●Product introduction
Le Bang Jasmine(Moli)The sound card product is a PCI interface sound card for high-quality music appreciation for music enthusiast users. This product uses VIA Envy24 series professional audio chip and XILINX general field programmable gate array(FPGA)The chip is used for interface control and data processing, combined with Ti''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s high-performance digital-to-analog conversion chip and high-performance operational amplifier, so that this product has high-quality sound fidelity and high-speed audio processing characteristics.
· practical functional interface
The Jasmine sound card has a high-quality RCA stereo line output and a 3.5mm stereo headphone output interface. The line and headphone output can be switched by the control panel, which is convenient for users to connect the speaker system and headphones at the same time.
The earphone output of the Jasmine sound card is driven by a special headphone amplifier circuit, which has strong driving ability and is suitable for connecting earphones or earplugs with medium and low impedance for personal music appreciation purposes.
The Jasmine sound card has a digital optical output interface that can output pure stereo PCM encoded signals and multi-channel Dolby Digital(AC-3), DTS digital signal, you can get a better music appreciation effect by connecting an external advanced audio decoder. You can also connect to an AV system with decoding function to experience the immersive surround sound effects of watching DVD blockbusters, and enjoy unprecedented cinematic effects. You can also connect MD devices for digital music transcription.
The 2Pin S/PDIF interface of the Jasmine sound card can be connected to a high-definition graphics card with S/PDIF input to achieve simultaneous HDMI high-definition output; the unique 10Pin digital expansion interface can be connected to the digital daughter card of Lezhibang(Optional), To achieve optical fiber and coaxial output function.
· high-quality audio characteristics
The Jasmine sound card supports up to 24Bit/192KHz format sound effect processing, and adopts a digital-to-analog conversion chip with a signal-to-noise ratio of up to 113dB and a dynamic range to provide high-fidelity sound quality analog output effects.
The precision linear voltage regulator circuit provides a stable and less disturbing power supply effect, so that the analog circuit can work in the best state.
Lezhibang''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s unique balanced analog filter amplifier circuit, matched with high-performance operational amplifiers and capacitors, provides the most musical sound effects.
XILINX FPGA chip cooperates with VIA Envy24 professional audio control chip, avoiding SRC process and system Mixer, ensuring the fidelity of audio playback to the greatest extent.
FPGA is also used to provide a precise clock, and build a huge asynchronous buffer to generate precise audio timing, so that the audio signal quality is only accurate before, and provides the smallest jitter output.
The precision S/PDIF transmitter integrated inside the FPGA outputs S/PDIF signals, which can complete popular digital signal output such as PCM, Dolby Digital, and DTS. Because this S/PDIF transmitter is driven by a precision clock, the output signal jitter is very low, which fully meets the accuracy required by the audio laboratory for test equipment.
Jasmine sound card also supports ASIO, providing ultra-low audio delay characteristics.
· flexible software support
By installing the unique driver developed by Lezhibang, it can provide perfect ASIO, WDM support and mainstream operating systems Windows XP, Windows VISTA, Windows7, etc.
You can also continue to optimize and update the driver program by Lezhibang in the later period, so that the Jasmine sound card can play a more excellent audio performance.
