SIGNAL LEVEL

HARM 2 HARM 3 SPEED = 0 SPEED = 1 HARM 2 GAIN HARM 3 GAIN
+24 dBu 17.3 % 19.7 % 15.5 % 21.9 % -0.7 dB -0.7 dB
+14 dBu 7.6 % 3.5 % 16 % 14.2 % 0.9 dB 2.9 dB
+4 dBu 2.8 % 0.6 % 1.3 % .05 % 1.3 dB 3.6 dB
-6 dBu 0.9 % 0.2% .04 % .03 % 1.3 dB 3.6 dB

Gain change is referenced to having the color function off, it shows some compression with both the even and odd harmonic controls
All distortion wave measurements use a very low distortion sine wave as the source
They are analog measurements.


The top wave shape is a vocal recoding. The bottom is the same slowed down by the speed control; this is an extreme case to show the effect on the wave shape

 

 

EVEN HARMONIC DISTORTION WITH LEVEL:

 

 

ODD HARMONIC DISTORTION WITH LEVEL:

 

 


FREQUENCY RESPONSE OF WITH THE SPEED CONTROL SET TO 1
NOTE: LOW LEVEL SIGNALS HAVE A NEAR FLAT RESPONSE
HIGH LEVEL SIGNALS ARE CHANGED:
