Updated on 2022-01-24
Changes and improvements about new firmware are as follows :
1.Added memory function for turning indicator light off; (You could switch indicator light option between Turn off(until device restart) and Turn off(always) via Android version FiiO Control APP. Turn off(until device restart):Turn off the indicator light for now and turn it on again after the device restarts; Turn off(always): Keep turning off the indicator light until the setting changes.)
2.Added dynamic power policy adjustment function; (With this enabled,the system will dynamically adjust the power policy according to the playback sampling rates,so when playing tracks with lower sampling rates, the power consumption and heat generation will be effectively reduced.
3.Added hardware mute switch function; (The device is embedded with a hardware mute switch, which can mute the impulsive sound that occurs when switching between tracks of different sampling rates. However, when the mute switch functions,it will also make a slight pop sound. You may choose to enable or disable it according to your preference.)
