An external clock might seem unnecessary when the main player or DAC already clocks data internally, however improving precision in the data flow always pays.
An obvious and immediate benefit is that musicians are playing more together, ie timing is improved, so the music flows far better and is more dynamic and lively – in short, more involving.
An important feature of the U-Clock is its USB input, able to accept high-resolution 24/96kHz computer files downloaded from the internet and convert them to standard SPDIF format, to be fed into any standard digital input such as on the Puccini player. Crucially, the U-Clock's computer connection (Mac or PC) is "Asynchronous", meaning that it locks the computer's "dirty" output to its own clock to minimise jitter.
The jump in performance above CD replay is very significant, being sweeter and more naturally detailed. We regularly demonstrate this in the studio and at shows.
From a customer who added a U-Clock to his Puccini: ' I think my clockless system was very good, but with the clock in there, what a difference. Now I get the total acoustic space of the orchestra together with improved timbres associated with woodwind and brass - truly an essential 'no-brainer' upgrade; I'm thrilled with the total sound.' Tony H Farnborough
The U-Clock can be used with other manufacturers' players that adhere to the Word Clock standard on 75 Ohm co-axial cable.
