Each oscillator is reserved for a single clock family the Masterclock covers both the odd 44.1 kHz to 705,6 kHz clock as well as the even 48 kHz to 768 kHz clock. The incoming signals are further processed by precision oscillators with the best available femto-clock accuracy. Signals which fulfil the purity requirements are de-coupled completely from the input jitter by switching to the Masterclock. If those criteria are not met, the signals are cleaned again through a further PLL stage in a specially constructed second jitterbug this process reduces the residual jitter by a factor of 4. In the first stage the incoming signal delivers a raw clock pulse which is analysed very closely by micro-processors: the signal is then switched to the Masterclock - but only if its frequency and stability fulfil strict minimum criteria. The De-Jitter Masterclock was developed here in Herford, and constitutes a consistent audiophile response to jitter: in a multi-stage process the incoming signals are examined, and even the largest of jitter artefacts are removed. This type of interference - known as jitter - is caused by minimal timing errors, which still manage to exert a harmful influence on the sound experience unless they are removed before the conversion into analogue signals. The T+A De-Jitter Masterclock was developed with the goal of freeing all T+A DACs from such interference signals, and in particular those which result from the use of computers. Our belief in totally pure music required an enormous effort on our part to eliminate the most minuscule of interfering influences.
