SOUND WARRIOR USB converter with clock input function Made in Japan High-performance D/A SWD-DA20-SD

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. [Enjoy high-resolution sound sources to the fullest] Compatible with linear PCM44.1k-384kHz/16-32bit, DSD2.8M-11.2MHz. The DAC is equipped with ESS Technology's high-performance audio DAC IC "ES9018K2M". Digital inputs include one each for USB, coaxial (COAXIAL), and optical (OPTICAL), allowing connection to PCs, CD transports, and various other digital devices. You can enjoy high-resolution sound sources and CDs in high quality. [Enjoy your favorite songs in various formats! ] This unit has a built-in SRC (sampling rate converter) that allows you to upsample the input sound source data with the touch of a button and enjoy the changes in the sound. You can also enjoy the changes in the sound by converting the PCM data input to this unit to DSD data, and converting DSD data to PCM data. You can select your preferred sampling rate and format for each song and enjoy creating your own sound. In addition, if you want to output the input data as it is, there is also a BYPASS mode that plays through without passing through SRC. [Preamp-like configuration] In addition to 3 digital inputs compatible with high resolution, there is also 1 analog input (RCA LR terminal), each of which can be switched using the selector switch on the front panel. It can be used as an audio component positioned like a preamplifier that can be installed on your desktop. Additionally, when connected to a power amplifier with a volume, the unit is equipped with a circuit that skips the volume. This is a special feature designed for ease of use, where you want to reduce as much as possible the circuits that lead to sound quality deterioration, such as volume. [Commitment to Headphone Amplifiers] As a headphone manufacturer, we do not allow compromise when it comes to headphone amplifiers. For the headphone amplifier of this unit, we selected a headphone amplifier IC that outputs as high quality as possible without altering the information contained in the sound source. [Invitation to synchronize with external clock] Not only can you easily enjoy high-quality sound by simply connecting this unit to a PC or CD transport, but you can also enjoy creating a higher-grade sound by adding other equipment. For example, by connecting an external clock to the clock generator "SWD-CL10" of this series and synchronizing operation with other digital devices, you can enjoy creating even higher-definition sounds. [Compatible with the new USB data transfer method "Bulk Pet"] Generally, USB Audio data is transferred using the "Isochronous" method. This method processes a large amount of data in a short period of time and transfers it intermittently, which places a high processing load on the CPU on the host side and the CPU on the device side. High processing load also affects sound quality. The "Bulk Pet" method makes it possible to average the amount of data to be processed by reducing the amount of data to be transferred as much as possible and making the data transfer continuous. This is an innovative transfer method that reduces fluctuations in the processing load on the host and device CPUs and improves sound quality. SWD-DA20-SD supports "Bulk Pet" by installing a driver compatible with "Bulk Pet" High-performance USB D/A converter with clock input function This unit is a [2022 model] headphone amplifier with a built-in USB DAC that maintains the functions of the SWD-DA20, which has been well-received as the core of the SW Desktop-Audio series, but has revised some of the parts and housing (case) used. It packs a variety of ways to enjoy audio into a compact size that can be placed on your desktop. Compatible with playback of most currently available high-resolution sound sources (linear PCM 44.1k to 384kHz/32bit, DSD 2.8M to 11.2MHz). We believe that the basic function of ``converting the input sound source data to analog and outputting it in the highest possible quality'' is the most important function for a D/A converter, and we developed it with great care. This unit is also equipped with functions that allow users to enjoy various changes in the sound themselves. For example, it has a built-in sampling rate converter (SRC) that upsamples the input sound source data, and also has the ability to convert PCM ⇔ DSD formats in real time. This allows you to enjoy your favorite songs at your favorite sampling rate and format. Furthermore, you can enjoy even higher quality sound creation by synchronizing operation with other digital devices (SWD-CT10, etc.) by connecting an external clock. It packs a variety of ways to enjoy audio into a compact size that can be placed on your desktop. [Product specifications] Power supply: DC12V (AC adapter) Body size: Approx.
