Factory Pictures:
Company's own plant : 50,000 sqm; Employees : 930+; Monthly
production capacity : 100,000 m2 PCBA Applications High-Resolution Audio Playback and Streaming: The PCBA processes and decodes high-bitrate audio streams (up to
192kHz/24-bit) from classical music streaming services, ensuring
faithful reproduction of complex orchestral arrangements, subtle
dynamics, and wide soundstage essential for discerning listeners . Dedicated Classical Music Library Management: Enables users to organize, browse, and access extensive classical
music collections by composer, conductor, orchestra, or period,
with the PCBA managing metadata and large storage systems (SD cards
or networked drives) for seamless navigation . Multi-Room and Whole-Home Audio Distribution: Powers networked streaming endpoints that synchronize playback
across multiple rooms, allowing classical music to fill an entire
home with perfectly timed, phase-aligned audio for an immersive
listening experience. Critical Listening and Studio Monitoring: Serves as a reference-grade playback system for audio engineers,
producers, and musicians who require accurate, uncolored
reproduction of classical recordings for mixing, mastering, or
analytical listening sessions. Educational and Music Appreciation Tool: Provides music students and educators with a platform to study
orchestral works, analyze performances, and access accompanying
program notes or visualizations synchronized with the audio stream
. Integration with Legacy Hi-Fi Systems: Functions as a modern streaming bridge for traditional stereo
systems, allowing high-end amplifiers and speakers to receive
streaming content via digital-to-analog conversion that meets the
standards of classical audiophiles . Concert Hall and Performance Venue Applications: Deployed in public spaces, lobbies, or pre-concert areas to
provide curated classical music programming with consistent,
high-quality output that sets an appropriate atmosphere.
PCBA Features High-Performance Digital-to-Analog Converter (DAC) and Analog
Output Stage: The PCBA integrates a premium DAC chip (such as Cirrus Logic
CS4398) capable of sampling rates up to 192kHz, paired with
precision analog output circuitry that delivers pristine,
low-distortion audio signals to amplifiers or headphones . Network Streaming and Connectivity Processor: Features a dedicated network processor or Wi-Fi/Bluetooth module
for reliable, buffer-free streaming from services like Tidal,
Qobuz, or local network servers, with support for lossless and
high-resolution audio formats . Digital Audio Receiver and Clock Management: Incorporates a precision digital audio receiver chip (e.g.,
CS8416) with low-jitter clock recovery and phase-locked loop (PLL)
circuitry to maintain perfect timing synchronization, critical for
preserving the spatial cues and temporal accuracy in classical
recordings . Multiple Digital and Analog Input Options: Includes a comprehensive input matrix with optical (TOSLINK),
coaxial S/PDIF, USB audio, and analog line inputs, allowing the
streaming hardware to serve as a central hub for all audio sources
in a classical music system . Headphone Amplifier with High Current Drive: Features a dedicated, high-fidelity headphone amplifier stage
capable of driving demanding high-impedance headphones favored by
classical listeners, with sufficient headroom for orchestral
crescendos without distortion . User Interface and Display Controller: Integrates drivers for high-resolution LCD or OLED displays that
can show album artwork, detailed track information (composer,
movement, opus number), and playback status, often with tactile
controls for intuitive navigation . Advanced Power Management and Low-Noise Regulation: Employs a sophisticated power supply design with separate analog
and digital regulation, using RF chokes and extensive filtering to
isolate sensitive audio circuits from power supply noise, ensuring
the quiet background essential for classical music's dynamic range.
