connected ); 2 TRS 1/4″ jack headphones outputs with volume control knobs, stereo/mono and Direct Monitor function switch buttons with their states LED indicators; indicators of states of analogue inputs and outputs, FireWire, USB, MIDI, optical and coaxial inputs and outputs, digital connection selection switch, volume and mixing balance knobs and button-selector of channels for volume control. Back panel of card has : power adapter input; MIDI input and output; USB and FireWire ports; Kensington Lock slot; optical and coaxial inputs and outputs; 8 balanced linear TRS 1/4″ jack outputs; and 2 linear balanced input connectors of the same type.
Connectors of Behringer FIREPOWER FCA610 have following characteristics : frontal inputs ( 102 dB dynamic range, impedance 1 MOhm in instrumental Hi-Z mode and 3 kOhms in microphone mode ), back panel inputs ( dynamic range 100 dB, 47 kOhms impedance ), outputs ( 200 Ohms impedance, 8 dB maximal output level ), headphones outputs ( 10 Ohms impedance, 22 dB maximal output level ); device can receive power from 100 – 240 V and 50/60 Hz power lines and consumes 20 W of energy. Audio interface sizes are 50 ( height ) x 241.3 ( width ) x 161 ( depth ) mm and mass is 1.1 kg ( it seems, that its body is made from aluminum ). For it drivers are released for Windows XP, Vista, 7, 8, 8.1 and 10 with ASIO 2.0, WDM and MIDI interfaces support; in Mac OS X device works without additional drivers with support of Core Audio interface; through them device works with modern DAWs : FL Studio, Cackewalk Sonar, REAPER, Avid Pro Tools, Ableton Live, Steinberg Cubase and others.
Package contains : Behringer FIREPOWER FCA610 external audio interface itself, USB and FireWire cables, power adapter, warranty card and user’s guide; after purchase there is ability to download from manufacturer’s website DAW Tracktion and VST/AU effects and instruments sets. Audio interface is great : with large amount of connectors and good characteristics, it is designed for professional studio use and has according price; for smaller sized studios there is ability to find audio interfaces of Steinberg, Behringer itself, Focusrite, Roland, ESI, M-Audio and other manufacturers production with smaller connectors amount, the same quality of components and lower price.
