M-Audio FireWire 1814 - Sound card - 24-bit - 192 kHz - IEEE 1394 (FireWire) Sample rates: 44.1 to 192 kHz on all analogue outputs and analogue inputs 1/2; 44.1 to 96 kHz on analogue inputs 3 to 8. Analogue inputs: two, balanced XLR with switchable global +48V phantom power and 1.8k(omega) impedance, or unbalanced TS quarter-inch jack instrument with 500k(omega) impedance, both using mic preamp with up to 66dB gain plus optional 20dB pad, or unbalanced line-level TS jack at fixed -10dBV sensitivity and 10k(omega) impedance, plus six further identical unbalanced line-level TS jacks. || Analogue outputs: four, balanced/unbalanced TS quarter-inch jack at -10dBV level, two headphone with individual level controls. Digital I/O: ADAT optical in and out switchable to S/PDIF optical, co-axial phono S/PDIF in and out (both S/PDIF outputs support AC3 and DTS formats), MIDI In and Out, two six-pin Firewire ports, word clock in and out (will sync to external word clock at sample rates up to 96kHz). Frequency response: 22Hz to 22kHz 0.1dB at 48kHz sample rate, 22Hz to 80kHz 1dB at 192kHz sample rate. Dynamic range: inputs 105dBA, outputs 107dBA. THD + Noise: less than 0.003% at -1dBFS. Dimensions: 10.5 x 7 x 1.875 inches. Weight: 3.44lbs.
