A1 HIFI Streaming Music Player Multifunctional Integrated with DAC and Dual Headphone Amplifier for SOUNDAWARE Red

Description:
- Support ROON Ready, Airplay, DLNA, Samba etc., sampling rate to PCM 384kHz and DSD256. Patented FPGA technology optimized LAN/WAN player with dual headphone output.
- HIFI level Bluetooth dual headphone output processed by FPGA clock.
- Connected to appointed USB driver, A1 can play and rip CD in high precision mode.
- Large capacity SD card/HDD supported, high performance off-line music player.
- Inherited technology from 300 series, A1 has the interface and transport system based on the latest patent FPGA algorithm.
- Patent structure designed specialized for Hi-End
- Provide each format of music with precise clock, denoising process and synchronous playback.
- After 5 times FPGA upgrade, the structure achieved a new high level in both functionality and performance.

Features:
- HIFI system (32Bit/384kHz)
- Lasted good sound quality
- Life beyond ten years
- Low power consumption and high performance
- All linear low noise
- Flagship structure, major breakthrough
- HiFi is more than above
- Big screen & big font, plug & play storage
- Direct operate via buttons and remote, regardless of the distance.
- Abundant online music supported

Advantages:
- Performance doubles with main clock remained too low to reduce greatly of the low frequency noise because of rising clock frequency.
- Redesigned CPU board and program optimization improve 30% of the CPU performance.
- Core technology & HiFi material
- Full DC single end amplification technology
- Reduce the distortion of DA chip in amplification process. The sound is more real without the distortion of coupling capacitance’s phase position, frequency response and information content. But it has higher standard of the material precision and matching. So, we choose high-precision MUSE operational amplifier, thus the analog amplifier of A1 all adopts high-precision material to amplify symmetrically.
- For MR1 V2 decreases internal resistance of analog power supply from 200 milliohm to 10 milliohm instantaneously, discharge ability increases by 20 times with lower noise to better output perfect waveform.
- Adopting high quality iron core transformer and high current power filter, analog and digital linear power supply separately. For Soundaware remains independent power supply for ARM, USB, FPGA and analog linear, almost all the 20 secondary power supply lines adopt the LDO voltage stabilization with ultra-low noise. Core capacitors include for rubycon ZLH class high frequency low resistance series, for ELNA CERAFINE and other classic material. Tune style is closer to for M2pro and for A280 Femto, featuring transparent, delicate and Hi-Res sound.
- Adopting the same-designed FPGA of A300 plus independent high precision ultra-low noise clock to process secondary jitter process, so as to achieve high fidelity playback from Bluetooth.
- High performance sound card and interface technology: for XMOS provides data channel, FPGA processes jitters in the standard of HiFi level, offering an interface that combines cellphone, Pad and PC. Then the amplification works in mono, native and full DC condition, plus better isolation and optimization, thus perform close to the playback effect of FPGA.
- Infrared/ buttons, cellphone/buttons, cellphone, tablet/ App, PC software control
- A1 is designed to be more than just an excellent music player, but the highlight of the whole interior decoration, thus more colors are coming on the way.
- Headphone/headset, dual driving design, build-in headphone amp can be closed. RCA line out to fancy headphone amp can drive reference headphones as well.

Specification:
