Our goal in the development of this device was to set a new milestone in equalization and at the same time to achieve a symbiosis of solid state and tube technologies. The result of two years' development, the TUBE ULTRA-Q, gives you absolute control over your audio signal and the power to lend more presence and liveliness to your music. The TUBE ULTRA-Q T1951 features four fully parametric stereo bands. The low and high-frequency bands can be used as shelving filters, allowing you to effectively eliminate low-frequency disturbances and high-frequency noise.

Extended information

Professional quality, flexible features

Our TUBE ULTRA-Q equalizer/notch filter is an absolutely professional device, offering all the audio characteristics you expect from a first-class equalizer. Its four fully parametric bands with adjustable bandwidth from 0.03 to 2 octaves enable attenuation of problematic frequencies as well as creative sound design, with a precision no graphic EQ can offer. The "constant Q" principle of the TUBE ULTRA-Q's filters ensures that level, frequency and bandwidth settings do not affect each other, allowing you ultimate freedom in sound shaping. The tried-and-true parallel filter architecture minimizes the phase shifting problems that are inevitable with serial filter configurations. And, like all units in our VINTAGER line, the TUBE ULTRA-Q also incorporates our specially developed ULTRATUBE circuit, which lends additional warmth to the signal.
