Gustard U26Digital Interface USB I2S SPDIF 32bit 1536kHz DSD2048 Black
The Gustard U26 is a high-precision USB digital interface designed to deliver ultra-high-resolution audio quality to audiophiles and professionals. Developed in collaboration with Amanero Technologies, it transmits digital audio signals with exceptional accuracy and stability, minimizing jitter and electrical interference. With its isolated architecture, low-phase-noise OCXO clocks, and compatibility with PCM formats up to 32-bit 1536kHz and DSD2048, the U26 fits perfectly into high-end audio setups, whether for home or professional use.
Gustard U26: Cutting-edge technology for optimal audio quality
The Gustard U26 uses an ARM Cortex-M7 processor and a custom USB solution, the result of collaboration between Gustard and Amanero. This technology enables real-time management of very high-resolution audio streams, with reduced latency and increased stability.
Gustard U26: High-precision clock
The Gustard U26 is also equipped with an OCXO clock as its clock source, combined with K2 PLL technology, ensuring ultra-precise synchronization and significantly reduced jitter, which is essential for high-quality sound reproduction.
Gustard U26: Maximum compatibility
The U26's USB 2.0 interface provides Plug & Play compatibility with Mac, Windows, Linux, and mobile devices (OTG). For Windows users, a custom ASIO driver is available, allowing fine-tuning of latency and buffer settings, as well as phase and data alignment adjustments, for total optimization of the audio chain.
Gustard U26: Optimized insulation and power supply
The Gustard U26 features a fully isolated power supply architecture, with a toroidal transformer and independent linear regulators for the USB and digital circuits. This physical and electrical separation eliminates noise and interference, ensuring a pure and stable audio signal. The U26 also incorporates a 200Mbps USB isolation chip, which effectively blocks electrical noise from the computer or streamer, preserving the integrity of the audio signal.
Gustard U26: Comprehensive connectivity
The U26 offers a wide range of digital outputs: Coaxial (RCA and BNC), Optical, AES (XLR), and I2S via HDMI, providing maximum compatibility with most DACs and audio systems. This versatility makes it an ideal choice for users who want to easily integrate the interface into their existing audio system, whether domestic or professional.
