JM21 FW1.0.6 firmware changes are as follows:

1. Added system PEQ (Parametric Equalizer) feature

2. Added ALL TO DSD feature

3. Added MQA decoding support

4. Added DoP support for USB DAC

5. Added iPhone decoding support in USB DAC mode

6. Added new WiFi sleep mode strategy to optimize standby power consumption

7. Fixed occasional automatic reboot issue when shutting down with OTG cable connected

8. Miscellaneous performance improvements and bug fixes

Notes:

1. Before connecting an iPhone for decoding, enable the “iOS Device Decoding” switch in the USB DAC settings.

2. The new version adds the “Keep WLAN connection during sleep” option on the WiFi list page. When disabled (default), WiFi will automatically turn off during system sleep and reconnect upon wakeup, significantly reducing power consumption. Enabling this option maintains a WiFi connection during sleep with moderately higher power usage.

1.新增系统PEQ功能

2.新增ALL TO DSD功能

3.新增MQA解码支持

4.新增USB DAC解码DOP支持

5.新增USB DAC模式支持iPhone解码

6.新增WiFi休眠关闭策略,优化待机耗电

7.修复连接OTG线关机机器几率性出现自动重启问题

8.其他性能优化及Bug修复

注1:连接iPhone解码前,需在USB DAC设置下开启“iOS设备解码”开关

注2:新版本在WiFi列表界面新增“在休眠状态下保持WLAN连接”选项。该选项在默认关闭状态时,WiFi在系统休眠时将会自动关闭,并在系统唤醒时自动打开回连,可有效降低系统休眠时的耗电;您也可以开启该选项,在休眠状态下保持WiFi连接,此时休眠休眠耗电较关闭状态下偏大一些
