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.
