In response to the increasing understanding of word-clock jitter as a major barrier to the improved Sonic performance
of digital audio, Sonic Frontiers introduced that verifiably and significantly reduces jitter. The Ultrajitterbug
is a digital reclocker that reduces and rejects jitter from a digital source such as a CD player or DAT machine,
and supplies a "clean" single to a digital-to-analog processor.
The Ultrajitterbug has three digital input-AES/EBU via XLR and S/PDIF via RCA coax and Toslink plastic fibre optic
- Which feed the new UltraAnalog AES21 AES/EBU ultra-low jitter input receiver. The AES21 receives the jitter
that is present on the incoming digital data stream.
Many special measures were taken to reduce contaminating noise and to prevent crosstalk.
The inputs an outputs are isolated by their own custom, wide bandwidth, low capacitance pulse transformer.
These transformers prevent any common mode noice in the digital signal from being coupled into the sensitive internal
circuity of the Ultrajitterbug and the DAC. They also prevent thhe formation of a low frequency (ground loop)
conection with the Ultrajitterbug which could significantly increase 60Hz "hum", as well as couple the data
that is desired to be passed without limiting the bandwidth (droop").
The power supply is a full linear regulated design with four separate linear regulators.
The digital and analog power supplies are provided with separate regulators and the output driver
has its own regulator to insure that the output is as free from unwanted noise as possible.
The design of the power supply is conservative to insure that the temperature of the regulators
remains low under all operating conditions thereby providing a very long operating life.
The Ultrajitterbug is built under strict quality control utilizing the highest calibre of parts available.
With its proven peformance in hte improvement of a digital single through jitter rejection, the Ultrajitterbug
is a truly affordable upgrade to your exiting digital-to-analog processor.
