Product Features
Enjoy High-Resolution Sound Source
This device supports linear PCM 44.1k - 384kHz / 16 - 32 bit / DSD2.8 - 11.2 MHz playback. The DAC is equipped with the ES9018K2M high-performance audio DAC IC made by ESS Technology, which is known for sound quality. You can enjoy high-resolution sound sources and CDs in high quality
Upsampling / Format Conversion Function (SRC)
The built-in SRC (sampling rate converter) allows you to upsample the input audio source data with a single button and enjoy the sound change. You can also convert the PCM data input into the unit to DSD data and DSD data into PCM data respectively, so you can enjoy changing sound. (*There are some restrictions in the selectable sampling rate and format. Please refer to the "SRC Mode Compatibility Chart" for more information. If you want to output the data as it is, it also has a BYPASS mode that plays through without SRC. Choose your preferred sampling rate and format for each song, and enjoy the sound you want
Preamplifier-like configuration
The digital inputs are USB, coaxial, and optical, allowing connection to a variety of digital devices such as PCs, CD transports, and network audio servers. Each input can be easily switched using the selector switch on the front panel. This unit can be used as an audio component with a preamplifier-like function.
Attention to Headphone Amplifier
We are also headphone manufacturers, so we don't accept any compromises for headphone amplifiers. In this headphone amplifier, the headphone amplifier IC has been selected according to the development guidelines of this device's "output as high quality as possible without needing to modify the information held by the sound source. Enjoy the sound source appeal straight and high definition headphones
Supports the new USB data transfer method "Bulk Pet"
In general, USB Audio data transfer is transmitted using "Isochronous" method. This method handles large amounts of data in a short period of time and intermittently transfers the Host side CPU and Device-side CPUs. The sound quality will also be affected by high processing loads. The "Bulk Pet" method allows for an average amount of data to be processed by using as much as possible and continuous data transfer. This is a revolutionary transfer method that allows for less handling load fluctuations on Host/Device-side CPUs and improved sound quality. The SWD-DA15 supports "Bulk Pet" by installing the driver on your PC. Bulk Pet is a registered trademark of Interface Co., Ltd
