Our belief in totally pure music required an enormous effort on our part to eliminate the most minuscule of interfering influences. 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. 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 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. 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. 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.
Signals which fulfil the purity requirements are de-coupled completely from the input jitter by switching to the Masterclock. The incoming signals are further processed by precision oscillators with the best available femto-clock accuracy. 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.
