Z-Systems z-Q2 - Manual

z-q2 operations manual
Introduction
Z-Systems model z-q2 6-band digital equalizer is based on the highly-
successful model z-q1. For those who are familiar with the z-q1, here is a list of the
extensive improvements we’ve put into the z-q2:
•Complete ergonomic upgrade. The z-q2 is much easier and more fun to use.
The front panel has been simplified, keystroke and hand movement greatly
reduced, especially the process of saving and recalling memories. All screens are
now non-modal, which in plain English means that you can navigate instantly from
any menu to any other. The system remembers the last mode of any button that you
used. Left and Right channel equalization can now be separately and easily
adjusted and inspected. The one-line display has some added features keeping it
simple, yet powerful.
•POW-R TM dither. The reknowned dither from the POW-R consortium is now
included. POW-R dither is so transparent that it yields nearly 20-bit
psychoacoustic performance from a 16-bit master with virtually no penalty in tonal
balance, depth, space or width.
•MIDI control. Memory recall can now be recalled by an external MIDI
controller, and the entire state of the memories can be stored or recalled with
Sysex.
•M/S. A bit-transparent M/S encoder and/or decoder can be inserted in the
signal path.
•Range of gains has been optimized for very fine 0.1 dB equalization near 0
dB, and more coarse as the gains become extreme.
•Range of frequencies has been extended to 20 kHz for that ultimate “air
control”.
•Range of Qs now includes a fine range around 1.0, to include the most
common and musically useful Qs.
•Power-Down state. The z-q2 writes its current state into memory whenever
power is lost.
•And all the original low-distortion Zelniker equalization algorithms are still
here!
