12 TUBE UL TRA-Q T1951 Because of the wide overlap possibility of the different filters, the effect of two filters can be added together if so desired. This way an even greater attenuation or boost can be achieved. When notching out frequencies try to make the band as small as possible.

15 TUBE UL TRA-Q T1951 It is quite obvious that compromises must be made to meet these requirements. In rooms with poor acoustics or a high level of background noise, both natural sound and acoustic power can usually not be realized simultaneously. Priority must be given to one of these quality-improving measures.

18 TUBE UL TRA-Q T1951 allowed for loss-free copying of audio signals. As digital media were enhanced, however, many people began to miss the warmth, power and liveliness they knew from analog recordings. This is why purists still today consider digital recordings as sterile in sound.
19 TUBE UL TRA-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.

Each of the two tube halves amplifies the original signal and the signal modified in its phase spectrum (twin triode).
