Gainesville, Fla., April 28, 2000 -- Z-Systems announces the z-Q6/z-CL6 surround-sound mastering suite for surround mastering. Comprised of the z-Q6 six-channel digital mastering equalizer and the z-CL6 six-channel digital dynamics processor, the z-Q6/z-CL6 suite incorporates Z-Systems's proprietary digital signal processing algorithms, intuitive user interfaces, and the highest-quality parts. Both units feature six channels of 24-bit /96 kHz digital processing and the ability to handle multiple simultaneous sample rates and wordwidths within each channel group.

Z Systems' z-Q6/z-CL6 surround-sound mastering suite

The z-Q6 offers four bell-shaped filters and two shelving filters per channel, as well as individual channel volume offsets and a master volume control.

The z-CL6 offers six channels of compression/limiting with variable ratio, attack, release, threshold, and make-up gains per channel. In addition, the z-CL6 features a sophisticated linking mechanism whereby the different channel groups can be custom-tailored to trigger and compress in unison or separately.

Both the z-Q6 and the z-CL6 feature POW-r wordlength reduction and MIDI automation for snapshot automation. The z-Q6/z-CL6 are available individually or together as a suite.

"I called Glenn Z and accused him of hidden A/D and D/A converters inside, along with six channels of Pultec Tube EQ.... The z-Q6 is one of those exceptional pieces of equipment that has a quiet elegance about it... It only does one thing and it does it to virtual perfection." Glenn Meadows, Audio Media Magazine
