Hardware:
• USB 2.0 High-Speed (480MHz) Audio / MIDI system
• Leading edge performance technology based on an affordable, low current chipset
• 32-bit audio processing with 10 input and 10 output channels at 192kHz
• Optionally up to 19 input and 19 output channels at max. 96kHz
• Optionally up to 36 input and 36 output channels at max. 48kHz
• Samplerates: 44.1kHz to 384kHz, optional DSD support
• USB2.0 bus- or self-powered power supply mode
• Sensationally low jitter using an on-chip audio PLL
• No samplerate conversion or clock recovery for true 1:1 audio
• Assignable stereo (1/4” TRS) line input and headphone output on the eval board
• Assignable Digital Interface (coax) for S/PDIF or AC3/DTS on the eval board
• Up to five MIDI input and output ports (fast USB2.0 I/O bulk transfer)
• Can be slaved to any I2S digital audio interface (CODEC or DIR/DIT as master)
• Based on the low cost (<EUR 4.00) 32-bit high performance Microchip® ATSAMA5D21 microprocessor
Software:
• For Windows (10 and 11, 32-bit and 64-bit), Mac OS, iOS and Linux systems
• Multi-application mode - simultaneous ASIO and/or WDM playback
• Extremely low latency Windows ASIO driver (adjustable in multiple parameters)
• USB interrupt mode transactions on Windows for better performance
• Fully USB Audio Class 2.0 compliant (isoc asynchronous mode)
• Software installer and advanced ASIO control panel for Windows
ASIO is a trademark and software of Steinberg Media Technologies GmbH. 
Firmware:
• Firmware updating while audio active via USB for programming future updates
• Audiomixer in firmware (low latency monitoring)
• USB tripple buffer capture and playback for lowest technically achievable latency
• Long term design experience with millions of USB Audio units licensed worldwide
