Waves Renaissance EQ Study. Version 5.9.7 AU

Measurements at 96kHz, 24 bit, 0.7Hz resolution, Blackman-Harris windowing.

1. Null Performance

The Level Adjust has a +12 to -24dB range. This thing is just a bus wire 

with all bands active with null settings. That small 2nd harmonic you see in the 

plot is from my signal generator.

Magnitude, phase response and harmonics with null settings:

2. Low Shelf

200Hz cutoff.  +3 to +18dB shown. Q set to minimum (0.71).    2nd plot shows overshoot increases as Q value increases.  0.71 - 1.41 shown.

3. High Shelf

2kHz cutoff. -18 to +18dB shown. Q set to minimum (0.71).    2nd plot shows overshoot increases as Q value increases.  0.71 - 1.41 shown.

4. Peak Filters

Q fixed at 6.50, (maximum). 2nd plot shows Q at 0.26 (minimum). 500Hz shown, but Q remains constant regardles of center frequency.

5. High Pass Filters

Note that the Gain control has no effect when the band uses this filter type. Change it 

all you want, but it won't make any difference. Most notable here is the odd low frequency 

pass band that appears after increasing the Q parameter past 1.0.

Magnitude and phase response at 100Hz cutoff with various Q settings from min to max:

6. Low Pass Filters

Here we get a similarly odd high frequency pass band that appears after increasing the Q parameter past 1.0.

Magnitude and phase response at 2kHz cutoff with various Q settings from min to max:

5. Harmonic Distortion

Peak band set to +6dB @700Hz.  700Hz test frequency.
