BlueBird HIFI Exquis USB Coaxial SPDIF Triple Decoder DAC PCM1794 + WM8805 Delicate Sound and Enhance the Analytical A Type
Use brief introduction:
- The "Dig in" led is a Coaxial/Optical inputs presence indicator, it lit only when you plug a Coaxial or Optical sound source.
- When you plug Coaxial or Optical cable, please disconnect the USB cable, because Usb connection is first the highest priority.
- Then switch in back panel is for Coaxial(UP) and Optical(Down) selection.
- We have not product manual with. but please feel free if you have any question.
- The overall use of high hardness aluminum chassis, the front panel is 6MM thick brushed panel. After the majority of the friends who gave advice. The overall design ward, athletic. Simplicity.
- A type amplfiier has only one interface for soundbox or headphone amplifier
- Size: Height 52mm, width 125mm length 220mm..
- SPDIF optical input (decoding): 24BIT 96KHZ
- Coaxial input (input): 24BIT 192KHZ
- USB input: 16BIT 48KHZ
- Output: RCA stereo audio signal
- Input voltage: Only 220/230V available
- Weight: 2.5kg
- Power parts: part are independent of each module power supply module, active crystals are made of two parts are AMS1117 independent power supply, and the use of magnetic beads to remove high-frequency burrs. Make crystal power cleaner. More stable, since to ensure long-term stability pulse. In order to ensure that there is no crackling sound glitches during play. Each module is powered independently to prevent the interference between the modules. Reaches a very high signal to noise ratio.
- Chipset solution uses PCM2706 + PCM1794 + WM8805.
- USB data is entered directly into the PCM2706 and demodulated data to I2S bus in the form of transfers to the DAC chip. PCM2706's performance will be better than many other USB decoder chip.
- Optical fiber, coaxial, USB decoder chip PCM1794, PCM1794, throughout the series are currently decoding the best decoder. The price is highest. PCM1794 sound sweet and delicate, elastic control well.
- Coaxial fiber optic receiver circuit using WM8805 digital receiver demodulation do to reach the receiver's ability to 192K. And have a good jitter suppression, more stable performance superior. USB receiver with I2S treatment using functional PCM2706, control between the various chips are used to control the hardware or software crash problem does not appear to bring BUGGER distress. 74HC157D by Philips PLL SPDIF signal, the overall control of each communication module.
- Below this is finalized toroidal transformer, using plastic irrigation package, high security, because there is - Plastic irrigation So good heat dissipation, and the primary and secondary layer are coated with tin foil shield, yellow wire is a ground wire . , there will be more clean output current, high current, enough to provide low-frequency power. Elasticity. Easily controlled.
- Op-amp use US SNE5532N, so much about reputation.
- Optical SPDIF and coaxial, relatively large amount of information translate, so the use of a dedicated high-speed audio feedthrough coupling capacitance. The sound is more delicate. Realistic, wider sound field expansion. Details expression more perfect
