Frontal panel of card contains : 2 combined XLR/TRS inputs with professional VS Preamps, one of which is switchable instrumental Hi-Z/Lo-Z, second is microphone input, to which phantom +48 V power can be connected; amplification levels controls for them; volume control for main analogue outputs of card and for monitor headphones; TRS 6.3 mm ( 1/4″ ) jack output for headphones themselves. Back panel of card contains : USB port for communication with computer and for powering from it; DC input ( it is not supplied with card ); MIDI input and output for instruments and other devices; 2 TRS 6.3 mm ( 1/4″ ) jack analogue balanced outputs ( they neutralize all noise signals, which are added to main signal, when it is transmitted in the cable ); sampling rate switch ( 44.1 or 48 kHz ); phantom power switch; instrumental input switch Hi-Z or Lo-Z; Direct Monitor mode switch for headphones ( mono, stereo, off ); power button; and ground contact.
