  TONE 1 Professional Hi-Fi DAC for Audiophiles   XMOS XU208-128-QF48 8 cores up to 500MIPS, compatible with USB 2.0.   Ultra-Quiet Power Ultra-low noise, high PSRR LDO designed to power Hi-Fi applications.   RCA Connector High-quality RCA, let you enjoy audio with delicate, clear, powerful and rich sound details.   ESS ES9038Q2M DAC The industry's highest performance 32-bit mobile DAC with unprecedented dynamic range and ultra-low distortion.   Accurate Low-Noise Clock Ultra-low phase noise crystal oscillator with excellent phase noise characteristics.   Compatible Audio File Formats APE, FLAC, OGG, WAV, ACC, ALAC, MP3, WMA, DSD, and more!     DESCRIPTION       Tone Board is a USB external HiFi sound card specially developed for Khadas VIMs by Khadas brand series products. Its superior performance and compatibility take the audiovisual experience to a whole new level. We integrated the advanced XMOS multi-core RISC microcontroller and ESS flagship 32-bit stereo mobile audio DAC ES9038Q2M into a small PCB. At the same time, we selected three independent high-performance OPAs and four ultra-low phase jitter oscillators for the audio system. As you can imagine, each power path is controlled by a separate ultra-low noise CMOS linear regulator with an OPA of ± 5.5V. In addition to the powerful hardware configuration, we also maximize the performance through excellent design.       PERFORMANCE DATA FROM ESS PROFESSIONAL LABS                                                                                     Total Harmonic Distortion + Noise ≤ 0.000337%                                                                                                      Signal / Noise Ratio ≥ 120dB                                                                                                   Dynamic Noise Reduction ≥ 120dB                                                                                             Crosstalk (Channel Separation) ≥ 127dB                                                                                                    Frequency Response ± 0.08dB                                                                                                     Sampling Rate and Compatibility                                                                                                        Ultra-Low Phase Noise Clock Jitter                                                                                            Supports Multiple Lossless Audio Formats   TWO VERSIONS GENERIC AND VIM EDITIONS            Generic Edition                                                   VIM Edition The universal version is designed to work with a                                            The VIM version is designed to "docking" with Khadas standalone Mac, PC or SBC via the built-in USB-C data                                Edge V, VIM3L, VIM3, VIM2 and VIM1 SBC to form a and power port.

You can also  headers on the board.                                                                                     use radiators and fans with the Tone Board.   INTERFACES FLEXIBLE I/O SUPPORTS DEVELOPMENT Khadas aims to gradually realize the ideas and dreams of developers to help makers grow. The two versions of the Tone Board's RCA output interface are the same, both have 2 RCA for analog output @ 2.0Vrms, and 1 RCA for S / PDIF input or output.   Expansion: 1 30-pin FPC connector for 8-channel analog output expansion Two 10-pin FPC connectors for OLED display and I2S expansio Other: One 40-pin female connector for VIM A 20-pin SMT header for debugging XMOS and VIM Users can directly connect their Tone Board to the PC via the USB-C interface, and the Tone Board is the ideal choice for audio developers. Khadas' New VIM Heatsink can also be used with VIM and Tone Board. COMPATIBILITY TONE BOARD SUPPORTS MULTIPLE OSES   SPECIFICATIONS
