PCI Compatible,
Multi-Function Sound Editing for Your PC Audio
Studio
The INFRASONIC QUARTET is a multi purpose pro audio interface card using
stable PCI bus technology. QUARTET provides high quality,
multi-function, sound editing for your home
studio.
QUARTET has better
performing analog I/Os than other cards in its
class. It supports a 192 kHz ADC sample-rate with
full 24-bit recording. The high-quality AD/DA
converter has 115dB signal-to-noise (S/N) ratio.
The high-end components in the analog circuit
improve dynamic range by 10dB.
Other features include a MIC preamp, direct
instrument input, MIDI I/O, Coaxial I/O, Word
clock I/O and Dual Headphone amplifiers QUARTET is professional gear
that will satisfy in features, performance and
convenience.
