Standard firmware APP_V0.8.9 (data: 20231224) Download link 【The QA662 is this firmware by default】
Standard firmware APP_V0.8.10(data:20240610)Download link 【Users with high audio quality requirements are advised not to use this version】
1. Fixed the BUG where screen brightness adjustments could not be saved.
2. Added a scrolling display feature for long file names under the folder/song list for pure playback.
Clark's assessment of the sound quality of this firmware: Compared to firmware V0.8.9, due to the addition of some code, this version has undergone dozens of modifications to the sound, yet it still does not match the original. Specifically, the mid and low frequencies are not as solid as before, and the sound imaging appears slightly scattered and floaty. Of course, with different systems, the situation may vary; the actual sound you hear should be taken as the standard.
Pure WAV version firmware WAV_V1.1 (data:20240814)Download link 【With this firmware, Pure playback supports only the WAV format.】
1. Fixed the BUG where screen brightness adjustments could not be saved.
2. Added a scrolling display feature for long file names under the folder/song list for pure playback.
3. Removed the code for all audio formats except WAV from the QA662's pure playback.
4. The MCU's clock frequency has been reduced from 290 MHz to 180 MHz, further reducing electromagnetic interference on the QA662 circuit board.
5. The buffer for linearly reading SD card data during pure audio playback has been increased to twice its original size (because only one format, WAV, is supported now, the MCU has more free time to read the card).
Clark's assessment of the sound quality of this firmware: Compared to the default APP_V0.8.9 version, thanks to the reduced MCU frequency and the increased buffer for linearly reading SD card data, the sound of this firmware is closer to a HI-END CD turntable. The overall sound background is cleaner, the separation between notes is better, and the depth of the sound is improved. However, it may not be suitable for all users. On one hand, it only supports one audio format, WAV, and on the other hand, its sound style is somewhat different from the default firmware. The sound is more vivid, with more detail in the high-frequency range.
QA662 Firmware Upgrade Method:
1. Download the firmware, decompress it, and extract the *.qls file below.
2. Copy the *.qls firmware file to the root directory of a TF or SD card using a card reader. (The sd/tf card can contain multiple versions of the firmware, and any existing music files on the sd/tf card will not be affected.)
3. If the firmware file cannot be found during the upgrade, you can also move the firmware file to any music folder that the QA662 can access.
4. Insert the TF/SD card with the copied firmware into the right side of the QA662 device.
5. Press and hold the play button on the QA662 device's panel, do not release it, then turn on the power switch to power on. The QA662 will prompt that it has entered upgrade mode and allow you to select the upgrade file.
6. Select the firmware you wish to upgrade and press the play button to confirm.
7. The upgrade will then proceed. After a few seconds, once the upgrade is complete, you will be prompted to restart the device.
8. Turn off the device and restart it to use it normally.
9. Do not disconnect the power during the upgrade process. If the upgrade fails, simply repeat the upgrade procedure.
10. Firmware versions do not have a sequence; you can flash any version of the firmware at any time.

MUB1的整体声音走向与QA361、QA390LE算是一脉相承的。但因为MUB1这类机器大家连续听的时间通常会较长,因此耐听、好听又相对会放到更重要的位置。整体声音温润、细腻、安定、耐听,有着不错的声音密度与结像实体感,纵向空间感与层次细节都非常的优秀
