This product represents our latest breakthrough in our never-ending quest to improve the world's sound. Aside from the powerful array of features packed into a single unit (graphic EQ, FBX filters, parametric filters, high and low cut filters, delay, compression, and limiting), the Graphi-Q2 also offers a choice of user interfaces. Computer control: learn to love it. As the world becomes an increasingly digital place, the computer is omnipresent. Some regard this as a mixed blessing. In audio applications, the downside of computercontrolled digital audio stems from the unfamiliarity and operational limitations of its control interface. After years of experience with analog controls, many sound engineers prefer the "hands-on" approach to control audio with knobs and faders. It's intuitive and direct. To the analog lover, typing commands on a keyboard feels awkward and may require redirecting one's attention to the control interface, rather than the sound emerging from the speakers. On the other hand, there is no question that the digital signal processing available through a computer interface offers improved precision and reliability of control over your audio. Equalization adjustments in the digital realm are exceptionally accurate, offer pinpoint resolution, and minimize phase distortion and frequency drift. Compressor parameters not only can be set quite precisely, but also offer an expanded range of adjustment and ease of storage and recall that are much more difficult to achieve with analog technology. And, with the Sabine FBX algorithm, one of the most serious problems of audio amplification -- that lovely howling sound we call feedback -- can be removed with the precision and delicacy of laser surgery.
