z-q2 stereo digital parametric equalizer
z-qualizer digital parametric equalizer
z-q2 two-channel digital EQ
Simply put, the z-Q2 is one of the finest digital equalizers money can buy. The z-Q2 combines the precision and repeatability of digital with the ?openness? and ?airiness? of the best analog EQs. At the heart of the z-Q2 lies a 40-bit floating-point digital signal processor running Z-Systems? proprietary digital filtering algorithms. These algorithms are the secret to the z-Q2?s outstanding sound quality.
The z-Q2 is a six-band stereo parametric equalizer that operates entirely in the digital domain. It can handle up to 24 bits at sample rates up to 96 kHz.* The z-Q2 can output 24, 20, or 16 bits and features POW-r wordlength reduction, the new industry standard.
The z-Q2 supports both M/S (mid-side) encoding and decoding in addition to the usual stereo-linked or dual-mono operation modes. Such flexibility allows the unit to handle separate processing on the mid and side components. The z-Q2 also features MIDI system-exclusive dump-and-restore capability, which allows you to save and recall the z-Q2?s presets from a computer running any MIDI sequencing program. And the z-Q2 can be snapshot-automated using MIDI program change commands. This equalizer is very simple to operate; the large knobs sweep without glitches. The filter center-frequencies, located on a 1/6-th octave grid, provide fine control of bandwidth and gain. Unlike other digital equalizers, the z-Q2 will never sound strained or brittle, even when providing narrow-band boost or cut at the frequency extremes. Digital EQs never sounded this good!
