Explore endless tonal options

The Q3 features four easy to use controls: top-end boost, mid-range cut, low-frequency bass boost and gain make-up to offset the signal loss that occurs when using passive equalization. Each of the three EQ bands employs a 12 position switch with a different preset curve at each position. These are carefully crafted to introduce subtle accents, huge hype and warm sounding cuts that will flatter and enthrall. Each EQ setting is augmented with a miniature toggle switch that enables you to attenuate the curve for more subtle effects to deliver a total of over 10,000 combinations of tonal bliss.

The Q3 specifications shown below provide the engineer with basic data such as noise and distortion. To truly understand the ‘functionality’ of the device, one is better served by reviewing the various frequency curves that are shown on the using page. Or better yet… by actually listening to the effect of the Q3 on voice, instruments and various program material. The Radial Q3 is not about clinical – it is about creatively applying the effect of a coil to add excitement to your music.
