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, the L gain controls the M level, and the R gain controls the S level.

Equalization

The equalization in the z-q2 is performed with floating point arithmetic and 

uses proprietary low-distortion algorithms developed by Dr. Glenn Zelniker. There 
are six bands, including two first order (6 dB per octave) shelves and four 
parametrics (bell curves). 

Stereo (ganged EQ channels):

Press the lo shelf button (on the top left). The display should look like:

S +00.0   56 Hz 

Rotate the left knob to change the gain of the low frequency shelving equalizer. 

Rotate the middle knob to change the frequency below which the shelving action 
takes place. This frequency is at the nominal 3 dB point of the curve. The first-
order equalizer is extremely gentle and quite natural-sounding. The S stands for 
stereo, and when the screen has an  in it, frequency and level control for both 
stereo channels are ganged together.

Separate Left and Right Channel EQs:

Press the lo shelf button again. The display now reads:

L +00.0    56 Hz. Here you can display and adjust the left channel shelf 

independently.

Similarly, press the lo shelf button again to display and adjust the right channel.

Now, press lo shelf again to return to the S display. If you altered either the 

frequency or the level of one channel, you will see one or two corresponding
