2. PRODUCT DESCRIPTION
When we were creating the product our base was the USB/SPIDF converting (bridge) panel.
This panel includes the necessary components that make the quality digital data transmitting
possible. We based the whole product around this panel with the right sizing.
Our primary goal was to obtain maximum vibration absorbtion and leading the heat off in all
of the components.
When designing the product we took into account what kind of parts each base components
consist of, and how much heat should we dissipate from them, as well as which parts are extra
sensitive to vibrations. We decided that the best solution to that problem is developing an
aluminum monobloc case. That case should provide ideal vibration absorbtion and heat
protection to the high-end parts with perfect balance. That aluminum monobloc case
represents the design patterns of the typical Core Audio Ultimate High-End products.
The equipment operates with 230V/50Hz input voltage and it’s power supply is completely
separated for all stages with a low-noise analog power circuit. We use short and optimized
PCB conduction bands. For the external power supply we use a high quality FURUTECH IEC
standard socket. The internal cabling is made with the highest possible quality Siltech cables
containing silver fiber.
The case of the device has a part specially made to actively take part in leading heat off from
the power circuit. On the main panel, among other, the followings are placed: the clock signal
controlling the XMOS XU2016 16 multicore microcontroller, the clock signal needed for
operating the standard clock signals of 44.1KHz and 48KHz (and multiplied versions such as
88.2 kHz, 176.4 kHz, 96 kHz, 192 kHz), and a different one for operating the USB port. All clock
signals are low jitter Crytek clock signals made uniquely for Core Audio. No matter the level or
stage, there are extremely short signal pathways using high quality, low heat-dependent parts.
The Core Audio Ultimate USB/SPDIF converter is also equipped with an i2S-HDMI output which
makes you able to connect it with devices having the available latest standard port.
The central control panel contains the most recent XMOS XU216 chip, guaranteeing that the
high definition contents sent through the signal pathway. To ensure the optimal operation we
