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

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!

If in doubt, verify the internal power selector switch has been set to the proper voltage for your country before plugging in power! System menu dither, wordlength and sample rate display conn...

However, the ear can easily hear signal as much as 20 db or better below the wideband noise level, depending on the frequency and masking. That’s why we have to use dither noise, to eliminate low level distortion caused by dsp processing. Without dither noise, the sound of quantization distortion ca...

Midi #06 read no to change the midi channel, rotate the first knob. The channel is preserved in non-volatile memory at power down. Sysex read and dump. The second and third menu items are used for sysex dumps and reads. For a sysex restore of all 99 presets from a midi sequencer. When the second men...

And all equalization and gains are set to 0 db, the system remains perfectly bit transparent, since its ms encoder and decoder are exactly symmetrical, down to the last mathematical bit. You can leave the system in ms y, y mode if you wish and operate it as a stereo equalizer without any concern for...

Which should look like this: a=35 b=49 load there are two nonvolatile memory “spaces”, labelled a and b, which can be compared. Rotate the left knob to choose the memory number from 00 to 99 for the a space, or the middle knob for the b space. Memory 00 is a factory default, which is set to: ms n, n...

Gain press the gain button (the led next to the gain button illuminates) and see this screen: g +00.0 l +00.0 r +00.0 adjust the overall gain to avoid output clipping. Adjust left and right gains to taste. As mentioned previously, if a stereo signal enters the equalizer, and the ms encoder is on, th...

Asterisks in the s(tereo) display, for example: s +00.1* 56 hz* an asterisk indicates that there is a different setting between the left and right channels. This way you can instantly inspect if the left and right channels are identical. Just look for the asterisk to see if either frequency or level...
