The Sonic Frontiers UltraJitterbug enhances the performance
of virtually any high end digital-to-analog processor.
In response to the increasing understanding of
word-clock jitter as a major barrier to the improved
sonic performance of digital audio, Sonic Frontiers
introduces a product 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” signal to a digital-to-analog processor.
The UltraJitterbug has three digital inputs - 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 digital input data, decodes it and attenuates 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 and outputs are isolated by their own custom, wide bandwidth, low capacitance pulse
transformer. These transformers prevent any common mode noise in the digital signal from being
coupled into the sensitive internal circuitry of the
UltraJitterbug and the DAC. They also prevent the
formation of a low frequency (ground loop) connection 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”).
Further, the inputs are multiplexed relays which provide
low impedance paths for the selected signals to pass
through and high isolation between the selected input
and the other unused inputs. Careful trace routing and
guarding insure that the PC layout does not contribute
to crosstalk. Separate ground planes are used for each
circuit section to keep the noise of one section from
contaminating another.
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 performance in the improvement of a digital signal through jitter rejection, the UltraJitterbug is
a truly affordable upgrade to your existing digital-toanalog processor.

OPERATION, CONNECTIONS AND CONTROL FUNCTIONS
A- Digital Source Select Switch - This three-position toggle selects the desired input path,
(Toslink - plastic fibre optical, AES/EBU - XLR connector, or RCA - coax connector).
B- Source Indicator LED - One of the three LEDs will light to indicate the selected source of input.
C- Locked/Unlocked LED - This LED will light when the UltraJitterbug is locked to an incoming
data stream. When the LED is off the UltraJitterbug is not locked and the outputs are muted.
D- IEC Socket - The detachable power cord connects here. When the UltraJitterbug is plugged in
to a power source the unit is on.
E- Optical - Toslink Input - This is the input socket for a S/PDIF - Toslink - plastic fiber optic
connection to the digital source.
F- AES/EBU Input - This is the input socket for an AES/EBU - XLR connection to the digital source.
The AES/EBU cables impedance should be 110 ohms.
G- Coaxial Input - This is the input socket for a coaxial - S/PDIF - RCA connection to the digital
source. The coaxial - S/PDIF - RCA cables impedance should be 75 ohms.
H- Coaxial Output - This is the output socket for a coaxial - S/PDIF - RCA connection to the
digital-to-analog processor.The coaxial - S/PDIF - RCA cables impedance should be 75 ohms.
I- AES/EBU Output - This is the output socket for an AES/EBU - XLR connection to the digital-
to-analog processor. The AES/EBU cables impedance should be 110 ohms.
Note: For best performance, connect only one output at a time. Any number of inputs may be
connected at one time.
The UltraJitterbug is factory set for the correct operating AC voltage for the area in which it is sold.
If a different operating voltage is required, please contact an authorized Sonic Frontiers dealer,
distributor or the factory directly.

LIMITED FIVE YEAR WARRANTY
Sonic Frontiers, Inc. warrants to the purchaser that each
UltraJitterbug is free of manufacturing defects for a period
of five (5) years from the date of purchase. To receive this
warranty, the original purchaser must mail to Sonic
Frontiers, within thirty (30) days from date of purchase, the
enclosed Warranty Registration Card completed. Sonic
Frontiers, Inc. will then validate the warranty to the original
purchaser. This warranty is subject to the following conditions and limitations:
1
. Warranty applies only to the original purchaser.
2 . This warranty is void and inapplicable if the product
has been handled other than in accordance with the
instructions in this Owner’s Manual, abused or misused,
damaged by accident or neglect or in being transported,
or the defect is due to the product being tampered with,
modified or repaired by anyone other than Sonic Frontiers,
Inc. or an authorized Sonic Frontiers’ repair depot.
3 . Warranty does not cover normal maintenance.
4 . Sonic Frontiers, Inc. shall not be responsible in any
