(6 dB correction). 1.3 Control elements The BEHRINGER TUBE ULTRA-Q has four parametric filters organized in 4 different frequency bands. A backlit VU meter shows the input or output level. Each channels comes with a Warmth control, and a tube window. - Page 8 All manuals and user guides at all-guides.com TUBE ULTRA-Q T1951 The FREQUENCY control selects the filter’s center frequency, which can be freely chosen within the frequency range of the associated band. The LEVEL control determines the amount of level boost/cut. The setting range is from -15 to +15 dB.

2. OPERATION 2.1 Introduction The BEHRINGER TUBE ULTRA-Q gives you a combination of all technical properties both of parametric equalizers and of narrow-band notch filters. With its excellent audio quality and outstanding specifications it is simply better than any conventional equalizer. The ULTRA-Q can be used to make up for frequency response deficiencies and to creatively process any audio material, thus giving you undreamed-of equalization flexibility. - Page 10 All manuals and user guides at all-guides.com TUBE ULTRA-Q T1951 like feedback. In live applications uncontrolled feedback can cause damage to loudspeakers and amplifiers. By means of the INPUT control you can adapt the sensitivity of the TUBE ULTRA-Q to the input level. The sensitivity can be varied within a range of -15 to +15 dB.

You can now drastically increase the effect by turning up the WARMTH control. With the tube stage featured in the BEHRINGER TUBE ULTRA-Q you can add the typical tube sound with the WARMTH control. Increasing amounts of upper harmonics generated by the new UTC circuitry are then added to the signal. -

At the high cut side you can reduce tape hiss for example. Use this feature with caution however to prevent the material from becoming muffled or sharp. It is advisable to use a dedicated denoiser like the BEHRINGER MULTIBAND DENOISER SNR2000 to effectively eliminate tape noise. The TUBE ULTRA-Q is well suited for in-the-field problem solving when unexpected hiss arises. - Page 13 All manuals and user guides at all-guides.com TUBE ULTRA-Q T1951 Center frequency (Hz) Effects on music 1/3 octave Fundamentals of bass drum, tuba, double bass and organ.

In rooms with poor acoustics or a high level of background noise, both natural sound and acoustic power can usually not be realized simultaneously.

All manuals and user guides at all-guides.com TUBE ULTRA-Q T1951 In complex sound reinforcement systems comprising different speakers located in varying acoustic environments (e.g. theaters with front speakers, various side-fill speakers and/or balcony speakers) each single time-delayed channel should be equipped with a separate TUBE ULTRA-Q, as this is the only way to make provision for varying room acoustic and to adapt the speakers specifically. -

All manuals and user guides at all-guides.com TUBE ULTRA-Q T1951 In a triode the capacitance between grid and anode is a problem with regard to high frequencies and large amplification factors. For this reason, the pentode has a positively charged screen grid between the control grid and the anode. -
