Продам Sonic Frontiers UltraJitterBug - подавитель джиттера цифрового сигнала.
Реализован на чипе UltraAnalog AES21, внутри полностью линейной питание, в общем правильный топ-олдскул.
По сути уникальный фильтр между источником, к примеру CD-транспортом и ЦАПом. Может существенно улучшить сигнал, приходящий в ЦАП без вмешательства паяльником в транспорт, как будто транспорт заменили на уровень или два выше. Верх становится чище, низ собраннее, тишина чернее, КИЗы собираются, а сцена расходится в ширь и в высь.
Три входа AES/EBU, Coax и Toslink и два выхода - AES/EBU и Coax. Попутно можно решить проблему нехватки входов в ЦАПе или конкуренции за один тип входа от двух источников. Можно легко переключаться без перетыкания кабелей.
Кабелей и родной коробки в комплекте нет, только сам девайс.
Цена 300 долларов США по курсу продажи валюты.
На момент размещения объявления это 23’000 рублей.
Продажа в Москве, самовывоз, отправлю СДЭК по России после 100% предоплаты.

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.
