6. Darwin

1. What is Darwin? Darwin architecture is a new high-definition audio processing architecture independently developed by HiBy. It is derived from traditional R2R technology and integrates R2R resistor network linear technology. It pioneered the application of adjustable pure FIR filters, harmonic controllers, NOS/OS switching, DSD pass-through and other functions on portable playback devices. At the same time, its flexible architecture design is independent and controllable throughout the entire process, which also creates infinite possibilities for later upgrades and iterations, allowing the equipment using it to have the imagination space for continuous evolution.

2. Digital filter mode Used to select different digital filters to provide different listening experiences.

3. US

   • Non OverSampling is a method for digital-to-analog conversion in which an audio signal is converted directly from its digital form to an analog signal without going through an oversampling process. To fully understand NOS, you must first master the basic concepts of digital-to-analog conversion and oversampling.
   • In digital-to-analog conversion (DAC), a digital audio signal composed of discrete samples is converted into a continuous analog signal that can be amplified and played through a speaker or headphone. This process is essential for converting digital audio data into sounds that can be heard and appreciated.
   • On the other hand, oversampling involves increasing the sampling rate of the audio signal beyond the original sampling rate. The technique is designed to reduce distortion and noise by averaging multiple samples, which theoretically improves the quality of the conversion. Oversampling is often used in modern DACs for improved performance and accuracy.
   • NOS DAC skipped this extra step. These DACs do not perform oversampling, but convert at the original sample rate of the audio signal. This approach can lead to different audio experiences, often characterized by its unique sound quality.

4. Harmonic controller

   • The main adjustment of the harmonic controller is the second harmonic, because generally speaking, the human ear prefers even harmonics because compared with even harmonics, odd harmonics are more harsh and discordant in the hearing.

7. MSEB

The top areas are reset MSEB, MSEB setting entry, and MSEB switch respectively

• Swipe up and down to show more adjustments
• Slide left and right to adjust the settings of corresponding items
• MSEB is only valid for songs not higher than 96kHz
• Invalid for DSD and MQA songs

8. Playback settings

Play Settings

1. EQ (EQ) The top areas are reset equalizers, select the preset equalizer menu entry, and equalizer switch

   • By sliding left and right, different equalizer bands are displayed
   • Slide up and down the slider of different frequency bands to adjust the gain/attenuation dB value of the corresponding frequency bands
   • Draw the corresponding curve according to the position adjusted by different frequency bands
   • Equalizer is only valid for songs not higher than 48kHz
   • Invalid for DSD and MQA songs

2. Update database Start scanning songs manually

3. Music update mode

   • Manually, the user needs to manually update the song library
   • Automatically, if the MicroSD(TF) card is detected or the USB is plugged in, the system will automatically rescan the song library.

4. Playback mode

   • List playback: Starts from the selected track until the current list playback is completed and plays stop.
   • Single loop: The same song is repeated until it is manually cut or shut down and the playback stops.
   • Shuffle: Randomly select the next song in the current list to start playing until it stops manually or shuts down, and stops playback.
   • List loop: Starting from the selected track, continuously looping the songs in the current list until they are manually stopped or shut down, and the playback is stopped.

5. Output selection

   • Since PO/LO multiplexes the same output port, this option is used to switch PO/LO outputs

   • When the audio output is Bluetooth, DSD output mode cannot be selected. This function is invalid and is converted to PCM output;
   • When the audio output is SPDIF, DSD output mode selection can be performed Select PCM and output according to the sampling rate 88.2kHz Select DoP or Native. When playing DSD64, it will be output in DoP mode, and the output sampling rate is 2.8 MHz; Select DoP or Native. When playing DSD128 and DSD256, they are converted to PCM output, with an output sampling rate of 88.2 kHz.
   • When the audio output is USB Audio Out, DSD output mode selection can be performed Select PCM, press PCM to output, the maximum support sampling rate is 384kHz Select DoP, press DoP to output, and support DSD256 (11.2MHz) at most (condition: The decoding device that needs to be accessed supports DSD decoding. If the device does not support it, the playback fails) Select Native, press Native to output, and support DSD256 (11.2MHz) at most (condition: The decoding and decoding device that needs to be accessed supports DSD decoding. If the device does not support it, the playback fails)

7. DSD Gain Compensation Since DSD audio is lower than PCM, you can adjust certain compensations yourself as needed to keep DSD and PCM at the same output level.

USB Audio Guide

USB audio description

When the player works on USB audio, you can think of the player as a USB HD decoding receiver or as a USB sound card. The player works on USB audio supports the USB Audio Class 2.0 (UAC2) protocol, but does not support USB Audio Class 1.0 (UAC1), so the host side also needs to support USB Audio Class 2.0 (UAC2).

Different host systems will have different power supply, so USB DACs offer two working modes:

USB DAC working mode

1. USB charging (the lever toggle remains in the middle) After selecting this mode, the current provided by the host is not only used to work and use the player, but also to charge the player. Therefore, it is recommended to choose this mode in scenarios where the host power supply current is large, such as when the host is a computer.

2. USB does not charge (the lever is to be locked to charge state) After selecting this mode, the current provided by the host is only used to work for the player. Therefore, it is recommended to select this mode in scenarios where the host power supply current is small. For example, when the host is a mobile phone, select this mode.

There are certain differences in the support of USB Audio Class 2.0 (UAC2) for different host systems. Please confirm the support according to the corresponding system. Please jump to the details.Here, the following provides a brief reference:

Support situation of different hosts

1. Windows Windows (Win7/Win8/Win10 1703 previous version) does not support the USB Audio Class 2.0 (UAC2) protocol, so drivers are required to be installed to use. Please refer to the driver installation.Here。
   Windows (Win10 1703 later) begins to support USB Audio Class 2.0 (UAC2) protocol, plug and play. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

2. MacOS MacOS itself already comes with a driver, and you can connect the player to the MacOS computer via a USB cable. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

3. Linux distribution Linux's USB DAC support is determined by the kernel. Whether the kernel of different distributions is turned on USB sound card functions is uncertain. For Linux distributions of unsupported USB DACs, you can compile the kernel to implement USB sound card functions by yourself. Or find a third-party app to support USB DAC functionality. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

4. Android The Android side distinguishes between exclusive and non-exclusive methods.

Android non-exclusive Just plug the USB decoder (such as HiBy FC4/HiBy FC6) into the USB port of your phone and use it. If you insert it, you can download HiBy Music and try the exclusive mode of HiBy Music. Otherwise, the phone will not support it. Please contact the mobile phone manufacturer to confirm.

Exclusive Android use Download, install HiByMusic. Enter HiByMusic. Swipe right to open the settings options -> Settings -> Click HiByMusic exclusive USB output, open the exclusive output. Insert the USB decoder (such as HiBy FC4/HiBy FC6) directly into the phone. The phone will pop up "Allow SeaByMusic to access HiBy FC4" and click Allow.

It is recommended to use USB without charging, saving battery power of your phone or tablet.

5. iOS iOS itself already comes with a driver, and you can connect the player to iPhone/iPad via a USB cable. It is recommended to use USB without charging, saving battery power of your phone or tablet.

6. Game console So far, XBOX/PS/Switch and other game consoles only support USB Audio Class 1.0 (UAC1), so the player's USB audio function cannot be used through the game console.
