NXC09 AK4499 Digital Audio Decoder Bluetooth 5.0 Headphone Amplifier DAC DSD512 CSR8675 For LDAC

Description:
The first to use digital shaping technology for multifunctional digital audio decoder, soft control for ARM, DSD hard solution. CSR8675 Bluetooth 5.0 supports for APT-X, APTX-HD, LDAC, USB receiver for Amanero solution, TPA6120 professional headphone amplifier. Small size, exquisite workmanship, excellent performance and easy to use.

Advantages:
- FPGA digital shaping chip
- CSR8675 supports for aptX HD 48khz, supports LDAC 96khz, HD audio transmission
- British digital structure solution for ARM
- Full function remote control
- Italy daughter card
- Support DSD64-128-256-512
- PCM supports 32bit 384K
- HD large screen, clear at a glance
- AK4499EQ decoder chip
- AK4113 receiving chip
- TPA6120 professional headphone amplifier
- In-line dual op amp, ±14.5V power supply

Features:
- Italy USB Digital Interface-DSD Hard Decoding: Supports DSD hard decoding of all USB devices such as for IOS, Android, and computers (Smartphone USB connection needs to be equipped with OTG cable, and users need to prepare OTG cable).
- Pluggable op amp with independent op amp seat is adopted to support users to exchange and find the tone they want. The operational amplifier part adopts ±14.5V power supply.
- Applicable equipment: digital input: digital audio from optical, coaxial, USB, Bluetooth devices; analog output: red and white RCA output, 3.5mm amp output.
- The overall internal layout of the NXC09 digital audio decoder is elegant and beautiful, with selected materials.
- The hard-core Bluetooth chip guarantees lossless transmission.
- CSR8675 Bluetooth chip supports for APTX-HD, 24BIT/48K extreme solution. Support for LDAC 24BIT/96K lossless solution. Such a high transmission bit rate enables us to experience lossless sound quality in Bluetooth transmission equipment.
- For LDAC: CD-level Bluetooth sound quality, 94KHz/24bit high sound quality listening
- Bluetooth 5.0: Bluetooth stereo sound quality, lossless 24BIT transmission
- For APTX: When APTX HD is not available, it can still guarantee music playing.
- Bluetooth 5.0 uses that for LDAC to redefine high-definition wireless audio. 24bit 96kHz high-definition transmission can be achieved under partial code for LDAC, and Bluetooth can also be very HIFI from now on. (Note: The built-in decoding function of CSR8675 has been turned off, and AKM4499 chip is completely responsible for decoding output.) When the decoder is in non-Bluetooth source mode, it will automatically cut off the Bluetooth power supply and will be awakened again when needed.
- It adopts AK4499EQ four-channel decoding chip, and supports native decoding of 32bit/384kHz, PCM and 22.4MHz DSD signals. Able to provide 6Vrms balanced and 3Vrms unbalanced output power, 124/125DB unbalanced/balanced signal-to-noise ratio -138/-144DB unbalanced/balanced crosstalk and 0.0005%/0.0004% at1KHZ unbalanced/balanced THD+N total harmonic distortion.
- USB daughter card digital interface for Amanero solution: The effect is better than that for XMOS. PCM: 44.1kz, 48kz, 88.2kz, 96kz, 176.4kz, 192kz, 352.8kz, 384kz; DSD: dsd64, dsd128, dsd256, dsd512.
- For FPGA-XILINX digital shaping chip: Adopts digital shaping technology for XILINX to improve the jitter of clock signal, with better details, and at the same time to prevent switching pops. And the electromagnetic interference between each channel, output pure audio signal.
- For AKM-4113 Independent digital receiver chip: Coaxial and optical input sound more natural and professional. The independent signal receiving and processing chip is 65% higher than the previous generation, the sound is smaller, more delicate and rounder, and the level performance is obvious.
- For ARM-STM32F: Using the British digital architecture processing system for ARM, the overall collaboration effect is improved.
- Japanese in-line dual op amp: using 4pcs 5532DD op amps with high fidelity and low noise, its sound is full, flexible, full of charm, low frequency extension, and enjoyable like a tube amp.
- Linear boost conversion design: 12V DC single voltage input is first boosted and then converted to achieve a positive and negative 14.5V dual voltage power supply mode, so that the output effect of op amp is level and the listening effect is truly satisfied.
