The Ultra-Q yields absolute control over audio signals, adding liveliness and presence to your music. Its 4 bands have an adjustable width from 0.03 to 2 octaves allowing easy attenuation of problem frequencies as well as creative sound design. Each Ultra Tube circuit features a 12AX7A to lend added warmth to the signal. The lo- and hi-frequency bands can also be used as shelving filters, allowing you to eliminate low-frequency disturbances and high-frequency noise. The Q principal filters ensure that level, frequency, and bandwidth settings do not effect each other, and its parallel filter architecture minimizes phase-shifting problems.
