Q3 Coil Equalizer 500 Module

OVERVIEW

The Radial Q3 is different... it does not follow tradition. The usual 3-knob EQ approach is 
to select a frequency band using some sort of rotary switch, then set the Q or width of the 
peak frequency and then adjust the amplitude of the effect to suit. To create truly usable 
audio curves, you really need to combine multiple frequency bands together and mix their 
effects. In other words, to recreate the type of curves we have conjured up inside the Q3, you 
would need at least two bands and 6 control knobs. This is ‘practically’ impossible in a small 
format module like the 500 series as the controls would be so tightly packed, they would be 
unusable.

To fi t a coil EQ into the 500 series format, a completely different approach was needed. The 
Q3 changes convention by giving the user a mind-numbing selection of over 12,000 EQ 
possibilities using only three knobs and a few switches. Each 12 position switch is packed 
with 11 preset curves that have been carefully selected after exhaustive listening tests. 
These were evaluated on voice, bass, acoustic guitar, electric and on drums and compared 
using both dynamic and condenser microphones. 

We then set about testing how each curve would sound in tandem. There is no doubt that 
while some curves will sound amazing on bass, the same curve may not suit mandolin. But 
with well over 12,000 combinations, you will surely fi nd lots of very usable sounds.
